1. Systematics of neutron emission

Author: Delion, D. S. and Ghinescu, S.
Subjects: Nuclear Theory
Abstract: Neutron physics is one of the oldest brach of the experimental nuclear physics, but the investigation of the spontaneous neutron emission from the ground state along the neutron dripline is still at its beginning, in spite of the crucial importance for nuclear astrophysics. The proton dripline is much better investigated and a systematics of spontaneous proton half lives is available in terms of the Coulomb parameter, characterizing the outgoing irregular Coulomb wave. Our purpose is to propose a similar systematics of spontaneous neutron half lives, but in terms of the nuclear reduced radius, characterizing the "neutral" spherical irregular Neumann wave., Comment: 4 pages, 3 figures, 38 references

2. Self-consistent calculations for atomic electron capture

Author: Sevestrean, V. A., Niţescu, O., Ghinescu, S., and Stoica, S.
Subjects: Nuclear Theory, Physics - Atomic Physics
Abstract: We present a comprehensive investigation of electron capture (EC) ratios spanning a broad range of atomic numbers. The study employs a self-consistent computational method that incorporates electron screening, electron correlations, overlap and exchange corrections, as well as shake-up and shake-off atomic effects. The electronic wave functions are computed with the Dirac-Hartree-Fock-Slater (DHFS) method, chosen following a systematic comparison of binding energies, atomic relaxation energies and Coulomb amplitudes against other existing methods and experimental data. A novel feature in the calculations is the use of an energy balance employing atomic masses, which avoids approximating the electron total binding energy and allows a more precise determination of the neutrino energy. This leads to a better agreement of our predictions for capture ratios in comparison with the experimental ones, especially for low-energy transitions. We expand the assessment of EC observables uncertainties by incorporating atomic relaxation energy uncertainties, in contrast to previous studies focusing only on Q-value and nuclear level energies. Detailed results are presented for nuclei of practical interest in both nuclear medicine and exotic physics searches involving liquid Xenon detectors ($^{67}\mathrm{Ga}$, $^{111}\mathrm{In}$, $^{123}\mathrm{I}$, $^{125}\mathrm{I}$ and $^{125}\mathrm{Xe}$). Our study can be relevant for astrophysical, nuclear, and medical applications., Comment: 16 pages, 9 figures, 4 tables

Subjects: High Energy Physics - Experiment, Physics - Instrumentation and Detectors
Abstract: A timely and long-term programme of kaon decay measurements at a new level of precision is presented, leveraging the capabilities of the CERN Super Proton Synchrotron (SPS). The proposed programme is firmly anchored on the experience built up studying kaon decays at the SPS over the past four decades, and includes rare processes, CP violation, dark sectors, symmetry tests and other tests of the Standard Model. The experimental programme is based on a staged approach involving experiments with charged and neutral kaon beams, as well as operation in beam-dump mode. The various phases will rely on a common infrastructure and set of detectors., Comment: Letter of Intent submitted to CERN SPSC. Address all correspondence to hike-eb@cern.ch

4. Semi-microscopic theory of two proton emission

Author: Ghinescu, S. A. and Delion, D. S.
Subjects: Nuclear Theory
Abstract: We propose a semi-microscopic model for the simultaneous emission of two protons. This model has the advantage of avoiding certain technical aspects of a fully microscopic 3-body framework, while also allowing the investigation of the influence of proton pairing on the total lifetime of the decaying nucleus. Thus, we use the standard singlet two-proton wave function on the nuclear surface, provided by the Bardeen-Cooper-Schrieffer (BCS) approach, as a boundary condition for the propagator operator. Our model allows for the estimation of all quantities related to the $2p$ emission process, since it provides the 3-body wave function over most of the domain. We show that reasonable agreement with experimental values can be reached by varying the $pp$ pairing strength outside the nucleus in an interval close to the "bare" singlet value.

5. Investigation of the Lorentz invariance violation in two-neutrino double-beta decay

Author: Ghinescu, S. A., Nitescu, O., and Stoica, S.
Subjects: Nuclear Theory
Abstract: We make a comprehensive investigation of the Lorentz invariance violation (LIV) effects that may occur in two-neutrino double-beta ($2\nu\beta\beta$) decay for all the experimentally interesting nuclei. We deduce the formulas for the LIV deviations and provide single and summed energy electron spectra and angular correlation between electrons with and without LIV contributions, to be used for constraining the LIV coefficient $\mathring{a}_{\text{of}}^{(3)}$. First, we confirm the shifting of the electron spectra to higher electron energies due to LIV for all nuclei. Next, we analyze other LIV signatures that can be used in LIV investigations. Thus, from the comparison of the electron and angular correlation spectra calculated with the inclusion of the LIV contributions, with their standard forms, information can be obtained about the strength versus observability of the LIV effects in the current experimental statistics. Then, we present the alternative method of constraining $\mathring{a}_{\text{of}}^{(3)}$ from the measurement of the angular correlation coefficient and estimate the statistics that different double-beta decay experiments should reach to constrain the LIV coefficient at the level of the current beta decay experiments. We hope that our work will improve the theoretical support and further stimulate the search for LIV in double-beta decay.

6. Two-proton emission systematics

Author: Delion, D. S. and Ghinescu, S. A.
Subjects: Nuclear Theory
Abstract: The simultaneous emission of two protons is an exotic and complex three-body process. It is very important for experimental groups investigating the nuclear stability on the proton drip line to have a simple rule predicting the two-proton decay widths with a reasonable accuracy for transitions between ground as well as excited states in terms of relevant physical variables. In spite of its complexity, we show that the two-proton emission process obeys similar rules as for binary emission processes like proton, alpha and heavy cluster decays. It turns out that the logarithm of the decay width, corrected by the centrifugal barrier, linearly depends upon the Coulomb parameter within one order of magnitude. On the other hand, the universal linear dependence with a negative slope between the logarithm of the reduced width and the fragmentation potential, valid for any kind of binary decay process, is also fulfilled for the two-proton emission with a relative good accuracy. As a consequence of pairing correlations the two protons are simultaneously emitted from a singlet paired state. We evidence that indeed one obtains a linear dependence between the logarithm of the reduced width and pairing gap within a factor of two, giving a good predictive power to this law. It turns out that the diproton and alpha-cluster formation probabilities have similar patterns versus the pairing gap, while in the one-proton case one has a quasi-constant behavior., Comment: 5 pages, 4 figures, 2 tables, 36 references

7. Semiclassical propagator approach for emission processes. I. Two body non-relativistic case

Author: Ghinescu, S. A. and Delion, D. S.
Subjects: Nuclear Theory
Abstract: We compare the coupled channels procedure to the semiclassical approach to describe two-body emission processes, in particular $\alpha$-decay, from deformed nuclei within the propagator method. We express the scattering amplitudes in terms of a propagator matrix, describing the effect of the deformed field, multiplied by the ratio between internal wave function components and irregular Coulomb waves. In the spherical case the propagator becomes diagonal and scattering amplitudes acquire the well-known form. We describe a more rigorous formulation of the 3D semiclassical approach, corresponding to deformed potentials, which leads to the exact results and we also compare them with the much simpler expressions given by the Angular Wentzel-Krames-Brillouin (AWKB) and Linearized WKB (LWKB) with its approximation, known as Fr\"oman WKB (FWKB) method. We will show that LWKB approach is closer than AWKB to the exact coupled-channels formalism. An analysis of alpha-emission from ground states of even-even nuclei evidences the important role played by deformation upon the channel decay widths.

8. Probing Lorentz violation in $2\nu\beta\beta$ using single electron spectra and angular correlations

Author: Nitescu, O. V., Ghinescu, S. A., Mirea, M., and Stoica, S.
Subjects: Nuclear Theory
Abstract: We show that the current search for Lorentz invariance violation (LIV) in the summed energy spectra of electrons in $2\nu\beta\beta$ decay can be extended by investigating the single electron spectra and the angular correlation between the emitted electrons. We derive and calculate the LIV contributions to these spectra associated with the anisotropic part of the countershaded operator and controlled through the coefficient $\mathring{a}_{\text{of}}^{(3)}$ and discuss possible signatures that may be probed in experiments. First, we show that some distortion occurs in the single electron spectrum, maximal at small electron energies. Then, we show that other LIV effects may be highlighted by analysing the angular correlation spectra and the ratio between the Standard Model Extension (SME) electron spectra and their Standard Model (SM) forms. We found that these LIV signatures depend on the magnitude of $\mathring{a}_{\text{of}}^{(3)}$, manifest differently for positive and negative values of this coefficient, and become more pronounced as the electron energy approaches the $Q$-value. Finally, we propose an alternative, new method to constrain $\mathring{a}_{\text{of}}^{(3)}$ through the measurement of the angular correlation coefficient. Using this method, and considering only statistical uncertainties, we obtain bounds of $\mathring{a}_{\text{of}}^{(3)}$ at the level of present ones, obtained from summed energy spectra. We show that future experiments can improve these limits significantly. Our study is performed for $^{100}$Mo, but the results hold qualitatively for other nuclei that undergo a double-beta decay. We hope our results will provide additional motivation for the LIV analyses performed in DBD experiments., Comment: 7 pages, 4 figures

16. L-Shell capture dominance in 127Xe, 207Bi and 236Np.

Author: Sevestrean, V. A., Niţescu, O., Ghinescu, S., and Stoica, S.
Subjects: ELECTRON capture, ATOMIC mass, BINDING energy, WAVE functions, NEUTRINOS, ELECTRON configuration
Abstract: We present a study on low-energy electron capture ratios for three distinct nuclei (127Xe, 207Bi, 236Np). This investigation utilizes a self-consistent computational approach, which encompasses considerations such as electron screening, electron correlations, overlap, exchange corrections, and shake-up and shake-off atomic effects. The electronic wave functions are computed using the Dirac-Hartree-Fock-Slater method. A noteworthy aspect of our calculations involves an energy balance approach that relies on atomic masses. This approach avoids the need for approximating the electron's total binding energy and, as a result, permits a more precise determination of the neutrino energy. In this study, we provide in-depth results for the above nuclei, highlighting peculiar behavior in the dominant shell from which the electron is captured during the decay process.

Abstract: The NA62 experiment reports the branching ratio measurement $BR(K^+\to\pi^+\nu\bar\nu)$ at 68% CL, based on the observation of 20 signal candidates with an expected background of 7.0 events from the total data sample collected at the CERN SPS during 2016-2018. This provides evidence for the very rare $K^+\to\pi^+\nu\bar\nu$ decay, observed with a significance of $3.4\sigma$. The experiment achieves a single event sensitivity of $(0.839\pm0.054)\times10^{-11}$, corresponding to 10.0 events assuming the Standard Model branching ratio of $(8.4\pm1.0)\times10^{-11}$. The result represents the most accurate measurement achieved so far of this ultra-rare decay. Future prospects and plans for data taking from 2021 will also be presented.

Abstract: Searches for heavy neutral lepton production in $K^{+} \to e^{+}N$ and $K^{+} \to \mu ^{+}N$ decays using the data set collected by the NA62 experiment at CERN in 2016-18 are presented. Upper limits on the elements of the extended neutrino mixing matrix and are established at the levels of and , respectively, improving on the earlier searches for heavy neutral lepton production and decays in the kinematically accessible mass range. Searches for the $K^{+} \to \mu ^{+}\nu \nu \bar{\nu }$ and $K^{+} \to \mu ^{-}\nu X$ decays, where $X$ is an new light invisible particle, are also reported.

Abstract: The NA62 experiment at CERN collected a large sample of charged kaon decays into ﬁnal states with multiple charged particles in 2016-2018. This sample provides sensitivities to rare decays with branching ratios as low as 10 −11 . Searches for the lepton number violating $K^{+} \to \pi ^{-}\mu ^{+}e^{+}$ decay and the lepton ﬂavour violating $K^{+} \to \pi ^{+}\mu ^{-}e^{+}$ and $\pi ^{0} \to \mu ^{-}e^{+}$ decays are reported. No evidence for these decays is found and upper limits of the branching ratios are obtained at 90% conﬁdence level. These results improve by one order of magnitude over previous results for these decay modes.

Abstract: The NA62 experiment at CERN reports searches for $K^+ \to e^+ N$, $K^+ \to \mu^+ N$ and $K^+ \to \mu^+ X$ decays, where $N$ and $X$ are massive invisible particles, using the 2016-2018 data set. The $N$ particle is assumed to be a heavy neutral lepton, and the results are expressed as upper limits of $O(10^{-9})$ and $O(10^{-8})$ on the neutrino mixing parameter $|U_{e4}|^2$ and $|U_{\mu 4}|^2$, improving on the earlier searches for heavy neutral lepton production and decays in the kinematically accessible mass range. The $X$ particle is considered a scalar or vector hidden sector mediator decaying to an invisible final state, and upper limits of the decay branching fraction for $X$ masses in the range 10-370 MeV/c$^2$ are reported for the first time, ranging from $O(10^{-5})$ to $O(10^{-7})$. An upper limit of $1.0 \cdot 10^{-6}$ is established at 90\% CL on the $K^+\to \mu^+ \nu \nu \bar{\nu}$ branching fraction.

Abstract: We report the results of a search for dark photon in-flight decays to μ + μ − pairs at NA62. Dark photons could be produced by dumping protons onto a copper-iron absorber, reach the NA62 decay volume more than 80 m downstream of the dump and decay therein. The measurement is based on data collected in 2021 which correspond to 1.4 × 1017 dumped protons.

Abstract: In this paper we present new results on upper limits for the search of Heavy Neutral Leptons (HNL) with data collected by NA48/2 (2003-2004), NA62-RK (2007) and NA62 (2015) CERN experiments. The data collected with different trigger configuration allow to search for both long and short living heavy neutrinos in the mass range below the kaon mass. In addition the status of the search for K+ → π+vv with the NA62 detector will be briefly presented.

Abstract: The NA62 experiment reports an investigation of the K+→ π+νν¯ mode from a sample of K+ decays collected in 2017 at the CERN SPS. The experiment has achieved a single event sensitivity of (0.389 ± 0.024) × 10−10, corresponding to 2.2 events assuming the Standard Model branching ratio of (8.4 ± 1.0) × 10−11. Two signal candidates are observed with an expected background of 1.5 events. Combined with the result of a similar analysis conducted by NA62 on a smaller data set recorded in 2016, the collaboration now reports an upper limit of 1.78 × 10−10 for the K+→ π+νν¯ branching ratio at 90% CL. This, together with the corresponding 68% CL measurement of (0.48−0.48+0.72) × 10−10, are currently the most precise results worldwide, and are able to constrain some New Physics models that predict large enhancements still allowed by previous measurements.

Abstract: A review of selected recent results from experiments studying rare kaon decays in Europe is given. The results from the NA62 experiment at CERN are summarized in the first part of this report. The experiment produced a new preliminary upper limit on the $K^{ + } \to \pi ^{ + }\nu \bar{\nu }$ branching ratio of 1.85 × 10^−10 at 90% CL, based on the data recorded in 2016 and 2017. NA62 also performed searches for production of heavy neutral leptons (N) in $K^{ + } \to \ell ^{ + }N$ ($\ell = e,\mu $), and for lepton number violating processes $K^{ + } \to \pi ^{ - }\ell ^{ + }\ell ^{ + }$ ($\ell = e,\mu $). No significant signal was observed in these searches, and the world-leading upper limits have been set. In the second part of this review, we summarize the first observation and the branching ratio measurement of the $K^{ \pm } \to \pi ^{ \pm }\pi ^{0}e^{ + }e^{ - }$ decay by the NA48/2 experiment, a new preliminary measurement of the $K_{S} \to \pi ^{ \pm }\mu ^{ \mp }\nu $ branching ratio by the KLOE experiment, and a new upper limit on the $K_{S} \to \mu ^{ + }\mu ^{ - }$ branching ratio by the LHCb experiment.
