Abstract

This Report summarizes the results of the activities of the LHC Higgs Cross Section Working Group in the period 2014-2016. The main goal of the working group was to present the state-of-the-art of Higgs physics at the LHC, integrating all new results that have appeared in the last few years. The first part compiles the most up-to-date predictions of Higgs boson production cross sections and decay branching ratios, parton distribution functions, and off-shell Higgs boson production and interference effects. The second part discusses the recent progress in Higgs effective field theory predictions, followed by the third part on pseudo-observables, simplified template cross section and fiducial cross section measurements, which give the baseline framework for Higgs boson property measurements. The fourth part deals with the beyond the Standard Model predictions of various benchmark scenarios of Minimal Supersymmetric Standard Model, extended scalar sector, Next-to-Minimal Supersymmetric Standard Model and exotic Higgs boson decays. This report follows three previous working-group reports: Handbook of LHC Higgs Cross Sections: 1. Inclusive Observables (CERN-2011-002), Handbook of LHC Higgs Cross Sections: 2. Differential Distributions (CERN-2012-002), and Handbook of LHC Higgs Cross Sections: 3. Higgs properties (CERN-2013-004). The current report serves as the baseline reference for Higgs physics in LHC Run 2 and beyond., Comment: 869 pages, 295 figures, 248 tables and 1645 citations.

Abstract

This report summarizes the work of the Energy Frontier Higgs Boson working group of the 2013 Community Summer Study (Snowmass). We identify the key elements of a precision Higgs physics program and document the physics potential of future experimental facilities as elucidated during the Snowmass study. We study Higgs couplings to gauge boson and fermion pairs, double Higgs production for the Higgs self-coupling, its quantum numbers and $CP$-mixing in Higgs couplings, the Higgs mass and total width, and prospects for direct searches for additional Higgs bosons in extensions of the Standard Model. Our report includes projections of measurement capabilities from detailed studies of the Compact Linear Collider (CLIC), a Gamma-Gamma Collider, the International Linear Collider (ILC), the Large Hadron Collider High-Luminosity Upgrade (HL-LHC), Very Large Hadron Colliders up to 100 TeV (VLHC), a Muon Collider, and a Triple-Large Electron Positron Collider (TLEP).

This Report summarizes the results of the activities in 2012 and the first half of 2013 of the LHC Higgs Cross Section Working Group. The main goal of the working group was to present the state of the art of Higgs Physics at the LHC, integrating all new results that have appeared in the last few years. This report follows the first working group report Handbook of LHC Higgs Cross Sections: 1. Inclusive Observables (CERN-2011-002) and the second working group report Handbook of LHC Higgs Cross Sections: 2. Differential Distributions (CERN-2012-002). After the discovery of a Higgs boson at the LHC in mid-2012 this report focuses on refined prediction of Standard Model (SM) Higgs phenomenology around the experimentally observed value of 125-126 GeV, refined predictions for heavy SM-like Higgs bosons as well as predictions in the Minimal Supersymmetric Standard Model and first steps to go beyond these models. The other main focus is on the extraction of the characteristics and properties of the newly discovered particle such as couplings to SM particles, spin and CP-quantum numbers etc., Comment: 404 pages, 139 figures, 162 tables.

Subjects
High Energy Physics - Phenomenology
Abstract

We extend the generalized D-dimensional unitarity method for numerical evaluation of one-loop amplitudes by incorporating massive particles. The issues related to extending the spinor algebra to higher dimensions, treatment of external self-energy diagrams and mass renormalization are discussed within the context of the D-dimensional unitarity method. To validate our approach, we calculate in QCD the one-loop scattering amplitudes of a massive quark pair with up to three additional gluons for arbitrary spin states of the external quarks and gluons., Comment: 18 pages, 2 figures

7. Relating bottom quark mass in DR-bar and MS-bar regularization schemes

Subjects
High Energy Physics - Phenomenology
Abstract

The value of the bottom quark mass at M_Z in the DR-bar scheme is an important input for the analysis of supersymmetric models with a large value of tan(beta). Conventionally, however, the running bottom quark mass extracted from experimental data is quoted in the MS-bar scheme at the bottom mass scale. We describe a two loop procedure for the conversion of the bottom quark mass from MS-bar to DR-bar scheme. The Particle Data Group value m_b(m_b) = 4.2 \pm 0.2 GeV in the MS-bar scheme corresponds to a range of 2.65-3.03 GeV for m_b(M_Z) in the DR-bar scheme., Comment: RevTex4, 5 pages, 1 figure

Abstract

Using non-relativistic effective theories, new next-to-next-to-leading order (NNLO) QCD corrections to the total $t\bar t$ production cross section at the Linear Collider have been calculated recently. In this article the NNLO calculations of several groups are compared and the remaining uncertainties are discussed. The theoretical prospects for an accurate determination of top quark mass parameters are discussed in detail. An outlook on possible future improvements is given., Comment: 21 pages, latex, 8 postscript figures included, contribution to the Proceedings of the 2nd joint ECFA/DESY Workshop on Physics Studies for a Future Linear Collider

Abstract

The potential of DAPHNE to explore direct radiative decay $\phi \to \pi^+ \pi^- \gamma$ is studied in detail. Predictions of different theoretical models for this decay are compared. We find that it should be possible to discriminate between these models at DAPHNE in one year, even assuming a relatively low luminosity ${\cal{L}} = 10^{31} {\rm cm}^{-2} {\rm sec^{-1}}$. The influence of the decay $\phi \to \pi^+ \pi^- \gamma$ on the measurement of total cross section $\sigma(e^+e^- \to {\rm hadrons})$ by tagging a photon in the reaction $e^+e^- \to \pi^+\pi^- \gamma$ is also discussed., Comment: 16 pages, 5 figures

High Energy Physics - Phenomenology
Abstract

We present an analytic calculation of the m*alpha^6 recoil corrections to the hyperfine splitting (HFS) of the ground state energy levels in positronium. We find \Delta E_{\rm rec} = m alpha^6 (-1/6 ln(alpha) + 331/432 -ln(2)/4 - 17 Zeta(3)/(8 pi^2) + 5/(12 pi^2)) \approx m alpha^6 (- 1/6 ln(alpha) + 0.37632), confirming Pachucki's numerical result \cite{Ph}. We present a complete analytic formula for the m*alpha^6 HFS of the positronium ground state and, including m*alpha^7*ln^2(alpha) effects, find E(1^3S_1)-E(1^1S_0))_{theory} = 203 392(1) MHz. This differs from the experimental results by about 3 standard deviations., Comment: 8 pages, RevTex

High Energy Physics - Phenomenology
Abstract

We present qualitative but precise description of the linear beam-size effect predicted for the processes in which unstable but long--living particles collide with each other. We derive physically pronounced equation for the events rate which proves that the linear beam-size effect corresponds to the scattering of one beam of particles on the decay products of the other. We compare this linear beam-size effect with the known logarithmic beam-size effect measured in the experiments on a single bremsstrahlung at VEPP-4 and HERA., Comment: 12 pages, LaTeX, 1 figure

13. Processes with the $t$-channel singularity in the physical region: finite beam sizes make cross sections finite

Author

Melnikov, K. and Serbo, V. G.

Subjects
High Energy Physics - Phenomenology
Abstract

It is known that some high-energy processes have a $t$-channel singularity in the physical region. In this paper we show that this singularity is regularized if one takes into account the finite sizes of the colliding beams, i.e. the realistic situation which takes place at high--energy colliders. On this way we obtain the finite cross section which is linear proportional to the transverse sizes of the colliding beams. As an application of the above result we study the production of the single $W$ boson at $\mu^+\mu^-$ colliders in the reaction $\mu ^- \mu ^+ \to e \bar \nu _e W^+ $. For the total energy $\sqrt {s}\approx 95$ GeV and reasonable parameters of the muon beams the ``beam--size '' dependent part of the cross section for this reaction is of the order of the standard cross section of the $\mu ^- \mu ^+ \to \mu^- \bar \nu _{\mu} W^+ $ process., Comment: Latex, 17 pages, 3 figures

14. New type of beam size effect and the $W$-boson production at $\mu^+\mu^-$ colliders

Subjects
High Energy Physics - Phenomenology
Abstract

The cross section for the reactions of the type $\mu^-\mu^+ \to e\bar\nu_e X$ can not be calculated by the standard methods due to the $t$--channel singularity in the physical region. In this letter we show that accounting for the finite sizes of the colliding beams results in the regularization of this singularity. The finite cross section, which is obtained in this way, turns out to be linear proportional to the transverse sizes of the colliding beams. As an application of the above result, we calculate the cross section of the $W$ boson production at $\mu^+\mu^-$ colliders in the reaction $\mu^- \mu^+ \to e\bar\nu _e W^+$., Comment: Latex, 8 pages, 2 figures

15. Two-loop $O(N_f\alpha _s^2)$ correction to the decay width of the Higgs boson to two massive fermions

Abstract

We present an analytical calculation of additional real or virtual radiation of the light fermion pair in the fermionic decay of the Higgs boson $ H \to f_1\bar f_1$ for arbitrary ratios of the Higgs boson mass to the $f_1$ fermion mass. This result gives us a value of the $O(N_f \alpha _s^2)$ radiative correction to the inclusive decay rate $ H \to f_1\bar f_1$. Using this result in the framework of the Brodsky-Mackenzie-Lepage scheme, we discuss the scale setting in the one-loop QCD correction to the decay width $ H \to f_1\bar f_1$ for arbitrary relation between the Higgs boson and fermion masses., Comment: Latex, 18 pages, 4 uuencoded figures, some misprints in formulas are corrected

Abstract

This note is devoted to the calculation of the two-loop $O(G_F {M_H}^2)$ radiative corrections to the Higgs decay width $H \to \gamma \gamma $ for large values of the Higgs boson mass $M_H$ within the Minimal Standard Model. The use of the Equivalence Theorem makes it possible to reduce the problem to the consideration of the physical Higgs boson field and the Goldstone bosons $w^{+},w^{-},z$. We present analytical results for the various two- and three-particle absorptive parts of two-loop contributions, using dispersive techniques, analytic results for all but one of the dispersive contributions. The typical size of the correction is $\sim ~30 $ percent for a Higgs boson mass of order $1~TeV$., Comment: 21 pages, 7 uuencoded figures

Abstract

It is shown that the methods which have been used up to now to determine the $W$ width from the $p\bar p$ data confirm the SM predictions for some combinations of various phenomenological parameters, however, they do not give an independent value for the $W$ width. Moreover, the accuracy that could be achieved in future experimental checks of SM predictions for such quantities is limited by effects which require detailed theoretical study., Comment: Latex, 8 pages.

Abstract

We consider the small velocity sum rules for heavy flavour semileptonic transitions that are used to estimate the zero recoil values of semileptonic heavy flavour form factors. We analyze the complete O($\alpha _S$) radiative correction to these sum rules. The corrections are universal and influence all "model-independent" bounds previously derived for semileptonic form factors at zero recoil., Comment: 13 pages, LaTeX, 3 figures

19. Final state interaction in the production of heavy unstable particles

Author

Subjects
High Energy Physics - Phenomenology
Abstract

We make an attempt to discuss in detail the effects originating from the final state interaction in the processes involving production of unstable elementary particles and their subsequent decay. Two complementary scenarios are considered: the single resonance production and the production of two resonances. We argue that part of the corrections due to the final state interaction can be connected with the Coulomb phases of the involved charge particles; the presence of the unstable particle in the problem makes the Coulomb phase ``visible''. It is shown how corrections due to the final state interaction disappear when one proceeds to the total cross-sections. We derive one-loop non-factorizable radiative corrections to the lowest order matrix element of both single and double resonance production. We discuss how the infrared limit of the theories with the unstable particles is modified. In conclusion we briefly discuss our results in the context of the forthcoming experiments on the $W^+W^-$ and the $t\bar t$ production at LEP $2$ and NLC., Comment: 33 pages, latex, 6 figures (added), version accepted for publication in Nuc.

Abstract

In this note we report some model-independent bounds involving transition form factors for $ \Omb \rightarrow \Omc $ and $ \Omb \rightarrow \Omc ^* $ and the nonperturbative matrix elements of the $ \Omb $ system.

21. Top Near Threshold: All QCD Radiative Corrections are Trivial

Abstract

We have calculated part of O(${\alpha}_{S}$) QCD radiative correction to the total cross-section of top's threshold production in $ e^{+}e^{-} \to t\bar t \to W^{-} b W^{+} \bar b$ reaction. We found out a curious fact: there is no O(${\alpha}_{S}$) correction to the total cross-section, originated from $b \bar b , t \bar b ,\bar t b $ gluon exchange and corresponding gluon emission. Thus, all O(${\alpha}_{S}$) corrections which are non-zero, can be classified as: 1) corrections to $t \bar t$ nonrelativistic potential 2) corrections to the top's width 3) hard gluon correction to $\gamma t \bar t$-vertex. These corrections are well-known and were described in the previous papers. We can conclude that similar situation takes place for all unstable particles threshold production. This result can be expressed in the form of a general statment: There is no O(${\alpha}_{QED}$ or ${\alpha}_{QCD}$) corrections for the total cross-section , originated from the "jet-jet" interection., Comment: 7 pages , figures described but not included, available on request

22. Higgs - Two Photon Decay: QCD radiative correction

Author

Subjects

Abstract

QCD radiative correction to Higgs $\rightarrow$ two photons decay rate is calculated. Below the threshold we found negligible correction, thus supporting results obtained earlier by Djouadi et all [7]. Above the threshold radiative correction appears to be large for both real and imaginary part of H $\gamma \gamma$ vertex. This leads to radiative correction for $\Gamma $(H $\rightarrow \gamma \gamma $) to be of order 20--100 percents at $m_{t}=150 GeV$. Possible applications of our results for Higgs search at Next Linear Colliders (NLC) are briefly discussed., Comment: 6 pagers, 5 figuresdescribed but not included, available on request.

26. Noncancellation of infrared singularities in collisions of massive quarks

Abstract

We discuss the infrared structure of processes with massive quarks in the initial state. It is well known that, starting from next-to-next-to-leading order in perturbative QCD, such processes exhibit a violation of the Bloch-Nordsieck theorem, in that the sum of real and virtual contributions to partonic cross sections contains uncanceled infrared singularities. The main purpose of this paper is to present a simple physical argument that elucidates the origin of these singularities and simplifies the derivation of infrared-singular contributions to heavy-quark initiated cross sections.

Abstract

I discuss how perturbative QCD can be used to describe outcomes of hard hadron collisions in a detailed and precise way. To an extent that four lectures permit, we touch upon fixed order computations, resummations, parton distribution functions and parton showers. Main ideas behind these concepts are explained and derivations of many important results are given. The importance of understanding the soft and collinear limits of scattering amplitudes for the perturbative QCD description of hadron collisions is repeatedly emphasized., CERN Yellow Reports: School Proceedings, Vol 3 (2018): Proceedings of the 2017 European School of High-Energy Physics

Abstract

This Report summarizes the results of the activities in 2012 and the first half of 2013 of the LHC Higgs Cross Section Working Group. The main goal of the working group was to present the state of the art of Higgs Physics at the LHC, integrating all new results that have appeared in the last few years. This report follows the first working group report Handbook of LHC Higgs Cross Sections: 1. Inclusive Observables (CERN-2011-002) and the second working group report Handbook of LHC Higgs Cross Sections: 2. Differential Distributions (CERN-2012-002). After the discovery of a Higgs boson at the LHC in mid-2012 this report focuses on refined prediction of Standard Model (SM) Higgs phenomenology around the experimentally observed value of 125-126 GeV, refined predictions for heavy SM-like Higgs bosons as well as predictions in the Minimal Supersymmetric Standard Model and first steps to go beyond these models. The other main focus is on the extraction of the characteristics and properties of the newly discovered particle such as couplings to SM particles, spin and CP-quantum numbers etc.

Abstract

The production of a Standard Model Higgs boson in association with two hard jets in the forward and backward regions of the detector, frequently quoted as the “vector-boson fusion” (VBF) channel, and the production of a Higgs boson in association with a W or Z boson, known as “VH production” or “Higgsstrahlung”, represent cornerstones in a comprehensive study of Higgs boson couplings at the LHC. These production channels do not only provide valuable information on the couplings of Higgs bosons to the massive gauge bosons by themselves, but also allow for the isolation of the Higgs boson decays into -lepton or bottom-quark pairs, whose investigation is essential in the Higgs boson couplings analysis. In the previous reports [7–9], state-of-the-art predictions and error estimates for the total and differential cross sections for pp ! H + 2 jets and pp ! HV ! H + 2 leptons were compiled (with V = W; Z), but the process of improving and refining predictions is still ongoing, even within the Standard Model. In this contribution we update the cross-section predictions for VBF and VH production, covering integrated total and fiducial cross sections as well as differential distributions. In detail, the presented state-of-the-art predictions include QCD corrections up to next-to-next-to-leading order (NNLO), electroweak (EW) corrections up to next-to-leading order (NLO), and contributions from specific partonic channels that open at higher perturbative orders, such as photon-induced collisions or gluon-fusion contributions. Apart from collecting numerical results, we give recommendations as to how to combine the individual components and to assess conservative estimates of remaining theoretical uncertainties. Moreover, issues connected to the matching and the impact of parton showers (PS) are discussed.

Abstract

We compute the leading color, next-to-leading order QCD corrections to the dominant partonic channels for the production of a W boson in association with three jets at the Tevatron and the LHC. This is the first application of generalized unitarity for realistic one-loop calculations. The method performs well in this non-trivial test and offers great promise for the future. © SISSA 2009.

Abstract

This Report summarizes the results of the activities of the LHC Higgs Cross Section Working Group in the period 2014-2016. The main goal of the working group was to present the state-of-the-art of Higgs physics at the LHC, integrating all new results that have appeared in the last few years. The first part compiles the most up-to-date predictions of Higgs boson production cross sections and decay branching ratios, parton distribution functions, and off-shell Higgs boson production and interference effects. The second part discusses the recent progress in Higgs effective field theory predictions, followed by the third part on pseudo-observables, simplified template cross section and fiducial cross section measurements, which give the baseline framework for Higgs boson property measurements. The fourth part deals with the beyond the Standard Model predictions of various benchmark scenarios of Minimal Supersymmetric Standard Model, extended scalar sector, Next-to-Minimal Supersymmetric Standard Model and exotic Higgs boson decays. This report follows three previous working-group reports: Handbook of LHC Higgs Cross Sections: 1. Inclusive Observables (CERN-2011-002), Handbook of LHC Higgs Cross Sections: 2. Differential Distributions (CERN-2012-002), and Handbook of LHC Higgs Cross Sections: 3. Higgs properties (CERN-2013-004). The current report serves as the baseline reference for Higgs physics in LHC Run 2 and beyond., Comment: 869 pages, 295 figures, 248 tables and 1645 citations.
