1. Unfolding the effects of final-state interactions and quantum statistics in two-particle angular correlations

Abstract: Angular correlations of identified particles measured in ultrarelativistic proton-proton (pp) and heavy-ion collisions exhibit a number of features which depend on the collision system and particle type under consideration. Those features are produced by mechanisms, such as (mini)jets, elliptic flow, resonance decays, and conservation laws. In addition, of particular importance are those related to the quantum statistics (QS) and final-state interactions (FSIs). In this paper we show how to unfold the QS and FSI contributions in angular correlation functions by employing a Monte Carlo approach and using momentum correlations (femtoscopy), focusing on pp reactions. We validate the proposed method with PYTHIA 8 Monte Carlo simulations of pp collisions at $\sqrt{s}=13$ TeV coupled to calculations of QS and FSI effects with the Lednick\'y and Lyuboshitz formalism and provide predictions for the unfolded effects. In particular, we show how those effects modify the shape of the angular correlation function with emphasis on pions and protons. Most importantly, specific structures observed in the near-side region for both baryon-baryon and baryon-antibaryon pairs, originating from the strong interaction, are unveiled with the proposed method., Comment: 8 pages, 7 figures

2. Calculation of an Enhanced A1g Symmetry Mode Induced by Higgs Oscillations in the Raman Spectrum of High-Temperature Cuprate Superconductors

Abstract: In superconductors the Anderson-Higgs mechanism allows for the existence of a collective amplitude (Higgs) mode which can couple to eV light mainly in a nonlinear Raman-like process. The experimental nonequilibrium results on isotropic superconductors have been explained going beyond the BCS theory including the Higgs mode. Furthermore, in anisotropic $d$-wave superconductors strong interaction effects with other modes are expected. Here we calculate the Raman contribution of the Higgs mode from a new perspective, including many-body Higgs oscillations effects and their consequences in conventional, spontaneous Raman spectroscopy. Our results suggest a significant contribution to the intensity of the ${A}_{1g}$ symmetry Raman spectrum in $d$-wave superconductors. In order to test our theory, we predict the presence of measurable characteristic oscillations in THz quench-optical probe time-dependent reflectivity experiments.

Abstract: Studying spin-momentum correlations in hadronic collisions offers a glimpse into a three-dimensional picture of proton structure. The transverse single-spin asymmetry for midrapidity isolated direct photons in p ↑ + p collisions at s = 200 GeV is measured with the PHENIX detector at the Relativistic Heavy Ion Collider (RHIC). Because direct photons in particular are produced from the hard scattering and do not interact via the strong force, this measurement is a clean probe of initial-state spin-momentum correlations inside the proton and is in particular sensitive to gluon interference effects within the proton. This is the first time direct photons have been used as a probe of spin-momentum correlations at RHIC. The uncertainties on the results are a 50-fold improvement with respect to those of the one prior measurement for the same observable, from the Fermilab E704 experiment. These results constrain gluon spin-momentum correlations in transversely polarized protons.

4. S -wave contributions to the B(s)→χc1(ππ,Kπ,KK) decays

Author: Zhou Rui, Jia-Ming Li, Meng-Kun Jia, and Chao-Qi Zhang
Subjects: Physics, Particle physics, Pion, Meson, Branching fraction, Strong interaction, Order (ring theory), Perturbative QCD, Production (computer science), Invariant mass
Abstract: We make a detailed study of the three-body decays ${B}_{(s)}\ensuremath{\rightarrow}{\ensuremath{\chi}}_{c1}h{h}^{\ensuremath{'}}$, where ${h}^{{(}^{\ensuremath{'}})}$ is either a pion or kaon, by taking into account the $S$-wave states in the $h{h}^{\ensuremath{'}}$ invariant mass distribution within the perturbative QCD approach. The two meson distribution amplitudes are introduced to capture the strong interaction related to the production of the $h{h}^{\ensuremath{'}}$ system. We calculate the branching ratios for the $S$-wave components and observe large values of order ${10}^{\ensuremath{-}4}$ for some Cabibbo-favored decays, which are accessible to the LHCb and Belle II experiments. The obtained branching ratio $\mathcal{B}(B\ensuremath{\rightarrow}{\ensuremath{\chi}}_{c1}{K}_{0}^{*}(1430)(\ensuremath{\rightarrow}{K}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}))=({5.1}_{\ensuremath{-}0.8}^{+0.6})\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}5}$ consistent with the data from Belle within errors. Moreover, we also predict the differential distributions in the $h{h}^{\ensuremath{'}}$ invariant mass for the decays under consideration, which await the future experimental test. In addition, the corresponding ${\ensuremath{\chi}}_{c1}(2P)$ channels are also investigated, which are helpful to clarify the nature of the $X(3872)$ state.

5. Experimental Observations of Laser-Driven Tin Ejecta Microjet Interactions

Abstract: The study of high-velocity particle-laden flow interactions is of importance for the understanding of a wide range of natural phenomena, ranging from planetary formation to cloud interactions. Experimental observations of particle dynamics are sparse given the difficulty of generating high-velocity flows of many particles. Ejecta microjets are micron-scale jets formed by strong shocks interacting with imprinted surfaces to generate particle plumes traveling at several kilometers per second. As such, the interaction of two ejecta microjets provides a novel experimental methodology to study interacting particle streams. In this Letter, we report the first time sequences of x-ray radiography images of two interacting tin ejecta microjets taken on a platform designed for the OMEGA Extended Performance (OMEGA EP) laser. We observe that the microjets pass through each other unattenuated for the case of 11.7±3.2 GPa shock pressures and jet velocities of 2.2±0.5 km/s but show strong interaction dynamics for 116.0±6.1 GPa shock pressures and jet velocities of 6.5±0.5 km/s. We find that radiation-hydrodynamic simulations of the experiments are able to capture many aspects of the collisional behavior, such as the attenuation of jet velocity in the direction of propagation, but are unable to match the full spread of the strongly interacting cloud.

6. Is the Standard Model in the Swampland? Consistency Requirements from Gravitational Scattering

Author: 80822288, Aoki, Katsuki, Tran Quang Loc, Noumi, Toshifumi, Tokuda, Junsei, 80822288, Aoki, Katsuki, Tran Quang Loc, Noumi, Toshifumi, and Tokuda, Junsei
Abstract: We study compatibility of the standard model of particle physics and general relativity by means of gravitational positivity bounds, which provide a necessary condition for a low-energy gravitational theory to be UV completable within the weakly coupled regime of gravity. In particular, we identify the cutoff scale of the standard model coupled to gravity by studying consistency of light-by-light scattering. While the precise value depends on details of the Pomeron effects in QCD, the cutoff scale reads 10¹⁶ GeV if the single-Pomeron exchange picture works well up to this scale. We also demonstrate that the cutoff scale is lowered to 10¹³ GeV if we consider the electroweak theory without the QCD sector.

7. Direct and ultrafast probing of quantum many-body interactions through coherent two-dimensional spectroscopy: From weak- to strong-interaction regimes

Abstract: Interactions between particles in quantum many-body systems play a crucial role in determining the electric, magnetic, optical, and thermal properties of the system. The recent progress in the laser-pulse technique has enabled the manipulations and measurements of physical properties on ultrafast timescales. Here we propose a method for the direct and ultrafast probing of quantum many-body interaction through coherent two-dimensional (2D) spectroscopy. Using a two-band fermionic Hubbard model for the minimum two-site lattice system, we find that the 2D spectrum of a noninteracting system contains only diagonal peaks; the interparticle interaction manifests itself in the emergence of off-diagonal peaks in the 2D spectrum before all the peaks coalesce into a single diagonal peak as the system approaches the strongly interacting limit. The evolution of the 2D spectrum as a function of the time delay between the second and third laser pulses can provide important information on the ultrafast time variation of the interaction.

8. Deuteron-deuteron correlation function in nucleus-nucleus collisions

Abstract: A formula of the $D$-$D$ correlation function is derived. The deuterons are treated either as elementary particles or as neutron-proton bound states. In the first case the deuterons are directly emitted from a source and in the second one the deuteron formation is a final-state process simultaneous with a generation of $D$-$D$ correlation. The source radius of deuterons formed due to final-state interactions is bigger by the factor of $\sqrt{2}$ than that of directly emitted deuterons. To check how sizable is the effect we compute the $D$-$D$ correlation function taking into the Bose-Einstein statistics of deuterons, the $s$-wave scattering due to strong interaction and the Coulomb repulsion. The correlation function is shown to be sensitive to the source radius for sources which are sufficiently small with RMS radii smaller than 3.5 fm. Otherwise the correlation function is dominated by the Coulomb repulsion and weakly depends on the source radius. Measurements which can make use of our finding are discussed., 9 pages, 4 figures, published version

9. Computational approach to (ZnS)i nanoclusters in ionic liquids

Abstract: Unique and attractive properties have been predicted for II-VI-type semiconductor nanoclusters within the field of nanotechnology. However, the low reaction kinetics within the usual solvents gives only thermodynamic control during their production process, making the obtention of different metastable polymorphs extremely difficult. The use of ionic liquids as solvents has been proposed to overcome this problem. Identifying how these nanoclusters are solvated within ionic liquids is fundamental if this strategy is to be pursued. While computational chemistry tools are best suited for this task, the complexity and size of the system requires a careful design of the simulation protocol, which is put forward in this work. Taking as reference the ${(\mathrm{ZnS})}_{12}$ nanocluster and the [EMIM][${\mathrm{EtSO}}_{4}$] ionic liquid, we characterize the interactions between the nanoparticle and first solvation shell by density functional theory calculations, considering most of the solvent implicitly. The DFT results are consistent through different theory levels showing a strong interaction between the Zn atoms of the nanocluster and the [${\mathrm{EtSO}}_{4}^{\ensuremath{-}}$] anion of the ionic liquid. A more realistic representation of the system is obtained by classical MD calculations, for which various classical force fields were considered and several atomic interactions parameterized. This new set of parameters correctly describes the interaction of different (ZnS) nanoclusters, supporting its transferability. The resulting MD simulation shows the formation of a structured ionic liquid solvation shell around the nanocluster with no exchange of ions for at least 5 ns, in agreement with the strong interactions observed in the density functional theory calculations.

Abstract: Using infrared spectroscopy, the authors study here how the low-energy charge carrier dynamics and band structure of the candidate axion topological insulator EuIn${}_{2}$As${}_{2}$ are affected by its antiferromagnetic transition at ${T}_{\text{N}}$ =18 K. The free carriers are shown to have a plasma frequency of about 2000 cm${}^{\ensuremath{-}1}$, and a scattering rate with a cusplike maximum at ${T}_{\text{N}}$ that signifies their strong interaction with the fluctuating Eu spins. The authors also observe large band splittings and a phonon anomaly below ${T}_{\text{N}}$, which indicate that the charge, spin, and lattice excitations are strongly coupled.

The results are achieved through a femtoscopic analysis of ΛK correlations in Pb-Pb collisions at sNN=2.76 TeV recorded by ALICE at the Large Hadron Collider. The femtoscopic correlations result from strong final-state interactions and are fit with a parametrization allowing for both the characterization of the pair emission source and the measurement of the scattering parameters for the particle pairs. Extensive studies with the THERMINATOR 2 event generator provide a good description of the nonfemtoscopic background, which results mainly from collective effects, with unprecedented precision. Furthermore, together with HIJING simulations, this model is used to account for contributions from residual correlations induced by feed-down from particle decays. The extracted scattering parameters indicate that the strong force is repulsive in the ΛK+ interaction and attractive in the ΛK- interaction. The data hint that the ΛKS0 interaction is attractive; however, the uncertainty of the result does not permit such a decisive conclusion. The results suggest an effect arising either from different quark-antiquark interactions between the pairs (ss¯ in ΛK+ and uū in ΛK-) or from different net strangeness for each system (S=0 for ΛK+, and S=-2 for ΛK-). Finally, the ΛK systems exhibit source radii larger than expected from extrapolation from identical particle femtoscopic studies. This effect is interpreted as resulting from the separation in space-time of the single-particle Λ and K source distributions.

12. Thermodynamically Induced Transport Anomaly in Dilute Metals ZrTe5 and HfTe5

Abstract: A 40-year-old puzzle in transition metal pentatellurides ${\mathrm{ZrTe}}_{5}$ and ${\mathrm{HfTe}}_{5}$ is the anomalous peak in the temperature dependence of the longitudinal resistivity, which is accompanied by sign reverses of the Hall and Seebeck coefficients. We give a plausible explanation for these phenomena without assuming any phase transition or strong interaction effect. We show that, due to intrinsic thermodynamics and diluteness of the conducting electrons in these materials, the chemical potential displays a strong dependence on the temperature and magnetic field. With that, we compute resistivity, Hall and Seebeck coefficients in zero field, and magnetoresistivity and Hall resistivity in finite magnetic fields, in all of which we reproduce the main features that are observed in experiments.

13. Coulomb and strong interactions in the final state of Hanbury-Brown–Twiss correlations for Lévy-type source functions

Abstract: We present detailed calculations about the expected shape of two-pion Bose-Einstein [or Hanbury-Brown–Twiss (HBT)] correlations in high energy heavy ion collisions that include a realistic treatment of final state Coulomb interaction as well as strong interactions (dominated by s-wave scattering). We assume Lévy type source functions, a generalization that goes beyond the Gaussian approximation. Various recent experimental results found the use of such source types necessary to properly describe the shape of the measured correlation functions. We find that strong interaction effects for like-sign pions are small, but their consideration may become important in future precision measurements, especially if one considers source parameters beyond the Gaussian HBT radii. Precise experimental determination of these source parameters (such as Lévy stability exponent, correlation strength, etc.) may then benefit from the inclusion of the treatment of strong interaction not just for heavier particles (e.g., protons, Λs) but also in case of two-pion measurements.

Abstract: After more than 80 years from the seminal work of Weizs\"acker and the liquid drop model of the atomic nucleus, deviations from experiments of mass models ($\sim$ MeV) are orders of magnitude larger than experimental errors ($\lesssim$ keV). Predicting the mass of atomic nuclei with precision is extremely challenging. This is due to the non--trivial many--body interplay of protons and neutrons in nuclei, and the complex nature of the nuclear strong force. Statistical theory of learning will be used to provide bounds to the prediction errors of model trained with a finite data set. These bounds are validated with neural network calculations, and compared with state of the art mass models. Therefore, it will be argued that the nuclear structure models investigating ground state properties explore a system on the limit of the knowledgeable, as defined by the statistical theory of learning.

Abstract: Monolayer semiconductors have the potential to transform the industry, but their intrinsic properties are difficult to characterize due to strong interaction with the environment. This study uses multidimensional coherent spectroscopy to measure the intrinsic homogeneous linewidth of a monolayer transition-metal dichalcogenide that has been isolated from its environment through encapsulation. The measurements reveal that the linewidths become substantially narrower after encapsulation, indicating reduced sample degradation. These findings have the potential to impact the materials and process-control methods used in the semiconductor industry.

Abstract: In most experiments with atoms trapped in optical lattices, the transverse size of the optical lattice beams is of the order of tens of micrometers, and loading many atoms into smaller optical lattices has not been carefully investigated. We report trapping 1500 $^{171}\mathrm{Yb}$ atoms in a one-dimensional optical lattice generated by a narrow cavity mode at a distance of 0.14 mm from a mirror surface. The simplest approach of loading atoms from a mirror magneto-optical trap overlapped with the cavity mode allows the adjustment of the loading position by tuning a uniform bias magnetic field. The number of atoms trapped in the optical lattice exhibits two local maxima for different lattice depths, with a global maximum in the deeper lattice. These results open a way to quantum mechanical manipulation of atoms based on strong interaction with a tightly focused light field.

17. From triply charmed dibaryons to pentaquark states: A model-independent way to determine the spins of the Pc(4440) and Pc(4457)

Abstract: The LHCb Collaboration has recently observed three narrow pentaquark states---the ${P}_{c}(4312)$, ${P}_{c}(4440)$, and ${P}_{c}(4457)$---that are located close to the $\overline{D}{\mathrm{\ensuremath{\Sigma}}}_{c}$ and ${\overline{D}}^{*}{\mathrm{\ensuremath{\Sigma}}}_{c}$ thresholds. Among the so-far proposed theoretical interpretations for these pentaquarks, the molecular hypothesis seems to be the preferred one. Nevertheless, in the molecular picture, the spins of the ${P}_{c}(4440)$ and ${P}_{c}(4457)$ have not been unambiguously determined yet. In this paper, we point out that heavy-antiquark-diquark symmetry induces a model-independent relation between the spin splitting in the masses of the ${P}_{c}(4440)$ and ${P}_{c}(4457){\overline{D}}^{*}{\mathrm{\ensuremath{\Sigma}}}_{c}$ pentaquarks and the corresponding splitting for the ${0}^{+}$ and ${1}^{+}$ ${\mathrm{\ensuremath{\Xi}}}_{cc}{\mathrm{\ensuremath{\Sigma}}}_{c}$ triply charmed dibaryons. This is particularly relevant owing to a recent lattice-QCD prediction of the ${1}^{+}$ triply charmed dibaryon, which suggests that a calculation of the mass of its ${0}^{+}$ partner might be within reach. This, in turn, would reveal the spins of the ${P}_{c}(4440)$ and ${P}_{c}(4457)$ pentaquarks, providing a highly nontrivial test of heavy-quark symmetry and the molecular nature of the pentaquarks. Furthermore, the molecular interpretation of the hidden-charm pentaquarks implies the existence of a total of ten triply charmed dibaryons as ${\mathrm{\ensuremath{\Xi}}}_{cc}^{(*)}{\mathrm{\ensuremath{\Sigma}}}_{c}^{(*)}$ molecules, which, if confirmed in the lattice, will largely expand our understanding of the nonperturbative strong interaction in the heavy-quark sector.

Abstract: We analyze the precise data obtained by the CMD-3 experiment on the ${e}^{+}{e}^{\ensuremath{-}}$ annihilation into two charged kaons in the vicinity of the $\ensuremath{\phi}$ peak. A perfect fit is obtained only if a pole on the real axis below the reaction threshold is assumed. This can be interpreted as proof of the existence of the 2p state of kaonium, a compound of ${K}^{+}$ and ${K}^{\ensuremath{-}}$. The BABAR Collaboration data on the same process supports this conclusion and, in addition, points to the strong interaction as a dominant source of the binding energy. The possibility of discovering 2p kaonium in the ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$ process is discussed. The 2p state of ${K}^{0}$-onium is indicated on the basis of the CMD-3 ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{K}_{S}^{0}{K}_{L}^{0}$ data.

Abstract: Light can be strongly confined in subwavelength spatial regions through the interaction with plasmons, the collective electronic modes appearing in metals and semiconductors. This confinement, which is particularly important in the terahertz spectral region, amplifies light-matter interaction and provides a powerful mechanism for efficiently generating nonlinear optical phenomena. These effects are particularly relevant in graphene and topological insulators, where massless Dirac fermions show a naturally nonlinear optical behavior in the terahertz range. The strong interaction scenario has been considered so far from the point of view of light. In this Letter, we investigate instead the effect of strong interaction on the plasmon itself. In particular, we will show that Dirac plasmons in ${\mathrm{Bi}}_{2}{\mathrm{Se}}_{3}$ topological insulator are strongly renormalized when excited by high-intensity terahertz radiation by displaying a huge red-shift down to 60% of its characteristic frequency. This opens the road towards tunable terahertz nonlinear optical devices based on topological insulators.

Abstract: The Λ_{c}^{+}K^{-} mass spectrum is studied with a data sample of pp collisions at a center-of-mass energy of 13 TeV corresponding to an integrated luminosity of 5.6 fb^{-1} collected by the LHCb experiment. Three Ξ_{c}^{0} states are observed with a large significance and their masses and natural widths are measured to be m[Ξ_{c}(2923)^{0}]=2923.04±0.25±0.20±0.14 MeV, Γ[Ξ_{c}(2923)^{0}]=7.1±0.8±1.8 MeV, m[Ξ_{c}(2939)^{0}]=2938.55±0.21±0.17±0.14 MeV, Γ[Ξ_{c}(2939)^{0}]=10.2±0.8±1.1 MeV, m[Ξ_{c}(2965)^{0}]=2964.88±0.26±0.14±0.14 MeV, Γ[Ξ_{c}(2965)^{0}]=14.1±0.9±1.3 MeV, where the uncertainties are statistical, systematic, and due to the limited knowledge of the Λ_{c}^{+} mass. The Ξ_{c}(2923)^{0} and Ξ_{c}(2939)^{0} baryons are new states. The Ξ_{c}(2965)^{0} state is in the vicinity of the known Ξ_{c}(2970)^{0} baryon; however, their masses and natural widths differ significantly.

Abstract: The ratio of the Bs0 and B+ fragmentation fractions fs and fu is studied with Bs0→J/ψφ and B+→J/ψK+ decays using data collected by the LHCb experiment in proton-proton collisions at 7, 8, and 13 TeV center-of-mass energies. The analysis is performed in bins of B-meson momentum, longitudinal momentum, transverse momentum, pseudorapidity, and rapidity. The fragmentation-fraction ratio fs/fu is observed to depend on the B-meson transverse momentum with a significance of 6.0σ. This dependency is driven by the 13 TeV sample (8.7σ), while the results for the other collision energies are not significant when considered separately. Furthermore, the results show a 4.8σ evidence for an increase of fs/fu as a function of collision energy.

Abstract: Ratios of isospin amplitudes in hadron decays are a useful probe of the interplay between weak and strong interactions and allow searches for physics beyond the standard model. We present the first results on isospin amplitudes in b-baryon decays, using data corresponding to an integrated luminosity of 8.5 fb-1, collected with the LHCb detector in pp collisions at center of mass energies of 7, 8, and 13 TeV. The isospin amplitude ratio |A1(Λb0→J/ψς0)/A0(Λb0→J/ψΛ)|, where the subscript on A indicates the final-state isospin, is measured to be less than 1/21.8 at 95% confidence level. The Cabibbo suppressed Ξb0→J/ψΛ decay is observed for the first time, allowing for the measurement |A0(Ξb0→J/ψΛ)/A1/2(Ξb0→J/ψΞ0)|=0.37±0.06±0.02, where the uncertainties are statistical and systematic, respectively.

24. Physics of Nuclei: Key Role of an Emergent Symmetry

Abstract: Exact symmetry and symmetry-breaking phenomena play a key role in providing a better understanding of the physics of many-particle systems, from quarks and atomic nuclei, to molecules and galaxies. In atomic nuclei, exact and dominant symmetries such as rotational invariance, parity, and charge independence have been clearly established. However, even when these symmetries are taken into account, the structure of nuclei remains illusive and only partially understood, with no additional symmetries immediately evident from the underlying nucleon-nucleon interaction. Here, we show through ab initio large-scale nuclear structure calculations that the special nature of the strong nuclear force determines additional highly regular patterns in nuclei that can be tied to an emergent approximate symmetry. We find that this symmetry is remarkably ubiquitous, regardless of its particular strong interaction heritage, and mathematically tracks with a symplectic group. Specifically, we show for light to intermediate-mass nuclei that the structure of a nucleus, along with its low-energy excitations, respects symplectic symmetry at about 70-80% level, unveiling the predominance of only a few equilibrium shapes, deformed or not, with associated vibrations and rotations. This establishes the symplectic symmetry as a remarkably good symmetry of the strong nuclear force, in the low-energy regime. This may have important implications to studies in astrophysics and neutrino physics that rely on nuclear structure information, especially where experimental measurements are incomplete or not available. A very important practical advantage is that this new symmetry can be utilized to dramatically reduce computational resources required in ab initio large-scale nuclear structure modeling. This, in turn, can be used to pioneer predictions, e.g., for short-lived isotopes along various nucleosynthesis pathways., Comment: 6 pages, 4 figures

Abstract: The momentum correlation functions of baryon pairs, which reflects the baryon-baryon interaction at low energies, are investigated for multistrangeness pairs (ΩΩ and NΩ) produced in relativistic heavy-ion collisions. We calculate the correlation functions based on an expanding source model constrained by single-particle distributions. The interaction potentials are taken from those obtained from recent lattice QCD calculations at nearly physical quark masses. Experimental measurements of these correlation functions for different system sizes will help to disentangle the strong interaction between baryons and to unravel the possible existence of strange dibaryons.

26. Next-to-leading order Balitsky-Kovchegov equation beyond large Nc

Author: Lappi, Tuomas, Mäntysaari, Heikki, and Ramnath, Andrecia
Subjects: particle interactions, strong interaction, quantum chromodynamics, hiukkasfysiikka
Abstract: We calculate finite-Nc corrections to the next-to-leading order (NLO) Balitsky-Kovchegov (BK) equation. We find analytical expressions for the necessary correlators of six Wilson lines in terms of the two-point function using the Gaussian approximation. In a suitable basis, the problem reduces from the diagonalization of a six-by-six matrix to the diagonalization of a three-by-three matrix, which can easily be done analytically. We study numerically the effects of these finite-Nc corrections on the NLO BK equation. In general, we find that the finite-Nc corrections are smaller than the expected 1/N2c∼10%. The corrections may be large for individual correlators, but have less of an influence on the shape of the amplitude as a function of the dipole size. They have an even smaller effect on the evolution speed as a function of rapidity. peerReviewed

27. DK , DDK , and DDDK molecules–understanding the nature of the Ds0*(2317)

Abstract: The $DK$ interaction is strong enough to form a bound state, the ${D}_{s0}^{*}(2317)$. This in turn begs the question of whether there are bound states composed of several charmed mesons and a kaon. Previous calculations indicate that the three-body $DDK$ system is probably bound, where the quantum numbers are ${J}^{P}={0}^{\ensuremath{-}}$, $I=\frac{1}{2}$, $S=1$ and $C=2$. The minimum quark content of this state is $cc\overline{q}\overline{s}$ with $q=u$, $d$, which means that, if discovered, it will be an explicitly exotic tetraquark. In the present work. we apply the Gaussian expansion method to study the $DDDK$ system and show that it binds as well. The existence of these three and four body states is rather robust with respect to the $DD$ interaction and subleading (chiral) corrections to the $DK$ interaction. If these states exist, it is quite likely that their heavy quark symmetry counterparts exist as well. These three-body $DDK$ and four-body $DDDK$ molecular states could be viewed as counterparts of atomic nuclei, which are clusters of nucleons bound by the residual strong force, or chemical molecules, which are clusters of atoms bound by the residual electromagnetic interaction.

Abstract: By performing density functional theory-based first-principles calculations, the formation of a thin monolayer structure, namely InSeF, via fluorination of monolayer InSe is predicted. It is shown that strong interaction of F and In atoms leads to the detachment of In-Se layers in monolayer InSe and 1T-like monolayer InSeF structure is formed. Monolayer InSeF is found to be dynamically stable in terms of its phonon band dispersions. In addition, its Raman spectrum is shown to exhibit totally distinctive features as compared to monolayer InSe. The electronic band dispersions reveal that monolayer InSeF is a direct gap semiconductor whose valence and conduction band edges reside at the $\mathrm{\ensuremath{\Gamma}}$ point. Moreover, the orientation-dependent linear elastic properties of monolayer InSeF are investigated in terms of the in-plane stiffness and Poisson ratio. It is found that monolayer InSeF displays strong in-plane anisotropy in elastic constants and it is slightly softer material as compared to monolayer InSe. Overall, it is proposed that a thin, direct gap semiconducting monolayer InSeF can be formed by full fluorination of monolayer InSe as a new member of the two-dimensional family.

Abstract: The magnon dispersion of ferromagnetic SrRuO_{3} was studied by inelastic neutron scattering experiments on single crystals as a function of temperature. Even at low temperature the magnon modes exhibit substantial broadening pointing to strong interaction with charge carriers. We find an anomalous temperature dependence of both the magnon gap and the magnon stiffness, which soften upon cooling in the ferromagnetic phase. Both effects trace the temperature dependence of the anomalous Hall effect and can be attributed to the impact of Weyl points, which results in the same relative renormalization in the spin stiffness and magnon gap.

Abstract: An electromagnetic plasma mode has been discovered in the hybrid system formed by a highly conductive gate strip placed in proximity to the two-dimensional electron system. The plasmon mode propagates along the gate strip with no potential nodes present in transverse direction. Its spectrum combines characteristic features of both gated and ungated two-dimensional plasmons. The plasma excitation has been found to exhibit anomalously strong interaction with light.

Abstract: This review covers the modern era of experimental kaonic atom studies, encompassing 20 years of activity, defined by breakthroughs in technological developments which allowed performing a series of long-awaited precision measurements. Kaonic atoms are atomic systems where an electron is replaced by a negatively charged kaon, containing the strange quark, which interacts in the lowest orbits with the nucleus also by the strong interaction. As a result, their study offers the unique opportunity to perform experiments equivalent to scattering at vanishing relative energy. This allows one to study the strong interaction between the antikaon and the nucleon or the nucleus “at threshold,” namely, at zero relative energy, without the need of ad hoc extrapolation to zero energy, as in scattering experiments. The fast progress achieved in performing precision light kaonic atom experiments, which also solved long-pending inconsistencies with theoretical calculations generated by old measurements, relies on the development of novel cryogenic targets, x-ray detectors, and the availability of pure and intense charged kaon beams, which propelled an unprecedented progress in the field. Future experiments, based on new undergoing technological developments, will further boost the kaonic atom studies, thus fostering a deeper understanding of the low-energy strong interaction extended to the second family of quarks.

Abstract: International audience; The parity-violating neutron spin rotation in He4 is studied at vanishing incident neutron energy limit. Calculations have been realized by solving five-body Faddeev-Yakubovsky equations in configuration space employing modern strong-interaction Hamiltonian based on chiral perturbation theory including three-nucleon force. Parity-violating nucleon-nucleon interaction of the Desplanques, Donoghue, and Holstein model is employed. An implication of the recent theoretical large-Nc estimation of weak couplings [Phillips , Phys. Rev. Lett. 114, 062301 (2015)PRLTAO0031-900710.1103/PhysRevLett.114.062301] is also discussed.

Abstract: Recent experimental progress has led to the detection of many new hadrons. Very recently, the LHCb Collaboration announced the observation of two new ${\mathrm{\ensuremath{\Sigma}}}_{b}(6097{)}^{\ifmmode\pm\else\textpm\fi{}}$ states in the ${\mathrm{\ensuremath{\Lambda}}}_{b}^{0}{\ensuremath{\pi}}^{\ifmmode\pm\else\textpm\fi{}}$ invariant mass distribution, which are considered to be the excited states of the ground-state ${\mathrm{\ensuremath{\Sigma}}}_{b}^{(*)}$ baryon. Although almost all of the ground-state baryons have been observed, the fact that only a limited number of excited states have been observed makes them intriguing. Understanding the properties of the excited baryons would improve our knowledge about the strong interaction, as well as the nature and internal structures of these baryons. To specify the quantum numbers of the ${\mathrm{\ensuremath{\Sigma}}}_{b}(6097{)}^{\ifmmode\pm\else\textpm\fi{}}$ states, we analyze their strong decays to ${\mathrm{\ensuremath{\Lambda}}}_{b}^{0}$ and ${\ensuremath{\pi}}^{\ifmmode\pm\else\textpm\fi{}}$ within the light-cone QCD sum rules formalism. To this end, they are considered as possible $1P$ or $2S$ excitations of either the ground-state ${\mathrm{\ensuremath{\Sigma}}}_{b}$ baryon with $J=\frac{1}{2}$ or the ${\mathrm{\ensuremath{\Sigma}}}_{b}^{*}$ baryon with $J=\frac{3}{2}$, and their corresponding masses are calculated. The results of the analyses indicate that the ${\mathrm{\ensuremath{\Sigma}}}_{b}(6097{)}^{\ifmmode\pm\else\textpm\fi{}}$ baryons are excited $1P$ baryons with quantum numbers ${J}^{P}={\frac{3}{2}}^{\ensuremath{-}}$.

34. Millicharged scalar fields, massive photons and the breaking of SU(3)C×U(1)EM

Abstract: Under the assumption that the current epoch of the Universe is not special, i.e., is not the final state of a long history of processes in particle physics, the cosmological fate of $SU(3{)}_{C}\ifmmode\times\else\texttimes\fi{}U(1{)}_{\mathrm{EM}}$ is investigated. Spontaneous symmetry breaking of $U(1{)}_{\mathrm{EM}}$ at the temperature of the Universe today is carried out. The charged scalar field ${\ensuremath{\phi}}_{\mathrm{EM}}$ which breaks the symmetry is found to be ruled out for the charge of the electron, $q=e$. Scalar fields with millicharges are viable and limits on their masses and charges are found to be $q\ensuremath{\lesssim}{10}^{\ensuremath{-}3}e$ and ${m}_{{\ensuremath{\phi}}_{\mathrm{EM}}}\ensuremath{\lesssim}{10}^{\ensuremath{-}5}\text{ }\text{ }\mathrm{eV}$. Furthermore, it is possible that $U(1{)}_{\mathrm{EM}}$ has already been broken at temperatures higher than $T=2.7\text{ }\text{ }\mathrm{K}$ given the nonzero limits on the mass of the photon. A photon mass of ${m}_{\ensuremath{\gamma}}={10}^{\ensuremath{-}18}\text{ }\text{ }\mathrm{eV}$, the current upper limit, is found to require a spontaneous symmetry breaking scalar mass of ${m}_{{\ensuremath{\phi}}_{\mathrm{EM}}}\ensuremath{\sim}{10}^{\ensuremath{-}13}\text{ }\text{ }\mathrm{eV}$ with charge $q={10}^{\ensuremath{-}6}e$, well within the allowed parameter space of the model. Finally, the cosmological fate of the strong interaction is studied. $SU(3{)}_{C}$ is tested for complementarity in which the confinement phase of $\mathrm{QCD}+$ colored scalars is equivalent to a spontaneously broken $SU(3)$ gauge theory. If complementarity is not applicable, $SU(3{)}_{C}$ has multiple symmetry breaking paths with various final symmetry structures. The stability of the colored vacuum at finite temperature in this scenario is nonperturbative and a definitive statement on the fate of $SU(3{)}_{C}$ is left open. Cosmological implications for the metastability of the vacua---electromagnetic, color, and electroweak---are discussed.

Abstract: We investigate the behavior of the doubly heavy spin$-3/2$ baryons in cold nuclear matter. In particular, we study the variations of the spectroscopic parameters of the ground state $\Xi^*_{QQ'}$ and $\Omega^*_{QQ'}$ particles, with $ Q $ and $ Q' $ being $b $ or $ c $ quark, with respect to the changes in the density of the nuclear medium. We find the shifts on the parameters under question at saturation medium density compared to their vacuum values. It is observed that the parameters of the $\Xi^*_{QQ'}$ states containing two heavy quarks and one up or down quark are affected by the medium, considerably. The parameters of the $\Omega^*_{QQ'}$ states containing two heavy quarks and one strange quark, however, do not show any sensitivity to the density of the cold nuclear medium. We also discuss the variations of the vector self-energy at each channel with respect to the changes in the density. The negative shifts in the mass of $\Xi^*_{QQ'}$ states due to nucleons in the medium can be used to study the doubly heavy baryons' interactions with the nucleons. The results obtained can also be used in analyses of the results of the future in-medium experiments., Comment: 24 Pages, 5 Figures and 3 Tables

Abstract: A Falicov-Kimball model which thermodynamically reduces the local Coulomb interaction of particles to attraction or repulsion is studied within the dynamical mean-field theory. In the strong interaction regime a fractionalization of particles into charge and spin objects, the physical properties of which are different from the whole particles, is observed in both high- and low-temperature phases. At high temperature and strong interaction the single-particle density of states opens an excitation gap, but the charge compressibility and the spin susceptibility exhibit the features of gapless excitations. The low-temperature phase has a long-range order, and the single-particle spectra are always gapped, while the charge and spin excitations are gapless in the strong interaction regime. In the fractionalized long-range ordered phase both the charge compressibility and the spin susceptibility are universal scaling functions of temperature.

Abstract: We develop a rigorous theory for nanophotonic cooperative spontaneous emission of an ensemble of quantum emitters near matter, which also incorporates absorption. Such theory is highly requested since one should expect that in the field of nanophotonics the close-by emitters will emit cooperatively simultaneously with strong interaction with the exotic metamaterial complex dielectric function. The closed-form model developed here considers the buildup both of interemitter correlation over time through emitter transitions via the mutual field and of geometry-induced spatial correlation. The presence of matter alters the local density of states (LDOS), resulting in modified decay rate and emission intensity for the entire ensemble relative to values of spontaneous emission in free space. The superradiant total emission is separable into a quantum-mechanical time-dependent part and a classical space-dependent part, both being functions of the LDOS. Two distinct radiative emitter--far-field coupling mechanisms, which together account for the superradiant emission, are obtained---the coupling of every individual emitter with the far field and the coupling of emitter pairs to the far field. The calculations for superradiating emitters near silver and near-zero epsilon (NZE) materials were performed with the following results: the silver sphere augments the superradiant far-field intensity and rate by up to 400 and 1000%, respectively, while the NZE sphere enhances the far-field intensity and rate of the superradiance by approximately 1400 and 400%, respectively.

Abstract: Entanglement suppression in the strong interaction $S$-matrix is shown to be correlated with approximate spin-flavor symmetries that are observed in low-energy baryon interactions, the Wigner $SU(4)$ symmetry for two flavors and an $SU(16)$ symmetry for three flavors. We conjecture that dynamical entanglement suppression is a property of the strong interactions in the infrared, giving rise to these emergent symmetries and providing powerful constraints on the nature of nuclear and hypernuclear forces in dense matter., Comment: 6 pages, 5 pages supplemental, 4 figures

Abstract: The wave numbers and efficiencies of the first-order lattice vibrational modes of the isomorphous solid solutions of $\mathrm{LiNb}{\mathrm{O}}_{3}\text{\ensuremath{-}}\mathrm{LiTa}{\mathrm{O}}_{3}$ have been studied by Raman and infrared spectroscopies. The substitution of niobium by tantalum induces a continuous shift of wave numbers and intensities of phonon modes indicating a one-phonon behavior. In general, the wave numbers of vibrations at low frequencies $(l325\phantom{\rule{0.16em}{0ex}}\mathrm{c}{\mathrm{m}}^{\ensuremath{-}1})$ soften with the increased atomic mass. The frequencies of most of the high-frequency modes increase with the Ta/Nb ratio owing to enhanced force constants. A qualitative relation between the shift of transverse and longitudinal modes in the solid solutions has been found on the basis of an overlap matrix. The exceptional softening of several high-frequency modes with the replacement of Nb by Ta originates from the strong interaction of these modes with modes at low frequencies according to the overlap matrix. The intensities of the Raman modes are strongly modulated by the electronic properties with Ta/Nb substitution and this emphasizes their role in the physical properties of $\mathrm{LiNb}{\mathrm{O}}_{3}$ and $\mathrm{LiTa}{\mathrm{O}}_{3}$.

Abstract: We investigate the time-optimal control of the purification of a qubit interacting with a structured environment, consisting of a strongly coupled two-level defect in interaction with a thermal bath. On the basis of a geometric analysis, we show for weak and strong interaction strengths that the optimal control strategy corresponds to a qubit in resonance with the reservoir mode. We investigate under which conditions qubit coherence and correlation between the qubit and the environment can speed up the control process.

Abstract: We report on the first femtoscopic measurement of baryon pairs, such as p-p, p-Λ, and Λ-Λ, measured by ALICE at the Large Hadron Collider (LHC) in proton-proton collisions at s=7TeV. This study demonstrates the feasibility of such measurements in pp collisions at ultrarelativistic energies. The femtoscopy method is employed to constrain the hyperon-nucleon and hyperon-hyperon interactions, which are still rather poorly understood. A new method to evaluate the influence of residual correlations induced by the decays of resonances and experimental impurities is hereby presented. The p-p, p-Λ, and Λ-Λ correlation functions were fitted simultaneously with the help of a new tool developed specifically for the femtoscopy analysis in small colliding systems: Correlation Analysis Tool using the Schrodinger equation (CATS). Within the assumption that in pp collisions the three particle pairs originate from a common source, its radius is found to be equal to r0=1.125±0.018(stat)−0.035+0.058(syst) fm. The sensitivity of the measured p-Λ correlation is tested against different scattering parameters, which are defined by the interaction among the two particles, but the statistics is not sufficient yet to discriminate among different models. The measurement of the Λ-Λ correlation function constrains the phase space spanned by the effective range and scattering length of the strong interaction. Discrepancies between the measured scattering parameters and the resulting correlation functions at LHC and RHIC energies are discussed in the context of various models.

Abstract: We consider decays of the hidden charm LHCb pentaquarks in the hadrocharmonium and molecular scenarios. In both pictures the LHCb pentaquarks are essentially nonrelativistic bound states. We develop a semirelativistic framework for calculation of the partial decay widths that allows the final particles to be relativistic. Using this approach we calculate the decay widths in the hadrocharmonium and molecular pictures. Molecular hidden charm pentaquarks are constructed as loosely bound states of charmed and anticharmed hadrons. Calculations show that molecular pentaquarks decay predominantly into states with open charm. Strong suppression of the molecular pentaquark decays into states with hidden charm is qualitatively explained by a relatively large size of the molecular pentaquark. The decay pattern of hadrocharmonium pentaquarks that are interpreted as loosely bound states of excited charmonium ψ′ and nucleons is quite different. This time dominate decays into states with hidden charm, but suppression of the decays with charm exchange is weaker than in the respective molecular case. The weaker suppression is explained by a larger binding energy and respectively smaller size of the hadrocharmonium pentaquarks. These results combined with the experimental data on partial decay widths could allow to figure out which of the two theoretical scenarios for pentaquarks (if either) is chosen by nature.

In addition, we calculate its three-body decay width into KπΞ. It is shown that the so-obtained total decay width is in fair agreement with the experimental data. We compare our results with those of other recent studies and highlight the differences among them.

Abstract: A theoretical model of the reactions ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{K}^{+}{K}^{\ensuremath{-}}\ensuremath{\gamma}$ and ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{K}^{0}\overline{{K}^{0}}\ensuremath{\gamma}$ has been derived. The strong interaction between kaons is taken into account using a general form of the $K\overline{K}$ scattering amplitude. It is shown that some models formulated in the past are particular cases of the present approach. The formulas for the $K\overline{K}$ effective mass dependence of the differential cross section as well as for the angular kaon and photon distributions and for the branching fractions of the $\ensuremath{\phi}(1020)\ensuremath{\rightarrow}{K}^{+}{K}^{\ensuremath{-}}\ensuremath{\gamma}$ and $\ensuremath{\phi}(1020)\ensuremath{\rightarrow}{K}^{0}\overline{{K}^{0}}\ensuremath{\gamma}$ decays have been obtained. We present numerical results for the functions entering into transition amplitudes, $K\overline{K}$ effective mass distributions, total cross sections, and branching fractions. Finally, the model is generalized to treat other reactions with two pseudoscalar mesons accompanying a photon in the final state.

Abstract: The nonmesonic weak decay of the doubly strange hypernucleus $_{\mathrm{\ensuremath{\Lambda}}\mathrm{\ensuremath{\Lambda}}}^{\phantom{\rule{1em}{0ex}}6}\mathrm{He}$ is studied within a model that considers the exchange of pseudoscalar and vector mesons. Special attention is paid to quantifying the strong interaction effects, focusing on the interaction among the two $\mathrm{\ensuremath{\Lambda}}$ hyperons that induces novel weak transitions, whereby $\mathrm{\ensuremath{\Lambda}}\mathrm{\ensuremath{\Lambda}}$, $\mathrm{\ensuremath{\Xi}}N$, and $\mathrm{\ensuremath{\Sigma}}\mathrm{\ensuremath{\Sigma}}$ states decay into a hyperon-nucleon pair. The initial strangeness $\ensuremath{-}2$ wave function is obtained from the solution of a $G$-matrix equation with the input of realistic strong baryon-baryon potentials, while the final hyperon-nucleon wave functions are derived analogously from a microscopic $T$-matrix calculation. The new $\mathrm{\ensuremath{\Lambda}}\mathrm{\ensuremath{\Lambda}}\ensuremath{\rightarrow}YN$ decay rate studied in this work, ${\mathrm{\ensuremath{\Gamma}}}_{\mathrm{\ensuremath{\Lambda}}n}+{\mathrm{\ensuremath{\Gamma}}}_{{\mathrm{\ensuremath{\Sigma}}}^{0}n}+{\mathrm{\ensuremath{\Gamma}}}_{{\mathrm{\ensuremath{\Sigma}}}^{\ensuremath{-}}p}$, represents 3--4% of the total one-baryon-induced nonmesonic decay and is remarkably affected by strong interaction effects. In particular, the relative importance of the partial decay rates encoded in the ratio ${\mathrm{\ensuremath{\Gamma}}}_{\mathrm{\ensuremath{\Lambda}}n}/({\mathrm{\ensuremath{\Gamma}}}_{{\mathrm{\ensuremath{\Sigma}}}^{0}n}+{\mathrm{\ensuremath{\Gamma}}}_{{\mathrm{\ensuremath{\Sigma}}}^{\ensuremath{-}}p})$ gets inverted when the mixing to $\mathrm{\ensuremath{\Xi}}N$ states is incorporated in the initial correlated $\mathrm{\ensuremath{\Lambda}}\mathrm{\ensuremath{\Lambda}}$ wave function. This sensitivity can be used experimentally to learn about the strong interaction in the strangeness $\ensuremath{-}2$ sector.

47. NΩ interaction: Meson exchanges, inelastic channels, and quasibound state

Abstract: Based on a baryon-baryon interaction model with meson exchanges, we investigate the origin of the strong attraction in the $N \Omega ( {}^{5}S_{2} )$ interaction, which was indicated by recent lattice QCD simulations. The long range part of the potential is constructed by the conventional mechanisms, the exchanges of the $\eta$ meson and of the correlated two mesons in the scalar-isoscalar channel, denoted by "$\sigma$" in the literature. The short range part is represented by the contact interaction. We find that the meson exchanges do not provide sufficient attraction. This means that most of the attraction is attributed to the short range contact interaction. We then evaluate the effect of the coupled channels to the $N \Omega ( {}^{5}S_{2} )$ interaction. We find that, while the $D$-wave mixing of the $N \Omega$ channel is negligible, the inelastic $\Lambda \Xi$, $\Sigma \Xi$, and $\Lambda \Xi (1530)$ channels via the $K$ meson exchange give the attraction of the $N \Omega ( {}^{5}S_{2} )$ interaction to the same level with the elastic meson exchanges. Although the elimination of these channels induces the energy dependence of the single-channel $N \Omega$ interaction, this effect is not significant. With the present model parameters fitted to reproduce the scattering length of the HAL QCD result of the nearly physical quark masses, we obtain the $N \Omega ( {}^{5}S_{2} )$ quasibound state with its eigenenergy $2611.3 - 0.7 i$ MeV, which corresponds to the binding energy $0.1$ MeV and width $1.5$ MeV for the decay to the $\Lambda \Xi$ and $\Sigma \Xi$ channels. From the analysis of the spatial structure and the compositeness, the quasibound state is shown to be the molecular state of $N\Omega$. We also construct an equivalent local potential for the $N \Omega ( {}^{5}S_{2} )$ system which is useful for various applications., Comment: 22 pages, 17 eps figures

Abstract: The recent precision measurement of the relative yield of $D^+D^-$ and $D^0 \bar D^0$ meson pairs at the $\psi(3770)$ peak in $e^+e^-$ annihilation is about 3.7 sigma away from a straightforward theoretical estimate. It is argued that combined with an even more significant deviation of similar ratio for the $B$ mesons at the $\Upsilon(4S)$ peak, this provides an insight into the structure of heavy mesons and requires both a form factor, corresponding to their finite `size', and a strong interaction between the mesons mesons in the isovector state $I^G(J^P) = 1^+(1^-)$. It is also argued that the data for the $D$ and $B$ mesons are possibly compatible with the heavy quark limit of the same meson-antimeson strong interaction in both systems.

Abstract: In this work, we study strong and radiative decays of S-wave DΞ molecular state, which is related to the Ωc* states newly observed at LHCb. The coupling between the DΞ molecular state and its constituents D and Ξ is calculated by using the compositeness condition. With the obtained coupling, the partial decay widths of the DΞ molecular state into the Ξc+K-, Ξc′+K-, and Ωc*(2695)γ final states through hadronic loop are calculated with the help of the effective Lagrangians. By comparison with the LHCb observation, the current results of total decay width support the Ωc*(3119) or Ωc*(3050) as DΞ molecule while the decay width of the Ωc*(3000), Ωc*(3066), and Ωc*(3090) can not be well reproduced in the molecular state picture. The partial decay widths are also presented and helpful to further understand the internal structures of Ωc*(3119) and Ωc*(3050).

Abstract: Strong interaction of a terahertz (THz) wave with excitons induces nonperturbative optical effects such as Rabi splitting and high-order sideband generation. Here, we investigated coherent properties of THz-induced sideband emissions from GaAs/AlGaAs multiquantum wells. With increasing THz electric field, optical susceptibility of the THz-dressed exciton shows a redshift with spectral broadening and extraordinary phase shift. This implies that the field ionization of the $1s$ exciton modifies the THz-dressed exciton in the nonperturbative regime.
