Higgs pair production through gluon fusion is an important process at the LHC to test the dynamics underlying electroweak symmetry breaking. Higgs sectors beyond the Standard Model (SM) can substantially modify this cross section through novel couplings not present in the SM or the on-shell production of new heavy Higgs bosons that subsequently decay into Higgs pairs. CP violation in the Higgs sector is important for the explanation of the observed matter-antimatter asymmetry through electroweak baryogenesis. In this work we compute the next-to-leading order (NLO) QCD corrections in the heavy top quark limit, including the effects of CP violation in the Higgs sector. We choose the effective theory (EFT) approach, which provides a rather model-independent way to explore New Physics (NP) effects by adding dimension-6 operators, both CP-conserving and CP-violating ones, to the SM Lagrangian. Furthermore, we perform the computation within a specific UV-complete model and choose as benchmark model the general 2-Higgs-Doublet Model with CP violation, the C2HDM. Depending on the dimension-6 coefficients, the relative NLO QCD corrections are affected by several per cent through the new CP-violating operators. This is also the case for SM-like Higgs pair production in the C2HDM, while the relative QCD corrections in the production of heavier C2HDM Higgs boson pairs deviate more strongly from the SM case. The absolute cross sections both in the EFT and the C2HDM can be modified by more than an order of magnitude. In particular, in the C2HDM the resonant production of Higgs pairs can by far exceed the SM cross section.

Interference and mixing effects between neutral Higgs bosons in the MSSM with complex parameters are shown to have a significant impact on the interpretation of LHC searches for additional Higgs bosons. Complex MSSM parameters introduce mixing between the CP-even and CP-odd Higgs states and generate CP-violating interference terms. Both effects are enhanced in the case of almost degenerate states. Employing as an example an extension of a frequently used benchmark scenario by a non-zero phase φ{sub A{sub t}}, the interference contributions are obtained for the production of neutral Higgs bosons in gluon-fusion and in association with b-quarks followed by the decay into a pair of τ-leptons. While the resonant mixing increases the individual cross sections for the two heavy Higgs bosons h{sub 2} and h{sub 3}, strongly destructive interference effects between the contributions involving h{sub 2} and h{sub 3} leave a considerable parameter region unexcluded that would appear to be ruled out if the interference effects were neglected.

We introduce and explore new heavy Higgs scenarios in the Minimal Supersymmetric Standard Model (MSSM) with explicit CP violation, which have important phenomenological implications that may be testable at the LHC. For soft supersymmetry-breaking scales M_S above a few TeV and a charged Higgs boson mass M_H+ above a few hundred GeV, new physics effects including those from explicit CP violation decouple from the light Higgs boson sector. However, such effects can significantly alter the phenomenology of the heavy Higgs bosons while still being consistent with constraints from low-energy observables, for instance electric dipole moments. To consider scenarios with a charged Higgs boson much heavier than the Standard Model (SM) particles but much lighter than the supersymmetric particles, we revisit previous calculations of the MSSM Higgs sector. We compute the Higgs boson masses in the presence of CP violating phases, implementing improved matching and renormalization group (RG) effects, as well as two-loop RG...

Higgs pair production in the CP-violating two-Higgs-doublet model

Science.gov (United States)

Bian, Ligong; Chen, Ning; Jiang, Yun

2017-12-01

The SM-like Higgs pair production is discussed in the framework of the general CP-violating two-Higgs-doublet model, where we find that the CP-violating mixing angles can be related to the Higgs self-couplings. Therefore, the future experimental searches for Higgs boson pairs can be constrained by the improved precision of the electric dipole moment measurements. Based on a series of constraints of the SM-like Higgs boson signal fits, the perturbative unitarity and stability bounds to the Higgs potential, and the most recent LHC searches for heavy Higgs bosons, we suggest a set of benchmark models for the future high-energy collider searches for Higgs pair production. The e+e- colliders operating at s = (500GeV,1 TeV) are capable of measuring the Higgs cubic self-couplings of the benchmark models directly. We also estimate the cross sections of the resonance contributions to the Higgs pair productions for the benchmark models at the future LHC and SppC/FCC-hh runs.

SM with two Higgs doublets: an example of CP-violation without Fermions

International Nuclear Information System (INIS)

Cvetic, G.

1993-01-01

Some CP-violation effects without fermions in the Standard Model are investigated with two Higgs doublets. First, the mass eigenstates of the physical neutral Higgses are calculated for small but nonzero CP-violation parameter ξ * , and then a ''forward-backward'' asymmetry A fb for the decay H → W + W - Z that would be a signal of CP-violation. The effects are in general small. However, A fb turns out to be a rather clean signal of CP-violation: neither the CP-conserving final state interactions nor the direct production background events contribute to Γ fb . The KM-type CP-violation effects that could in principle also contribute to A fb are negligible. 6 refs

Effects of Higgs sector CP violation in top-quark pair production at the LHC

CERN Document Server

Bernreuther, W; Flesch, M

1998-01-01

A striking manifestation of CP violation in the electroweak symmetry breaking sector would be the existence of neutral Higgs boson(s) with undefined CP parity. We analyse signatures of such a boson, with a mass of about 300 GeV or larger, produced in high energy proton-proton collisions at LHC energies in its top-quark antitop-quark decay channel. The large irreducible $t\\bar t$ background is taken into account. We propose, both for the dilepton and the lepton + jets decay channels of $t\\bar t$, several correlations and asymmetries with which (Higgs sector) CP violation can be traced. We show that for judiciously chosen cuts on the $t\\bar t$ invariant mass these CP observables yield, for an LHC integrated luminosity of 100 $\\rm{fb}^{-1}$, statistically significant signals for a range of Higgs boson masses and Yukawa couplings.

In a general two-Higgs-doublet model with CP violation in the Higgs sector, the three neutral physical Higgs bosons have no definite CP properties. A new sum rule relating Yukawa and Higgs-Z couplings implies that a neutral Higgs boson cannot escape detection at an e^+e^- collider if it is kinematically accessible in Z+Higgs, $b\\bar b+$Higgs and $t\\bar t+$Higgs production, irrespective of the mixing angles and the masses of the other neutral Higgs bosons.

We generalize the analysis to a Higgs sector consisting of an arbitrary number of Higgs doublets and singlets, giving explicit limits for the CP-conserving and CP-violating two-doublet plus one-singlet Higgs sectors. copyright 1997 The American Physical Society

Upper limits on the cross-section of the pair-production process e+e- -> h0A0 assuming 100% decays into hadrons, are derived from a new search for the h0A0 -> hadrons topology, independent of the hadronic flavour of the decay products. Searches for the neutral Higgs bosons h0 and A0, are used to obtain constraints on the Type II Two Higgs Doublet Model (2HDM(11)) with no CP violation in the Higgs sector and no additional non Standard Model particles besides the five Higgs bosons. The analysis combines LEP1 and LEP2 data collected with the OPAL detctor up to the highest available centre-of-mass energies. The searches are sensitive to the h0, A0 -> qq, gg,tau+tau- and h0 -> A0A0 decay modes of the Higgs bosons. The 2HDM(II) parameter space is explored in a detailed scan. Large regions of the 2HDM(II) parameter space are excluded at the 95% CL in the (mh, mA), (mh, tanb) and (mA, tanb) planes, using both direct neutral Higgs boson searches and indirect limits derived from Standard Model high precision measuremen...

Higgs pair production in the MSSM with explicit CP violation

International Nuclear Information System (INIS)

Demir, D.A.

1999-07-01

In the minimal supersymmetric standard model with explicit CP violation, associated production of the lightest Higgs boson with heavier ones is analyzed. Due to explicit CP violation, the Higgs bosons are no longer CP eigenstates so that both of the heavy Higgs bosons contribute to the process. While the radiative corrections in the Higgs sector turn out to be quite important, the vertex radiative corrections remain small as in the CP conserving theory. (author)

CP violation conditions in N-Higgs-doublet potentials

International Nuclear Information System (INIS)

Nishi, C. C.

2006-01-01

Conditions for CP violation in the scalar potential sector of general N-Higgs-doublet models are analyzed from a group theoretical perspective. For the simplest two-Higgs-doublet model potential, a minimum set of conditions for explicit and spontaneous CP violation is presented. The conditions can be given a clear geometrical interpretation in terms of quantities in the adjoint representation of the basis transformation group for the two doublets. Such conditions depend on CP-odd pseudoscalar invariants. When the potential is CP invariant, the explicit procedure to reach the real CP-basis and the explicit CP transformation can also be obtained. The procedure to find the real basis and the conditions for CP violation are then extended to general N-Higgs-doublet model potentials. The analysis becomes more involved and only a formal procedure to reach the real basis is found. Necessary conditions for CP invariance can still be formulated in terms of group invariants: the CP-odd generalized pseudoscalars. The problem can be completely solved for three Higgs-doublets

Superweak-like models of CP violation

International Nuclear Information System (INIS)

Lavoura, L.

1992-01-01

I put forward a two-Higgs-doublet model in which CP violation is mediated only by the neutral Higgs bosons, via the mechanism of scalar-pseudoscalar mixing. In this model there is no CP violation in the exchange of either W bosons or of charged Higgs bosons. The model is therefore an approximate realization of the superweak theory of CP violation. It has only two basic CP-violating quantities. I point out that other models of this kind, but with more than two Higgs doublets, may also be built

A CP violating mixing matrix compatible with neutral flavour conservation and spontaneous CP violation

A specific ansatz for the Yukawa couplings of a four-generation SU(2) L x U(I) model with two Higgs doublets is discussed which leads to neutral flavour conservation, spontaneous CP violation and to a genuinely complex mixing matrix. W exchange conserves CP in the limit m t' = m t only. The decay rate for t → b is reduced by a factor two compared to the Standard Model with three generations. The phenomenological implications for K 0 -K-bar 0 and B 0 -B-bar 0 are investigated. (Author)

Impact of a CP-violating Higgs sector: from LHC to baryogenesis.

Science.gov (United States)

Shu, Jing; Zhang, Yue

2013-08-30

We observe a generic connection between LHC Higgs data and electroweak baryogenesis: the particle that contributes to the CP-odd hgg or hγγ vertex would provide the CP-violating source during a first-order phase transition. It is illustrated in the two Higgs doublet model that a common complex phase controls the lightest Higgs properties at the LHC, electric dipole moments, and the CP-violating source for electroweak baryogenesis. We perform a general parametrization of Higgs effective couplings and a global fit to the LHC Higgs data. Current LHC measurements prefer a nonzero phase for tanβ≲1 and electric dipole moment constraints still allow an order-one phase for tanβ∼1, which gives sufficient room to generate the correct cosmic baryon asymmetry. We also give some prospects in the direct measurements of CP violation in the Higgs sector at the LHC.

Direct and indirect constraints on CP-violating Higgs-quark and Higgs-gluon interactions

International Nuclear Information System (INIS)

Chien, Y.T.; Cirigliano, V.; Dekens, W.; Vries, J. de; Mereghetti, E.

2016-01-01

We investigate direct and indirect constraints on the complete set of anomalous CP-violating Higgs couplings to quarks and gluons originating from dimension-6 operators, by studying their signatures at the LHC and in electric dipole moments (EDMs). We show that existing uncertainties in hadronic and nuclear matrix elements have a significant impact on the interpretation of EDM experiments, and we quantify the improvements needed to fully exploit the power of EDM searches. Currently, the best bounds on the anomalous CP-violating Higgs interactions come from a combination of EDM measurements and the data from LHC Run 1. We argue that Higgs production cross section and branching ratios measurements at the LHC Run 2 will not improve the constraints significantly. On the other hand, the bounds on the couplings scale roughly linearly with EDM limits, so that future theoretical and experimental EDM developments can have a major impact in pinning down interactions of the Higgs.

Trilinear Higgs couplings in the two Higgs doublet model with CP violation

International Nuclear Information System (INIS)

Osland, Per; Pandita, P. N.; Selbuz, Levent

2008-01-01

We carry out a detailed analysis of the general two Higgs doublet model with CP violation. We describe two different parametrizations of this model, and then study the Higgs boson masses and the trilinear Higgs couplings for these two parametrizations. Within a rather general model, we find that the trilinear Higgs couplings have a significant dependence on the details of the model, even when the lightest Higgs boson mass is taken to be a fixed parameter. We include radiative corrections in the one-loop effective potential approximation in our analysis of the Higgs boson masses and the Higgs trilinear couplings. The one-loop corrections to the trilinear couplings of the two Higgs doublet model also depend significantly on the details of the model, and can be rather large. We study quantitatively the trilinear Higgs couplings, and show that these couplings are typically several times larger than the corresponding standard model trilinear Higgs coupling in some regions of the parameter space. We also briefly discuss the decoupling limit of the two Higgs doublet model.

Models with extended two-doublet Higgs sector are discussed in view of using their particular features to find out which sources of CP violation could take place in nature. It is considered the effective two-Higgs-doublet potential with complex parameters, when the CP invariance is broken both explicitly and spontaneously. For case of the two-doublet Higgs sector of the minimal supersymmetric model, when CP invariance is violated by the interactions of Higgs fields with the third generation of scalar quarks, the Higgs bosons mass spectrum in the case of maximal CP mixing is calculated which is significantly different from CP-conserving case. The phenomenological consequences for the Higgs mass spectrum in the decoupling regime and for the strong mixing case are considered [ru

Neutral Naturalness from Orbifold Higgs Models

Craig, Nathaniel; Knapen, Simon; Longhi, Pietro

2015-02-01

We present a general class of natural theories in which the Higgs boson is a pseudo-Goldstone boson in an orbifolded gauge theory. The symmetry protecting the Higgs boson at low energies is an accidental global symmetry of the quadratic action, rather than a full continuous symmetry. The lightest degrees of freedom protecting the weak scale carry no standard model (SM) quantum numbers and interact with visible matter principally through the Higgs portal. This opens the door to the systematic study of "neutral naturalness": natural theories with SM-neutral states that are as yet untested by the LHC.

The authors evaluate weak mass mixing among the neutral heavy mesons with a bottom (Q=-1/3) or top (Q=+2/3) quark and CP violation in this framework of six quark V-A models. It is argued that bottom and top mesons may distinguish the Higgs exchange mechanism of CP violation from a complex phase in the quark mass matrix, if bottom and top quark masses are sufficiently different. Estimates of weak mixing and CP violating effects for e/sup +/e/sup -/ experiments at PETRA, PEP and CESR energies are presented.

To solve the μ problem of the Minimal Supersymmetric Standard Model (MSSM), a single field S is added to build the Next Minimal Supersymmetric Standard Model (NMSSM). Vacuum enlarged with non-zero vevs of the neutral-even CP is the combination of H u , H d and S. In the NMSSM, the higgs sector is increased to 7 higgs (compared with 5 higgs in the MSSM), including three higgs which are even-CP h 1,2,3 (m h1 < m h2 < m h3 ), two higgs which are odd-CP a 1,2 (m a1 < m a2 ) and a couple of charged higgs H ± . The decays higgs into higgs is one of the remarkable new points of the NMSSM. In this paper we study some decays of neutral Higgs bosons. The numerical results are also presented together with evaluations.

We propose a class of two Higgs doublet models where there are flavour changing neutral currents (FCNC) at tree level, but under control due to the introduction of a discrete symmetry in the full Lagrangian. It is shown that in this class of models, one can have simultaneously FCNC in the up and down sectors, in contrast to the situation encountered in the renormalisable and minimal flavour violating 2HDM models put forward by Branco et al. (Phys Lett B 380:119, 1996). The intensity of FCNC is analysed and it is shown that in this class of models one can respect all the strong constraints from experiment without unnatural fine-tuning. It is pointed out that the additional sources of flavour and CP violation are such that they can enhance significantly the generation of the Baryon asymmetry of the Universe, with respect to the standard model.

CP-violating supersymmetric Higgs boson at the Tevatron and LHC

International Nuclear Information System (INIS)

Das, Siba Prasad; Drees, Manuel

We analyze the prospect for observing the intermediate neutral Higgs boson (h 2 ) in its decay to two lighter Higgs bosons (h 1 ) at the presently operating hadron colliders in the framework of the CP-violating minimal supersymmetric standard model using the PYTHIA event generator. We consider the lepton+4-jets+E T channel from associate Wh 2 production, with Wh 2 >Wh 1 h 1 >lvlbb*-bb*-. We require two, three or four tagged b jets. We explicitly consider all relevant standard model backgrounds, treating c jets separately from light flavor and gluon jets and allowing for mistagging. We find that it is very hard to observe this signature at the Tevatron, even with 20 fb*-*1 of data, in the LEP-allowed region of parameter space due to the small signal efficiency, even though the background is manageable. At the LHC, a priori huge standard model backgrounds can be suppressed by applying judiciously chosen kinematical selections. After all cuts, we are left with a signal cross section of around 0.5 fb, and a signal to background ratio between 1.2 and 2.9. According to our analysis this Higgs signal should be viable at the LHC in the vicinity of present LEP exclusion once 20 to 50fb*-*1 of data have been accumulated at √(s)=14 TeV.

We consider the effective two-Higgs-doublet potential with complex parameters, when the CP invariance is broken both explicitly and spontaneously. The diagonal mass term in the local minimum of the potential is constructed for the physical basis of Higgs fields, keeping explicitly the limiting case of CP conservation, if the parameters are taken real. For the special case of the two-doublet Higgs sector of the minimal supersymmetric model, when CP invariance is violated by the Higgs bosons interaction with scalar quarks of the third generation, we calculate by means of the effective potential method the Higgs boson masses and evaluate the two-fermion Higgs boson decay widths and the widths of rare one-loop-mediated decays H→γγ, H→gg

Searches for neutral Higgs bosons produced at LEP in association with Z bosons, in pairs and in the Yukawa process are presented in this paper. Higgs boson decays into b quarks, τ leptons, or other Higgs bosons are considered, giving rise to four-b, four-b+jets, six-b and four-τ final states, as

Diffraction as a CP and lineshape analyzer for MSSM Higgs bosons at the CERN LHC

Ellis, John; Lee, Jae Sik; Pilaftsis, Apostolos

2005-01-01

We study the production and decay of a coupled system of mixed neutral minimal supersymmetric extension of the Standard Model (MSSM) Higgs bosons in exclusive double-diffractive processes at the LHC, including nonvanishing CP phases in the soft supersymmetry-breaking gaugino masses and third-generation trilinear squark couplings. The three neutral Higgs bosons are naturally nearly degenerate, for large values of tanβ, when the charged Higgs boson weighs around 150 GeV. Large mixing between all three neutral Higgs bosons is possible when CP is violated, a threeway mixing scenario which we also term trimixing. A resolution in the Higgs mass of ∼1 GeV, which may be achievable using the missing-mass method, would allow one to distinguish nearly degenerate Higgs bosons by studying the production lineshape. Measurements of the polarizations of the tau leptons coming from the Higgs-boson decays could offer a direct and observable signal of CP violation in the Higgs sector

Effects of the supersymmetric phases on the neutral Higgs sector

Demir, D.A.

1999-01-01

By using the effective potential approximation and taking into account the dominant top quark and scalar top quark loops, radiative corrections to MSSM Higgs potential are computed in the presence of the supersymmetric CP-violating phases. It is found that, the lightest Higgs scalar remains essentially CP-even as in the CP-invariant theory whereas the other two scalars are heavy and do not have definite CP properties. The supersymmetric CP-violating phases are shown to modify significantly the decay rates of the scalars to fermion pairs. (author)

Suppressing flavor-changing neutral currents and CP-violating phases by extra dimensions

International Nuclear Information System (INIS)

Kubo, Jisuke; Terao, Haruhiko

2002-01-01

In extra dimensions the infrared attractive force of gauge interactions is amplified. We find that this force can align in the infrared limit the soft-supersymmetry breaking terms out of their anarchical disorder at a fundamental scale in such a way that flavor-changing neutral currents as well as dangerous CP-violating phases are sufficiently suppressed at the unification scale. The main assumption is that the matter and Higgs supermultiplets and the flavor-dependent interactions such as Yukawa interactions are stuck at the four-dimensional boundary. As a concrete example we consider the minimal model based on SU(5) in six dimensions

Production of composite neutral Higgs bosons in photoproduction and e+e- experiments

International Nuclear Information System (INIS)

Whisnant, K.; Young, B.; Hu, S.

1985-01-01

We examine the consequences of a sizable tree-level coupling of a neutral Higgs boson to two photons, which could exist in composite models where the intermediate vector bosons and scalar Higgs bosons are made of the same subconstituents. We find that for certain ranges of the coupling strength and Higgs-boson mass, a neutral composite Higgs boson can be produced and detected in photon-proton scattering and e + e - annihilation at currently accessible energies. We also discuss other processes that are not present in the standard model at the tree level, but may lead to observable neutral-Higgs-boson production at, for instance, a p-barp collider

Electron Electric Dipole Moment from CP Violation in the Charged Higgs Sector

Bowser-Chao, D.; Keung, W.; Chang, D.; Chang, D.

1997-01-01

The leading contributions to the electron (or muon) electric dipole moment due to CP violation in the charged Higgs sector are at the two level. A careful model-independent analysis of the heavy fermion contribution is provided. We also consider some specific scenarios to demonstrate how charged Higgs sector CP violation can naturally give rise to large electric dipole moments. Numerical results show that the electron electric dipole moment in such models can lie at the experimentally accessible level. copyright 1997 The American Physical Society

Maxwell-Chern-Simons vortices in a CPT-odd Lorentz-violating Higgs electrodynamics

International Nuclear Information System (INIS)

Casana, R.; Ferreira, M.M.; Hora, E. da; Neves, A.B.F.

2014-01-01

We study BPS vortices in a CPT-odd and Lorentz-violating Maxwell-Chern-Simons-Higgs (MCSH) electrodynamics attained from the dimensional reduction of the Carroll-Field-Jackiw-Higgs model. The Lorentz-violating parameter induces a pronounced behavior at origin (for the magnetic/electric fields and energy density) which is absent in the MCSH vortices. For some combination of the Lorentz-violating coefficients there always exists a sufficiently large winding number n 0 such that for all vertical stroke n vertical stroke ≥ vertical stroke n 0 vertical stroke the magnetic field flips sign, yielding two well-defined regions with opposite magnetic flux. However, the total magnetic flux remains quantized and proportional to the winding number. (orig.)

Magnitude of Higgs-boson-exchange CP violation in two-doublet models with large tanβ

International Nuclear Information System (INIS)

Barr, S.M.

1993-01-01

CP violation in neutral Higgs-boson exchange is studied in two-doublet models in an expansion in (1/tan 2 β). The typical magnitude of various CP-violating quantities is found for large tanβ. In particular the electric dipole moment (EDM) of the electron and the coefficient c S of the CP-violating electron-nucleon scalar-pseudoscalar operator are examined and it is found that in a simple class of two-doublet models c S /d e is typically O(tan 2 β). Therefore c S is more important than d e for the EDM's of diamagnetic atoms and molecules (Hg, Xe, TlF) typically if tanβ approx-gt 5, and for paramagnetic atoms (Cs, Tl) if tanβ approx-gt 15. The dependence on tanβ of the various contributions to the neutron EDM including the Weinberg three-gluon operator, and the dependence on tanβ of the top-quark EDM are also discussed. Supersymmetric and three-doublet models are also considered

A Lorentz-Violating Alternative to Higgs Mechanism?

CERN Document Server

Alexandre, Jean

2011-01-01

We consider a four-dimensional field-theory model with two massless fermions, coupled to an Abelian vector field without flavour mixing, and to another Abelian vector field with flavour mixing. Both Abelian vectors have a Lorentz-violating kinetic term, introducing a Lorentz-violation mass scale $M$, from which fermions and the flavour-mixing vector get their dynamical masses, whereas the vector coupled without flavour mixing remains massless. When the two coupling constants have similar values in order of magnitude, a mass hierarchy pattern emerges, in which one fermion is very light compared to the other, whilst the vector mass is larger than the mass of the heavy fermion. The work presented here may be considered as a Lorentz-symmetry-Violating alternative to the Higgs mechanism, in the sense that no scalar particle (fundamental or composite) is necessary for the generation of the vector-meson mass. However, the model is not realistic given that, as a result of Lorentz Violation, the maximal (light-cone) s...

Lepton flavor violating Higgs couplings and single production of the Higgs boson via eγ collision

Yue, Chong-Xing; Pang, Cong; Guo, Yu-Chen

2015-01-01

Taking into account the constraints on the lepton flavor violation (LFV) couplings of the Standard Model (SM) Higgs boson H with leptons from low energy experiments and the recent Compact Muon Solenoid experiment results, we investigate production of the SM Higgs boson associated with a lepton τ via eγ collision at the International Linear Collider (ILC) and Large Hadron Electron Collider experiments. The production cross sections are calculated and the LFV signals and the relevant SM backgrounds are examined. The LFV signals of the SM Higgs boson might be observed via eγ collision in future ILC experiments. (paper)

Gluon fusion Higgs production in the CP violating MSSM

Energy Technology Data Exchange (ETDEWEB)

Patel, Shruti; Liebler, Stefan; Weiglein, Georg [DESY, Hamburg (Germany)

2016-07-01

The MSSM with complex parameters has emerged as an attractive SUSY candidate providing new sources of CP-violation, which are well motivated in the context of the observed imbalance between matter and antimatter in the universe. In order to study the effects of the complex parameters, which enter via loop contributions, an accurate prediction for the Higgs production cross-section is required. In this talk, we present a study of these effects carried out with an implementation in the program SusHi linked to FeynHiggs.

We discuss the implications of assuming a four–zero Yukawa ansatz for the neutral Higgs decays, within the context of the general 2–Higgs Doublet Model of type III. We begin by presenting a detailed analysis of the neutral Higgs boson couplings with fermions and gauge bosons and the resulting effects on its decays. In particular, we are interested on the possibility of the neutral Higgs boson production in current colliders

We study the phenomenological consequences of several CP-violating structures that could arise in the Standard Model effective field theory framework. Focusing on operators involving electroweak gauge and/or Higgs bosons, we derive constraints originating from Run I LHC data. We then study the capabilities of the present and future LHC runs at higher energies to further probe associated CP-violating phenomena and we demonstrate how differential information can play a key role. We consider both traditional four-lepton probes of CP-violation in the Higgs sector and novel new physics handles based on varied angular and non-angular observables. (orig.)

Cancellations Between Two-Loop Contributions to the Electron Electric Dipole Moment with a CP-Violating Higgs Sector.

Science.gov (United States)

Bian, Ligong; Liu, Tao; Shu, Jing

2015-07-10

We present a class of cancellation conditions for suppressing the total contributions of Barr-Zee diagrams to the electron electric dipole moment (eEDM). Such a cancellation is of particular significance after the new eEDM upper limit was released by the ACME Collaboration, which strongly constrains the allowed magnitude of CP violation in Higgs couplings and hence the feasibility of electroweak baryogenesis (EWBG). Explicitly, if both the CP-odd Higgs-photon-photon (Z boson) and the CP-odd Higgs-electron-positron couplings are turned on, a cancellation may occur either between the contributions of a CP-mixing Higgs boson, with the other Higgs bosons being decoupled, or between the contributions of CP-even and CP-odd Higgs bosons. With a cancellation, large CP violation in the Higgs sector is still allowed, yielding successful EWBG. The reopened parameter regions would be probed by future neutron, mercury EDM measurements, and direct measurements of Higgs CP properties at the Large Hadron Collider Run II and future colliders.

Particle currents in a space-time dependent and CP-violating Higgs background: a field theory approach

International Nuclear Information System (INIS)

Comelli, D.; Riotto, A.

1995-06-01

Motivated by cosmological applications like electroweak baryogenesis, we develop a field theoretic approach to the computation of particle currents on a space-time dependent and CP-violating Higgs background. We consider the Standard Model model with two Higgs doublets and CP violation in the scalar sector, and compute both fermionic and Higgs currents by means of an expansion in the background fields. We discuss the gauge dependence of the results and the renormalization of the current operators, showing that in the limit of local equilibrium, no extra renormalization conditions are needed in order to specify the system completely.

Semialigned two Higgs doublet model

Haba, Naoyuki; Umeeda, Hiroyuki; Yamada, Toshifumi

2018-02-01

In the left-right symmetric model based on S U (2 )L×S U (2 )R×U (1 )B -L gauge symmetry, there appear heavy neutral scalar particles mediating quark flavor changing neutral currents (FCNCs) at tree level. We consider a situation where such FCNCs give the only sign of the left-right model while WR gauge boson is decoupled, and name it "semialigned two Higgs doublet model" because the model resembles a two Higgs doublet model with mildly aligned Yukawa couplings to quarks. We predict a correlation among processes induced by quark FCNCs in the model, and argue that future precise calculation of meson-antimeson mixings and C P violation therein may hint at the semialigned two Higgs doublet model and the left-right model behind it.

Mass matrix ansatz and lepton flavor violation in the two-Higgs doublet model-III

2004-01-01

Predictive Higgs-boson-fermion couplings can be obtained when a specific texture for the fermion mass matrices is included in the general two-Higgs doublet model. We derive the form of these couplings in the charged lepton sector using a Hermitian mass matrix ansatz with four-texture zeros. The presence of unconstrained phases in the vertices φ i l i l j modifies the pattern of flavor-violating Higgs boson interactions. Bounds on the model parameters are obtained from present limits on rare lepton flavor-violating processes, which could be extended further by the search for the decay τ→μμμ and μ-e conversion at future experiments. The signal from Higgs boson decays φ i →τμ could be searched for at the CERN Large Hadron Collider, while e-μ transitions could produce a detectable signal at a future eμ collider, through the reaction e + μ - →h 0 →τ + τ -

HiggsBounds 2.0.0 is a computer code which tests both neutral and charged Higgs sectors of arbitrary models against the current exclusion bounds from the Higgs searches at LEP and the Tevatron. As input, it requires a selection of model predictions, such as Higgs masses, branching ratios, effective couplings and total decay widths. HiggsBounds 2.0.0 then uses the expected and observed topological cross section limits from the Higgs searches to determine whether a given parameter scenario of a model is excluded at the 95% C.L. by those searches. Version 2.0.0 represents a significant extension of the code since its first release (1.0.0). It includes now 28/53 LEP/Tevatron Higgs search analyses, compared to the 11/22 in the first release, of which many of the ones from the Tevatron are replaced by updates. As a major extension, the code allows now the predictions for (singly) charged Higgs bosons to be confronted with LEP and Tevatron searches. Furthermore, the newly included analyses contain LEP searches for neutral Higgs bosons (H) decaying invisibly or into (non flavour tagged) hadrons as well as decay-mode independent searches for neutral Higgs bosons, LEP searches via the production modes {tau}{sup +}{tau}{sup -}H and b anti bH, and Tevatron searches via t anti tH. Also, all Tevatron results presented at the ICHEP'10 are included in version 2.0.0. As physics applications of HiggsBounds 2.0.0 we study the allowed Higgs mass range for model scenarios with invisible Higgs decays and we obtain exclusion results for the scalar sector of the Randall-Sundrum model using up-to-date LEP and Tevatron direct search results.

A flavour independent search for the CP-even and CP-odd neutral Higgs bosons h and A is performed in 624/pb of data collected with the L3 detector at LEP at centre-of-mass energies between 189 and 209GeV. Higgs boson production through the e^+e^- -> Z h and the e^+e^- ->h A processes is considered and decays of the Higgs bosons into hadrons are studied. No significant signal is observed and 95% confidence level limits on the hZZ and hAZ couplings are derived as a function of the Higgs boson masses. Assuming the Standard Model cross section for the Higgs-strahlung process and a 100% branching fraction into hadrons, a 95% confidence level lower limit on the mass of the Higgs boson is set at 110.3GeV.

The Higgs Mass in the MSSM at two-loop order beyond minimal flavour violation

CERN Document Server

Goodsell, Mark D; Staub, Florian

2016-01-01

Soft supersymmetry-breaking terms provide a wealth of new potential sources of flavour violation, which lead to very tight constraints from precision experiments. This has posed a challenge to construct flavour models to both explain the structure of the Standard Model Yukawa couplings and how their consequent predictions for patterns in the soft supersymmetry-breaking terms do not violate these constraints. While such models have been studied in great detail, the impact of flavour violating soft terms on the Higgs mass at the two-loop level has been assumed to be small or negligible. In this letter, we show that large flavour violation in the up-squark sector can give a positive or negative shift to the SM-like Higgs of several GeV, without being in conflict with any other observation. We investigate in which regions of the parameter space these effects can be expected.

Searches for neutral Higgs bosons in the $\\tau \\tau$ final state with the CMS detector

Lane, Rebecca Charlotte

2015-01-01

The Compact Muon Solenoid (CMS) detector is located at the CERN Large Hadron Collider. It is a general purpose detector designed to test predictions of the standard model (SM) and search for the Higgs boson, as well as to look for signatures of new physics beyond the SM. The analyses described in this thesis use proton-proton collision data recorded by CMS during 2011 and 2012. Searches for neutral Higgs bosons decaying into tau pairs are presented. The searches are performed separately for the SM Higgs boson or the neutral Higgs bosons of the minimal supersymmetric standard model (MSSM). The MSSM searches consist of two different analyses. The first is a direct search for any one of the MSSM neutral Higgs bosons in the mass range from 90 GeV to 1 TeV decaying directly into taus. The second searches for the signature from a heavy neutral Higgs boson of the MSSM decaying into two light MSSM Higgs bosons with SM-like properties (H $\\to$ hh) in the final state with two b-quarks and two taus. The SM and MSSM $\\ta...

Electric dipole moments in two-Higgs-doublet models

Electric dipole moments are extremely sensitive probes for additional sources of CP violation in new physics models. Specifically, they have been argued in the past to exclude new CP-violating phases in two-Higgs-doublet models. Since recently models including such phases have been discussed widely, we revisit the available constraints in the presence of mechanisms which are typically invoked to evade flavour-changing neutral currents. To that aim, we start by assessing the necessary calculations on the hadronic, nuclear and atomic/molecular level, deriving expressions with conservative error estimates. Their phenomenological analysis in the context of two-Higgs-doublet models yields strong constraints, in some cases weakened by a cancellation mechanism among contributions from neutral scalars. While the corresponding parameter combinations do not yet have to be unnaturally small, the constraints are likely to preclude large effects in other CP-violating observables. Nevertheless, the generically expected contributions to electric dipole moments in this class of models lie within the projected sensitivity of the next-generation experiments.

Effective Lagrangian description of Higgs mediated flavor violating electromagnetic transitions: Implications on lepton flavor violation

2009-01-01

Higgs mediated flavor violating electromagnetic interactions, induced at the one-loop level by a nondiagonal Hf i f j vertex, with f i and f j charged leptons or quarks, are studied within the context of a completely general effective Yukawa sector that comprises SU L (2)xU Y (1)-invariant operators of up to dimension-six. Exact formulae for the one-loop γf i f j and γγf i f j couplings are presented and their related processes used to study the phenomena of Higgs mediated lepton flavor violation. The experimental limit on the μ→eγ decay is used to derive a bound on the branching ratio of the μ→eγγ transition, which is 6 orders of magnitude stronger than the current experimental limit. Previous results on the τ→μγ and τ→μγγ decays are reproduced. The possibility of detecting signals of lepton flavor violation at γγ colliders is explored through the γγ→l i l j reaction, putting special emphasis on the τμ final state. Using the bound imposed on the Hτμ vertex by the current experimental data on the muon anomalous magnetic moment, it is found that about half a hundred events may be produced in the International Linear Collider.

Is the Weinberg model of CP violation really excluded?

International Nuclear Information System (INIS)

Cheng, H.

1990-01-01

We give an updated analysis on various CP-violating effects in the Weinberg three-Higgs-doublet model of CP violation. Because of the improved estimate of the η-η' mixing and of the K-η 0 transition, the sign of ε'/ε is predicted to be the same as that of the chiral suppression of CP-odd K→2π amplitudes (owing to the presence of tadpole contributions) and is most likely to be positive, contrary to previous calculations. The neutron electric dipole moment d n due to neutral-Higgs-boson exchange at the one-loop level is reexamined and is found to be below the present experimental limit for reasonable Higgs-boson mass. However, the Weinberg's three-gluon operator arising from charged-Higgs-boson exchange will produce an excessive d n even if the charged Higgs bosons are uncomfortably light. We conclude that the Weinberg CP-violation model is not necessarily inconsistent with experiment of measuring ε'/ε, but it tends to give too large a value of d n

A powerful tool for measuring Higgs boson associated Lepton Flavour Violation

In models with extended Higgs sectors, Higgs-boson-mediated Lepton Flavour Violation (LFV) can naturally appear. We study the physics potential of an electron-photon collider on searching LFV processes e - γ → l - φ (l = μ, τ;φ = H,A) where H and A are extra CP even and odd Higgs bosons, respectively, in the minimal supersymmetric standard model and the effective two Higgs doublet model. The production cross section can be significantly large for the maximal allowed values of the LFV coupling constants under the current experimental data. Present experimental upper bounds on the effective LFV coupling constants would be considerably improved by searching these processes, which would be better than MEG and COMET experiments and also those at LHCb and SuperKEKB. Moreover, one can separately measure chirality of effective LFV coupling constants via these processes by selecting electron polarizations. (author)

Production of heavy neutral MSSM Higgs boson in photon-electron colliders

International Nuclear Information System (INIS)

Mahmoud, I.S.H.

2004-01-01

The production of heavy neutral Higgs boson has been studied through all the possible three out states processes by using the minimal supersymmetric standard model (MSSM) in the photon - electron colliders. The Feynman diagrams have been drawing for each possible mode of the interaction. The total cross section as a function of center of mass energy has been calculated for each process. It has been found that, the most dominant process occurs when the heavy neutral Higgs boson (Hο) produces with e-neutrino (v e ) and the negative charged Higgs boson (H - ) at centre of mass energy -√s≡ 1430 GeV at a value of the order ≅ 1.0 x 10 -4 pbarn

Current densities in a space-time-dependent and CP-violating Higgs background in the adiabatic limit

Comelli, D.; Pietroni, M.; Riotto, A.

1996-01-01

Motivated by cosmological applications such as electroweak baryogenesis, we develop a field theoretic approach to the computation of particle currents on a space-time-dependent and CP-violating Higgs background in the adiabatic limit. We consider the standard model with two Higgs doublets and CP violation in the scalar sector, and compute both fermionic and Higgs currents by means of an expansion in the background fields describing the profile of the bubble wall. We discuss the gauge dependence of the results and the renormalization of the current operators, showing that in the limit of local equilibrium, no extra renormalization conditions are needed in order to specify the system completely. copyright 1996 The American Physical Society

On the Flavor Structure of Natural Composite Higgs Models & Top Flavor Violation

CERN Document Server

Azatov, Aleksandr; Perez, Gilad; Soreq, Yotam

2014-01-01

We explore the up flavor structure of composite pseudo Nambu-Goldstone-boson Higgs models, where we focus on the flavor anarchic minimal $SO(5)$ case. We identify the different sources of flavor violation in this framework and emphasise the differences from the anarchic Randall-Sundrum scenario. In particular, the fact that the flavor symmetry does not commute with the symmetries that stabilize the Higgs potential may constrain the flavor structure of the theory. In addition, we consider the interplay between the fine tuning of the model and flavor violation. We find that generically the tuning of this class of models is worsen in the anarchic case due to the contributions from the additional fermion resonances. We show that, even in the presence of custodial symmetry, large top flavor violating rate are naturally expected. In particular, $t\\to cZ$ branching ratio of order of $10^{-5}$ is generic for this class of models. Thus, this framework can be tested in the next run of the LHC as well as in other future...

Lorentz-violating alternative to the Higgs mechanism?

International Nuclear Information System (INIS)

Alexandre, Jean; Mavromatos, Nick E.

2011-01-01

We consider a four-dimensional field-theory model with two massless fermions, coupled to an Abelian vector field without flavor mixing, and to another Abelian vector field with flavor mixing. Both Abelian vectors have a Lorentz-violating kinetic term, introducing a Lorentz-violation mass scale M, from which fermions and the flavor-mixing vector get their dynamical masses, whereas the vector coupled without flavor mixing remains massless. When the two coupling constants have similar values in order of magnitude, a mass hierarchy pattern emerges, in which one fermion is very light compared to the other, while the vector mass is of the order of the heavy fermion mass. The work presented here may be considered as a Lorentz-symmetry-violating alternative to the Higgs mechanism, in the sense that no scalar particle (fundamental or composite) is necessary for the generation of the vector-meson mass. However, the model is not realistic given that, as a result of Lorentz violation, the maximal (light-cone) speed seen by the fermions is smaller than that of the massless gauge boson (which equals the speed of light in vacuo) by an amount which is unacceptably large to be compatible with the current tests of Lorentz invariance, unless the gauge couplings assume unnaturally small values. Possible ways out of this phenomenological drawback are briefly discussed, postponing a detailed construction of more realistic models for future work.

Naturally large radiative lepton flavor violating Higgs decay mediated by lepton-flavored dark matter

International Nuclear Information System (INIS)

Baek, Seungwon; Kang, Zhaofeng

2016-01-01

In the standard model (SM), lepton flavor violating (LFV) Higgs decay is absent at renormalizable level and thus it is a good probe to new physics. In this article we study a type of new physics that could lead to large LFV Higgs decay, i.e., a lepton-flavored dark matter (DM) model which is specified by a Majorana DM and scalar lepton mediators. Different from other similar models with similar setup, we introduce both left-handed and right-handed scalar leptons. They allow large LFV Higgs decay and thus may explain the tentative Br(h→τμ)∼1% experimental results from the LHC. In particular, we find that the stringent bound from τ→μγ can be naturally evaded. One reason, among others, is a large chirality violation in the mediator sector. Aspects of relic density and especially radiative direct detection of the leptonic DM are also investigated, stressing the difference from previous lepton-flavored DM models.

Particle currents on a CP violating Higgs background and the spontaneous baryogenesis mechanism

International Nuclear Information System (INIS)

Comelli, D.; Riotto, A.

1995-04-01

We compute the particle currents induced on a bubble wall background at finite temperature in a model with CP violation in the Higgs sector. Using a field theory approach we show that fermionic currents arise at one loop, so that a suppression factor OMIKRON (h t φ/πT) 2 with respect to previous computations is found. The contributions to the Higgs currents are also derived and their relevancy for the spontaneous baryogenesis mechanism is discussed. (orig.)

CP violation in neutral B decays to non-CP-eigenstates

International Nuclear Information System (INIS)

Kayser, B.

1992-01-01

If CP violation comes from complex phases in the quark mixing matrix, then neutral B decays to CP eigenstates will exhibit large, cleanly-predicted CP-violating effects. The authors show that the same is true of neutral B decays to several types of ''near-CP-eigenstates.'' By experimentally studying the latter decays as well as those to the CP eigenstates, one will be able to obtain more definitive information on CP violation from a given number of B mesons

Searches for neutral Higgs bosons produced at LEP in association with Z bosons, in pairs and in the Yukawa process are presented in this paper. Higgs boson decays into b quarks, tau leptons, or other Higgs bosons are considered, giving rise to four-b, four-b+jets, six-b and four-tau final states, as well as mixed modes with b quarks and tau leptons. The whole mass domain kinematically accessible at LEP in these topologies is searched. The analysed data set covers both the LEP1 and LEP2 energy ranges and exploits most of the luminosity recorded by the DELPHI experiment. No convincing evidence for a signal is found, and results are presented in the form of mass-dependent upper bounds on coupling factors (in units of model-independent reference cross-sections) for all processes, allowing interpretation of the data in a large class of models.

The Next-to-Minimal Supersymmetric Standard model (NMSSM) appears as an interesting candidate for the interpretation of the Higgs measurement at the LHC and as a rich framework embedding physics beyond the Standard Model. We consider the renormalization of the Higgs sector of this model in its CP-violating version, and propose a renormalization scheme for the calculation of on-shell Higgs masses. Moreover, the connection between the physical states and the tree-level ones is no longer trivial at the radiative level: a proper description of the corresponding transition thus proves necessary in order to calculate Higgs production and decays at a consistent loop order. After discussing these formal aspects, we compare the results of our mass calculation to the output of existing tools. We also study the relevance of the on-shell transition matrix in the example of the h{sub i} → τ{sup +}τ{sup -} width. We find deviations between our full prescription and popular approximations that can exceed 10%. (orig.)

Are Higgs particles strongly interacting(question mark)

International Nuclear Information System (INIS)

Shanker, O.

1982-02-01

The order of magnitude of Yukawa couplings in some theories with flavour violating Higgs particles is estimated. Based on these couplings, mass bounds for flavour violating Higgs particles are derived from the Ksub(L)-Ksub(S) mass difference. The Higgs particles have to be very heavy, implying that the Higgs sector quartic couplings are very large. Thus, these theories seem to require a strongly interacting Higgs sector unless one adjusts to the Higgs-fermion Yukawa couplings to within two orders of magnitude, so as to suppress the coupling of Higgs particles to the flavour-violating anti sd current. Most models with flavour violating Higgs particles have the same general features, so the conclusions are likely to hold for a wide class of models with flavour violating Higgs particles

Spontaneous C P -violation in the simplest little Higgs model and its future collider tests: The scalar sector

Science.gov (United States)

Mao, Ying-nan

2018-04-01

We propose spontaneous C P violation in the simplest little Higgs model. In this model, the pseudoscalar field can acquire a nonzero vacuum expectation value. This leads to a mixing between the two scalars with different C P charge, which means that spontaneous C P violation occurs. It is also a connection between the composite Higgs mechanism and C P violation. Facing the experimental constraints, the model is still viable for both scenarios in which the extra scalar appears below or around the electroweak scale. We also discuss the future collider tests of C P violation in the scalar sector through measuring h2Z Z and h1h2Z' vertices (see the definitions of the particles in the text), which provide new motivations for future e+e- and p p colliders. This also shows the importance of the vector-vector-scalar- and vector-scalar-scalar-type vertices in discovering C P -violation effects in the scalar sector.

Neutral Supersymmetric Higgs Boson Searches

Energy Technology Data Exchange (ETDEWEB)

Robinson, Stephen Luke [Imperial College, London (United Kingdom)

2008-07-01

In some Supersymmetric extensions of the Standard Model, including the Minimal Supersymmetric Standard Model (MSSM), the coupling of Higgs bosons to b-quarks is enhanced. This enhancement makes the associated production of the Higgs with b-quarks an interesting search channel for the Higgs and Supersymmetry at D0. The identification of b-quarks, both online and offline, is essential to this search effort. This thesis describes the author's involvement in the development of both types of b-tagging and in the application of these techniques to the MSSM Higgs search. Work was carried out on the Level-3 trigger b-tagging algorithms. The impact parameter (IP) b-tagger was retuned and the effects of increased instantaneous luminosity on the tagger were studied. An extension of the IP-tagger to use the z-tracking information was developed. A new b-tagger using secondary vertices was developed and commissioned. A tool was developed to allow the use of large multi-run samples for trigger studies involving b-quarks. Offline, a neural network (NN) b-tagger was trained combining the existing offline lifetime based b-tagging tools. The efficiency and fake rate of the NN b-tagger were measured in data and MC. This b-tagger was internally reviewed and certified by the Collaboration and now provides the official b-tagging for all analyses using the Run IIa dataset at D0. A search was performed for neutral MSSM Higgs bosons decaying to a b{bar b} pair and produced in association with one or more b-quarks. Limits are set on the cross-section times the branching ratio for such a process. The limits were interpreted in various MSSM scenarios. This analysis uses the NN b-tagger and was the first to use this tool. The analysis also relies on triggers using the Level-3 IP b-tagging tool described previously. A likelihood discriminant was used to improve the analysis and a neural network was developed to cross-check this technique. The result of the analysis has been submitted to PRL

Phenomenological viability of orbifold models with three Higgs families

International Nuclear Information System (INIS)

Escudero, Nicolas; Munoz, Carlos; Teixeira, Ana M.

2006-01-01

We discuss the phenomenological viability of string multi-Higgs doublet models, namely a scenario of heterotic Z 3 orbifolds with two Wilson lines, which naturally predicts three supersymmetric families of matter and Higgs fields. We study the orbifold parameter space, and discuss the compatibility of the predicted Yukawa couplings with current experimental data. We address the implications of tree-level flavour changing neutral processes in constraining the Higgs sector of the model, finding that viable scenarios can be obtained for a reasonably light Higgs spectrum. We also take into account the tree-level contributions to indirect CP violation, showing that the experimental value of ε K can be accommodated in the present framework

Equivalence principle, CP violations, and the Higgs-like boson mass

We consider the violation of the equivalence principle induced by a massive gravivector, i.e., the partner of the graviton in N>1 supergravity. The present limits on this violation allow us to obtain a lower bound on the vacuum expectation value of the scalar field that gives the gravivector its mass. We consider also the effective neutral kaon mass difference induced by the gravivector and compare the result with the experimental data on the CP-violation parameter ε

Leptophilic neutral Higgs bosons in two Higgs doublet model at a linear collider

Energy Technology Data Exchange (ETDEWEB)

Hashemi, Majid [Shiraz University, Physics Department, College of Sciences, Shiraz (Iran, Islamic Republic of)

2017-05-15

This paper addresses the question of the observability of neutral Higgs bosons through the leptonic decay in a two Higgs doublet model (2HDM). Both scalar and pseudo-scalar Higgs bosons (H, A) are considered. The model is set to type IV to enhance the leptonic decay. In such a scenario, a signal production process like e{sup +}e{sup -} → A{sup 0}H{sup 0} → ττμμ or μμττ would provide a clear signal on top of the background in a di-muon invariant mass distribution far from the Z boson pole mass. The analysis is based on a τ-id algorithm which preselects events if they have two τ jets by requiring a hadronic τ decay. Several benchmark points are defined for the search, requiring a linear collider operating at √(s) = 0.5 and 1 TeV. It is shown that the signal can be observed on top of the background in all benchmark points at an integrated luminosity of 1000 fb{sup -1}. (orig.)

Phenomenology of SU(5 low-energy realizations: The diphoton excess and Higgs flavor violation

Directory of Open Access Journals (Sweden)

Andrea Di Iura

2016-10-01

Full Text Available We discuss different SU(5 low-energy realizations and illustrate their use with the diphoton excess and Higgs flavor violation, which require new physics at the TeV scale. In particular, we study two scenarios for a 750 GeV resonance: in the first one the resonance belongs to the adjoint of SU(5, being either an SU(2L singlet or a triplet, while in the second case the signal is due to the CP-even and CP-odd states of a new SU(2L Higgs doublet belonging to a 45H or a 70H representations, giving rise to a two-Higgs doublet model at low energies. We study the fine-tuning needed for the desired members of the multiplets to be light enough, while having the rest at the GUT scale. In these scenarios, the production and decay into photons of the new resonance are mediated by the leptoquarks (LQ present in these large SU(5 representations. We analyze the phenomenology of such scenarios, focusing on the most relevant predictions that can help to disentangle the different models, like decays into gauge bosons, Standard Model (SM fermions and LQs pair production. In the case of the 45H (the Georgi–Jarlskog model, we also study the possibility to have Higgs flavor violation. We find that Bs mixing limits (in addition to τ→μγ always imply that Br(h→τμ,bs≲10−5.

We study the prospective sensitivity to C P -violating two Higgs doublet models from the 14 TeV LHC and future electric dipole moment (EDM) experiments. We concentrate on the search for a resonant heavy Higgs that decays to a Z boson and a SM-like Higgs h , leading to the Z (ℓℓ)h (b b ¯ ) final state. The prospective LHC reach is analyzed using the Boosted Decision Tree method. We illustrate the complementarity between the LHC and low energy EDM measurements and study the dependence of the physics reach on the degree of deviation from the alignment limit. In all cases, we find that there exists a large part of parameter space that is sensitive to both EDMs and LHC searches.

Discriminating between Higgs Boson models using e+e- → tt-bar h and Zh at the NLC

In extensions of the Standard Model (SM) there are multiple neutral Higgs bosons. Their masses and couplings are often dependent upon many parameters; CP-violating mixing of CP-even with CP-odd neutral Higgs fields is generally possible. It is demonstrated that the process e + e - → tt-bar h at the NLC provides a powerful tool for extracting the tt-bar (Yukawa) couplings of the h. In combination with the e + e - → Zh process, an accurate determination of the ZZ coupling of the H is also possible. The resulting ability to distinguish different models of the Higgs sector is illustrated by detailed studies for two-Higgs-doublet models, for which the masses and couplings of the three neutral Higgs bosons are all free parameters. It is concluded that it is very possible that the SM is not correct. In this case, and if there is a weakly-coupled Higgs sector, there will certainly be Higgs bosons that do not have SM-like couplings. 3 refs., 3 figs

We study a class of models in which the Higgs pair production is enhanced at hadron colliders by an extra neutral scalar. The scalar particle is produced by the gluon fusion via a loop of new colored particles, and decays into di-Higgs through its mixing with the Standard Model Higgs. Such a colored particle can be the top/bottom partner, such as in the dilaton model, or a colored scalar which can be triplet, sextet, octet, etc., called leptoquark, diquark, coloron, etc., respectively. We examine the experimental constraints from the latest Large Hadron Collider (LHC) data, and discuss the future prospects of the LHC and the Future Circular Collider up to 100 TeV. We also point out that the 2.4σ excess in the b anti bγγ final state reported by the ATLAS experiment can be interpreted as the resonance of the neutral scalar at 300 GeV. (orig.)

A search for neutral Higgs bosons decaying to tau pairs at a center-of-mass energy of 7 TeV is performed using a dataset corresponding to an integrated luminosity of 4.6 inverse femtobarns recorded by the CMS experiment at the LHC. The search is sensitive to both the standard model Higgs boson and to the neutral Higgs bosons predicted by the minimal supersymmetric extension of the standard model (MSSM). No excess of events is observed in the tau-pair invariant-mass spectrum. For a standard model Higgs boson in the mass range of 110-145 GeV upper limits at 95% confidence level (CL) on the production cross section are determined. We exclude a Higgs boson with m(H)=115 GeV with a production cross section 3.2 times of that predicted by the standard model. In the MSSM, upper limits on the neutral Higgs boson production cross section times branching fraction to tau pairs, as a function of the pseudoscalar Higgs boson mass, m(A), sets stringent new bounds in the parameter space, excluding at 95% CL values of tan(bet...

We study lepton violating Higgs (HLFV) decays, first from the effective field theory (EFT) point of view, and then analysing the different high-energy realizations of the operators of the EFT, highlighting the most promising models. We argue why two Higgs doublet models can have a BR(h→τμ)∼0.01, and why this rate is suppressed in all other realizations including vector-like leptons. We further discuss HLFV in the context of neutrino mass models: in most cases it is generated at one loop giving always BR(h→τμ)<10{sup −4} and typically much less, which is beyond experimental reach. However, both the Zee model and extended left-right symmetric models contain extra SU(2) doublets coupled to leptons and could in principle account for the observed excess, with interesting connections between HLFV and neutrino parameters.

The Higgs boson is the last undiscovered particle predicted by the Standard Model. Its discovery is key to our understanding of the electroweak symmetry breaking process and the origin of mass. The primary purpose of the ATLAS detector at the Large Hadron Collider is the discovery of this particle. This thesis evaluates the discovery potential of the ATLAS experiment for a Heavy Neutral Scalar Higgs boson, $\\text{M}_{H} \\ge 170 ~\\text{\\GEVCC}$, produced through vector boson fusion and decaying through the four physics channels : H$\\rightarrow$ZZ$\\rightarrow l^{+}l^{-}$+jj and H$\\rightarrow$WW$\\rightarrow l\

Two Higgs Bosons near 125 GeV in the Complex NMSSM and the LHC Run I Data

We analyse the impact of explicit CP-violation in the Higgs sector of the Next-to-Minimal Supersymmetric Standard Model (NMSSM) on its consistency with the Higgs boson data from the Large Hadron Collider (LHC). Through detailed scans of the parameter space of the complex NMSSM for certain fixed values of one of its CP-violating (CPV) phases, we obtain a large number of points corresponding to five phenomenologically relevant scenarios containing ∼125 GeV Higgs boson(s). We focus, in particular, on the scenarios where the visible peaks in the experimental samples can actually be explained by two nearly mass-degenerate neutral Higgs boson states. We find that some points corresponding to these scenarios give an overall slightly improved fit to the data, more so for nonzero values of the CPV phase, compared to the scenarios containing a single Higgs boson near 125 GeV

We discuss Higgs boson decays in the CP-violating MSSM, and examine their phe- nomenological impact using cross section limits from the LEP Higgs searches. This includes a discussion of the full 1-loop results for the partial decay widths of neutral Higgs bosons into lighter neutral Higgs bosons (h{sub a}{yields}h{sub b}h{sub c}) and of neutral Higgs bosons into fermions (h{sub a}{yields}f anti f). In calculating the genuine vertex corrections, we take into account the full spectrum of supersymmetric particles and all complex phases of the supersymmetric parameters. These genuine vertex corrections are supplemented with Higgs propagator corrections incorporating the full one-loop and the dominant two-loop contributions, and we illustrate a method of consistently treating diagrams involving mixing with Goldstone and Z bosons. In particular, the genuine vertex corrections to the process h{sub a}{yields}h{sub b}h{sub c} are found to be very large and, where this process is kinematically allowed, can have a significant effect on the regions of the CPX bench- mark scenario which can be excluded by the results of the Higgs searches at LEP. However, there remains an unexcluded region of CPX parameter space at a lightest neutral Higgs boson mass of {proportional_to}45 GeV. In the analysis, we pay particular attention to the conversion between parameters defined in different renormalisation schemes and are therefore able to make a comparison to the results found using renormalisation group improved/effective potential calculations.

Search for Neutral MSSM Higgs bosons decaying to tau pairs in the ATLAS experiment

CERN Multimedia

Scutti, F

2013-01-01

The Minimal Supersymmetric Standard Model (MSSM) is a supersymmetric extension of the Standard Model of particle physics, predicting the existence of five Higgs bosons, two charged (H±) and three neutral (h, H, A). At tree level their properties are determined by two independent parameters: the mass of the CP-odd Higgs boson mA, and the ratio between the vacuum expectation values of the two Higgs doublets predicted tan(beta). In Supersymmetric models, the Higgs boson couplings to down-type fermions like b-quarks or tau leptons is significantly enhanced over a large region of the parameter space. Decays to tau lepton pairs occur 10% of the times and provide a cleaner environment for the search than decays to b-quarks. The tau lepton can decay into either a muon or an electron, plus neutrinos, or in hadrons plus neutrinos. In this poster, the search for the heavy neutral MSSM Higgses (h, H, A) is presented, where the final state is a pair of hadronically decaying tau leptons. This channel provides good sensit...

Lepton flavor violating decays τ→lll and μ→eγ in the Higgs triplet model

International Nuclear Information System (INIS)

Akeroyd, A. G.; Aoki, Mayumi; Sugiyama, Hiroaki

2009-01-01

Singly and doubly charged Higgs bosons in the Higgs triplet model mediate the lepton flavor violating (LFV) decays τ→lll and μ→eγ. The lepton flavor violating decay rates are proportional to products of two triplet Yukawa couplings (h ij ) which can be expressed in terms of the parameters of the neutrino mass matrix and an unknown triplet vacuum expectation value. We determine the parameter space of the neutrino mass matrix in which a signal for τ→lll and/or μ→eγ is possible at ongoing and planned experiments. The conditions for respecting the stringent upper limit for μ→eee are studied in detail, with emphasis given to the possibility of |h ee |≅0, which can only be realized if Majorana phases are present.

Phenomenological comparison of models with extended Higgs sectors

Beyond the Standard Model (SM) extensions usually include extended Higgs sectors. Models with singlet or doublet fields are the simplest ones that are compatible with the ρ parameter constraint. The discovery of new non-SM Higgs bosons and the identification of the underlying model requires dedicated Higgs properties analyses. In this paper, we compare several Higgs sectors featuring 3 CP-even neutral Higgs bosons that are also motivated by their simplicity and their capability to solve some of the flaws of the SM. They are: the SM extended by a complex singlet field (C x SM), the singlet extension of the 2-Higgs-Doublet Model (N2HDM), and the Next-to-Minimal Supersymmetric SM extension (NMSSM). In addition, we analyse the CP-violating 2-Higgs-Doublet Model (C2HDM), which provides 3 neutral Higgs bosons with a pseudoscalar admixture. This allows us to compare the effects of singlet and pseudoscalar admixtures. Through dedicated scans of the allowed parameter space of the models, we analyse the phenomenologically viable scenarios from the view point of the SM-like Higgs boson and of the signal rates of the non-SM-like Higgs bosons to be found. In particular, we analyse the effect of singlet/pseudoscalar admixture, and the potential to differentiate these models in the near future. This is supported by a study of couplings sums of the Higgs bosons to massive gauge bosons and to fermions, where we identify features that allow us to distinguish the models, in particular when only part of the Higgs spectrum is discovered. Our results can be taken as guidelines for future LHC data analyses, by the ATLAS and CMS experiments, to identify specific benchmark points aimed at revealing the underlying model.

Beyond the Standard Model (SM) extensions usually include extended Higgs sectors. Models with singlet or doublet fields are the simplest ones that are compatible with the ρ parameter constraint. The discovery of new non-SM Higgs bosons and the identification of the underlying model requires dedicated Higgs properties analyses. In this paper, we compare several Higgs sectors featuring 3 CP-even neutral Higgs bosons that are also motivated by their simplicity and their capability to solve some of the flaws of the SM. They are: the SM extended by a complex singlet field (C x SM), the singlet extension of the 2-Higgs-Doublet Model (N2HDM), and the Next-to-Minimal Supersymmetric SM extension (NMSSM).

Minimal flavour violation in the quark and lepton sector and the impact of extra dimensions on flavour changing neutral currents and electroweak symmetry breaking

2007-01-01

We study flavor-changing decays of hadrons and leptons and an extra-dimensional approach to electroweak symmetry breaking. Specifically we study the framework of Minimal Flavour Violation (MFV) as an explanation of the flavour problem. We discuss the impact of a specific extra-dimensional model of the MFV class on flavour changing neutral currents. We derive model-independent upper bounds on rare decays. -We discuss the extension of the MFV framework from the quark to the lepton sector and show how baryogenesis through leptogenesis can be achieved and examine if possible correlations with charged lepton flavour violation exist. We discuss the dynamical breaking of the electroweak symmetry in extra dimensions by unifying gauge and Higgs fields and we show that realistic models are possible once the extra dimension is strongly curved.

Complex parameters in the MSSM lead to mixing and interference between the two heavier neutral CP-even and CP-odd Higgs states. These effects can become very large in the case of almost degenerate states. In a CP-violating benchmark scenario, we investigate phenomenological implications of such interferences in view of the LHC searches for heavy Higgs bosons decaying to a pair of τ-leptons and produced in gluon fusion and in association with b-quarks. Strongly destructive effects leave parameter regions unconstrained that would be regarded as excluded if no interference terms were taken into account.

Difficulties for a simple picture of spontaneous CP violation

We show that vertical stroke epsilon'/epsilon vertical stroke is unacceptably large in SU(2)sub(L) x U(1) models with spontaneous CP violation and natural flavor conservation in neutral Higgs-particle interactions if it is assumed that charmed quark intermediate states contribute significantly and that Msub(W) 2 >> Msub(H) 2 >> Msub(C) 2 . From the quark operator structure of box and penguin graphs involving Higgs-particle exchange, we demonstrate that pseudoscalar current matrix elements cannot be enhanced over axial-current matrix elements as has been previously assumed in similar calculations. Alternate ways to evaluate the matrix elements are employed. (orig.)

A search for neutral Higgs bosons in the minimal supersymmetric extension of the standard model (MSSM) decaying to tau-lepton pairs in pp collisions is performed, using events recorded by the CMS experiment at the LHC. The dataset corresponds to an integrated luminosity of 24.6 fb-1, with 4.9 fb-1 at 7 TeV and 19.7 fb-1 at 8 TeV. To enhance the sensitivity to neutral MSSM Higgs bosons, the search includes the case where the Higgs boson is produced in association with a b-quark jet. No excess is observed in the tau-lepton-pair invariant mass spectrum. Exclusion limits are presented in the MSSM parameter space for different benchmark scenarios, m {h/max}, m {h/mod +}, m {h/mod -}, light-stop, light-stau, τ-phobic, and low- m H. Upper limits on the cross section times branching fraction for gluon fusion and b-quark associated Higgs boson production are also given. [Figure not available: see fulltext.

A search for neutral Higgs bosons in the minimal supersymmetric extension of the standard model (MSSM) decaying to tau-lepton pairs in pp collisions is performed, using events recorded by the CMS experiment at the LHC. The dataset corresponds to an integrated luminosity of 24.6 fb$^{-1}$, with 4.9 fb$^{-1}$ at 7 TeV and 19.7 fb$^{-1}$ at 8 TeV. To enhance the sensitivity to neutral MSSM Higgs bosons, the search includes the case where the Higgs boson is produced in association with a b-quark jet. No excess is observed in the tau-lepton-pair invariant mass spectrum. Exclusion limits are presented in the MSSM parameter space for different benchmark scenarios, $m_\\mathrm{h}^\\text{max}$, $m_\\mathrm{h}^{\\text{mod}+}$, $m_\\mathrm{h}^{\\text{mod}-}$, light-stop, light-stau, $\\tau$-phobic, and low-$m_\\mathrm{H}$. Upper limits on the cross section times branching fraction for gluon fusion and b-quark associated Higgs boson production are also given.

On the phenomenology of charged Higgs bosons in the complex MSSM

2012-02-16

In this thesis, we study various decay and production processes of charged Higgs bosons at the Large Hadron Collider (LHC) in the context of a general complex Minimal Supersymmetric Standard Model (MSSM) with minimal flavor violation. We investigate the effect of the complex phases of the soft supersymmetry breaking parameters and of the Higgsino mixing parameter, {mu}, on the decay widths and production rates. The CP violating asymmetries induced by those phases are also considered. The calculations are done at the one-loop level. This is nontrivial since there are a large number of Feynman diagrams and various types of singularities (UV divergences, soft and collinear singularities, threshold singularities). We discuss in detail our calculation method and how to handle those divergences. In particular, the topic of one-loop renormalization and neutral-Higgs mixing effects in the complex MSSM for processes involving Higgs bosons are addressed. The higher order corrections to the decay of charged Higgs bosons into aW-boson and the lightest neutral Higgs boson are calculated and shown to be significantly large. The CP asymmetry arising from all complex phases is considered, especially from the top-quark trilinear coupling, A{sub t}, and {mu}, which induce a large contribution to the CP asymmetry. We perform a complete calculation of the next-to-leading order (NLO) electroweak (EW) corrections to the charged Higgs production in association with a W-boson via the bb annihilation channel and a consistent combination with other contributions including the standard and supersymmetric-QCD corrections and the gg fusion, with resummation of the leading radiative corrections to the bottom-Higgs couplings and the neutral Higgs-boson propagators. We observe a strong dependence of the production rates on the phases of A{sub t} and of the gluino-mass parameter M{sub 3} and a large CP asymmetry arising mainly from the gg fusion. The NLO EW corrections to the charged Higgs

Higgs boson flavor-changing neutral decays into bottom quarks in supersymmetry

We analyze the maximum branching ratios for the Flavor Changing Neutral Current (FCNC) decays of the neutral Higgs bosons of the Minimal Supersymmetric Standard Model (MSSM) into bottom quarks, h→bs-bar h=h 0 ,H 0 , A 0 ). We consistently correlate these decays with the radiative B-meson decays (b→sγ). A full-fledged combined numerical analysis is performed of these high-energy and low-energy FCNC decay modes in the MSSM parameter space. Our calculation shows that the available data on B(b→sγ) severely restricts the allowed values of B(h→bs-bar). While the latter could reach a few percent level in fine-tuned scenarios, the requirement of naturalness reduces these FCNC rates into the modest range B(h→bs-bar) ∼ 10 -4 -10 -3 . We find that the bulk of the MSSM contribution to B(h→bs-bar) could originate from the strong supersymmetric sector. The maximum value of the FCNC rates obtained in this paper disagree significantly with recent (over-)estimates existing in the literature. Our results are still encouraging because they show that the FCNC modes h→bs-bar can be competitive with other Higgs boson signatures and could play a helpful complementary role to identify the supersymmetric Higgs bosons, particularly the lightest CP-even state in the critical LHC mass region m h 0 approx. = 90-130 GeV.

Lepton flavour violation in RS models with a brane- or nearly brane-localized Higgs

We perform a comprehensive study of charged lepton flavour violation in Randall-Sundrum (RS) models in a fully 5D quantum-field-theoretical framework. We consider the RS model with minimal field content and a ;custodially protected; extension as well as three implementations of the IR-brane localized Higgs field, including the non-decoupling effect of the KK excitations of a narrow bulk Higgs. Our calculation provides the first complete result for the flavour-violating electromagnetic dipole operator in Randall-Sundrum models. It contains three contributions with different dependence on the magnitude of the anarchic 5D Yukawa matrix, which can all be important in certain parameter regions. We study the typical range for the branching fractions of μ → eγ, μ → 3 e, μN → eN as well as τ → μγ, τ → 3 μ and the electron electric dipole moment by a numerical scan in both the minimal and the custodial RS model. The combination of μ → eγ and μN → eN currently provides the most stringent constraint on the parameter space of the model. A typical lower limit on the KK scale T is around 2 TeV in the minimal model (up to 4 TeV in the bulk Higgs case with large Yukawa couplings), and around 4 TeV in the custodially protected model, which corresponds to a mass of about 10 TeV for the first KK excitations, far beyond the lower limit from the non-observation of direct production at the LHC.

2015-01-01

The recent measurement of Higgs boson properties, cross section, spin-parity and non-standard model coupling (Lepton flavor violation, flavor changing neutral current), in the ATLAS and CMS experiments are reported. The total cross section is $33.0\\pm5.3(stat.)\\pm1.6(sys.)$pb, that is agreement with state-of-art theory predictions. The differential cross sections of several variables are also fair agreement with theory predictions. Various hypothesis tests for spin $1^{\\pm}$ and $2^{\\pm}$ scenarios has been performed. No indication favors spin 1 or 2 models has been observed. CP-mixing scenarios for spin 0 have been investigated. No significant deviation from the Standard Model $0^{+}$ has been observed. We also searched for anomalous couplings, the lepton flavor violating decay in $H\\rightarrow \\mu\\tau$ events and flavor changing neutral current in $t\\rightarrow qH$ events. No significant excess has been observed in LHC Run-I data.

We consider the Minimal Supersymmetric extension of the Standard Model in the regime where the supersymmetric breaking scale is extremely large. In this MSSM, not only the Higgs masses will be affected by large radiative corrections, the dominant part of which is provided by the third generation quark/squark sector, but also the various self-couplings among the Higgs states. In this note, assuming that squarks are extremely heavy, we evaluate the next-to-leading order radiative corrections to the two neutral CP-even Higgs self-couplings λHhh and λhhh and to the partial decay width Γ (H → hh) that are most relevant at the LHC. The calculation is performed using an effective field theory approach that resums the large logarithmic squark contributions and allows to keep under control the perturbative expansion. Since the direct loop vertex corrections are generally missing in this effective approach, we have properly renormalised the effective theory to take them into account. Finally, we perform a comparison of the results in this effective MSSM with those obtained in a much simpler way in the so-called hMSSM approach in which the mass value for the lightest Higgs boson Mh = 125 GeV is used as an input. We show that the hMSSM provides a reasonably good approximation of the corrected self-couplings and H → hh decay rate and, hence, it can be used also in these cases.

Higgs-Mediated Electric Dipole Moments in the MSSM An Application to Baryogenesis and Higgs Searches

Pilaftsis, Apostolos

2002-01-01

We perform a comprehensive study of the dominant two- and higher-loop contributions to the Tl(205), neutron and muon electric dipole moments induced by Higgs bosons, third-generation quarks and squarks, charginos and gluinos in the Minimal Supersymmetric Standard Model (MSSM). We find that strong correlations exist among the contributing CP-violating operators, for large stop, gluino and chargino phases, and for a wide range of values of \\tan\\beta and charged Higgs-boson masses, giving rise to large suppressions of the Tl(205) and neutron electric dipole moments below their present experimental limits. Based on this observation, we discuss the constraints that the nonobservation of electric dipole moments imposes on the radiatively-generated CP-violating Higgs sector and on the mechanism of electroweak baryogenesis in the MSSM. We improve previously suggested benchmark scenarios of maximal CP violation for analyzing direct searches of CP-violating MSSM Higgs-bosons at high-energy colliders, and stress the imp...

Searches for neutral Higgs bosons are performed with the 237 pb^-1 of data collected in 1999 by the ALEPH detector at LEP, for centre-of-mass energies between 191.6 and 201.6 GeV. These searches apply to Higgs bosons within the context of the Standard Model and its minimal supersymmetric extension (MSSM) as well as to invisibly decaying Higgs bosons. No evidence of a signal is seen. A lower limit on the mass of the Standard Model Higgs boson of 107.7 GeV/c^2 at 95% confidence level is set. In the MSSM, lower limits of 91.2 and 91.6 GeV/c^2 are derived for the masses of the neutral Higgs bosons h and A, respectively. For a Higgs boson decaying invisibly and produced with the Standard Model cross section, masses below 106.4 GeV/c^2 are excluded.

Interference effects of neutral MSSM Higgs bosons with a generalised narrow-width approximation

International Nuclear Information System (INIS)

Fuchs, Elina

2014-11-01

Mixing effects in the MSSM Higgs sector can give rise to a sizeable interference between the neutral Higgs bosons. On the other hand, factorising a more complicated process into production and decay parts by means of the narrow-width approximation (NWA) simplifies the calculation. The standard NWA, however, does not account for interference terms. Therefore, we introduce a generalisation of the NWA (gNWA) which allows for a consistent treatment of interference effects between nearly mass-degenerate particles. Furthermore, we apply the gNWA at the tree and 1-loop level to an example process where the neutral Higgs bosons h and H are produced in the decay of a heavy neutralino and subsequently decay into a fermion pair. The h-H propagator mixing is found to agree well with the approximation of Breit-Wigner propagators times finite wave-function normalisation factors, both leading to a significant interference contribution. The factorisation of the interference term based on on-shell matrix elements reproduces the full interference result within a precision of better than 1% for the considered process. The gNWA also enables the inclusion of contributions beyond the 1-loop order into the most precise prediction.

Effect of an extended Higgs sector on the electric dipole moment of a single quark in the Kobayashi-Maskawa model of CP violation

Escobar, C.O.; Pleites, V.

We argue that the existence of flavor-changing Higgs-boson couplings in an extended Higgs sector, respecting the experimental bounds on such processes, is sufficient to increase by some orders of magnitude the electric dipole moment of a single quark in the Kobayashi-Maskawa model of CP violation

Higgs-Palatini inflation and unitarity

International Nuclear Information System (INIS)

Bauer, Florian; Demir, Durmus A.

2011-01-01

In the Higgs inflation scenario the Higgs field is strongly coupled to the Ricci scalar in order to drive primordial inflation. However, in its original form in pure metric formulation of gravity, the ultraviolet (UV) cutoff of the Higgs interactions and the Hubble rate are of the same magnitude, and this makes the whole inflationary evolution dependent of the unknown UV completion of the Higgs sector. This problem, the unitarity violation, plagues the Higgs inflation scenario. In this Letter we show that, in the Palatini formulation of gravitation, Higgs inflation does not suffer from unitarity violation since the UV cutoff lies parametrically much higher than the Hubble rate so that unknown UV physics does not disrupt the inflationary dynamics. Higgs-Palatini inflation, as we call it, is, therefore, UV-safe, minimal and endowed with predictive power.

We study the general Zee model, which includes an extra Higgs scalar doublet and a new singly-charged scalar singlet. Neutrino masses are generated at one-loop level, and in order to describe leptonic mixing, both the Standard Model and the extra Higgs scalar doublets need to couple to leptons (in a type-III two-Higgs doublet model), which necessarily generates large lepton flavor violating signals, also in Higgs decays. Imposing all relevant phenomenological constraints and performing a full numerical scan of the parameter space, we find that both normal and inverted neutrino mass orderings can be fitted, although the latter is disfavored with respect to the former. In fact, inverted ordering can only be accommodated if θ{sub 23} turns out to be in the first octant. A branching ratio for h→τμ of up to 10{sup −2} is allowed, but it could be as low as 10{sup −6}. In addition, if future expected sensitivities of τ→μγ are achieved, normal ordering can be almost completely tested. Also, μe conversion is expected to probe large parts of the parameter space, excluding completely inverted ordering if no signal is observed. Furthermore, non-standard neutrino interactions are found to be smaller than 10{sup −6}, which is well below future experimental sensitivity. Finally, the results of our scan indicate that the masses of the additional scalars have to be below 2.5 TeV, and typically they are lower than that and therefore within the reach of the LHC and future colliders.

We evaluate weak mass mixing among the neutral heavy mesons with a bottom (Q = -1/3) or top (Q = +2/3) quark and CP-violation in the frame work of six quark (V - A) models. It is argued that bottom and top mesons may distinguish the Higgs exchange mechanism of CP-violation from a complex phase in the quark mass matrix, if bottom and top quark masses are sufficiently different. Estimates of weak mixing-and CP-violating effects for e + e - experiments at PETRA, PEP and CESR energies are presented. (orig.) [de

Interplay of Higgs phenomenology and new physics in supersymmetric theories

Supersymmetric (SUSY) theories such as the Minimal Supersymmetric Standard Model (MSSM) predict a new particle spectrum, including an extended Higgs sector, in order to address fundamental questions that remain unanswered with the results obtained at the Large Hadron Collider (LHC) so far. Despite an extensive programme to search for additional Higgs bosons at the LHC, no new Higgs-like particles have been observed beyond the discovered signal at 125 GeV. Such searches have not taken into account CP-violating effects in the Higgs sector, which are well-motivated in the light of the perceived baryon asymmetry in the universe, and which can induce significant deviations in the phenomenology of the Higgs bosons. The search for additional Higgs bosons should therefore account for the possibility that they may not necessarily be CP-eigenstates. In the most general case where the MSSM parameters can be complex, the three neutral Higgs bosons of the theory are the loop-corrected mass eigenstates {h_1,h_2,h_3}, which are admixtures of the tree-level CP-even and CP-odd Higgs states. This thesis focusses on the effects of complex parameters on the production cross sections of these Higgs bosons and the interference occurring between nearly mass-degenerate Higgs states. In the first part of this thesis, we discuss higher-order corrections in the Higgs sector which give rise to CP-violating mixing between the tree-level mass eigenstates, and present a computation of inclusive cross sections for the production of the CP-admixed Higgs bosons through gluon fusion and bottom-quark annihilation. The predictions for the gluon-fusion process are based on an explicit calculation of the leading-order cross section for the general case of arbitrary complex parameters, supplemented by various higher-order corrections. The cross sections for the bottom-quark annihilation process are treated with a simple re-weighting procedure. In the next part, we describe the implementation of our

Reconstructing neutrino properties from collider experiments in a Higgs triplet neutrino mass model

We extend the minimal supersymmetric standard model with bilinear R-parity violation to include a pair of Higgs triplet superfields. The neutral components of the Higgs triplets develop small vacuum expectation values (VEVs) quadratic in the bilinear R-parity breaking parameters. In this scheme the atmospheric neutrino mass scale arises from bilinear R-parity breaking while for reasonable values of parameters the solar neutrino mass scale is generated from the small Higgs triplet VEVs. We calculate neutrino masses and mixing angles in this model and show how the model can be tested at future colliders. The branching ratios of the doubly charged triplet decays are related to the solar neutrino angle via a simple formula

Neutral Supersymmetric Higgs Boson Searches at D0

Robinson, S.

2009-01-01

In some Supersymmetric extensions of the Standard Model, including the Minimal Supersymmetric Standard Model (MSSM), the coupling of Higgs bosons to b-quarks is enhanced. This enhancement makes the associated production of the Higgs with b-quarks an interesting search channel for the Higgs and Supersymmetry at D0. The identification of b-quarks, both online and offline, is essential to this search effort. This thesis describes the author's involvement in the development of both types of b-tagging and in the application of these techniques to the MSSM Higgs search. Work was carried out on the Level-3 trigger b-tagging algorithms. The impact parameter (IP) b-tagger was retuned and the effects of increased instantaneous luminosity on the tagger were studied. An extension of the IP-tagger to use the z-tracking information was developed. A new b-tagger using secondary vertices was developed and commissioned. A tool was developed to allow the use of large multi-run samples for trigger studies involving b-quarks. Offline, a neural network (NN) b-tagger was trained combining the existing offline lifetime based b-tagging tools. The efficiency and fake rate of the NN b-tagger were measured in data and MC. This b-tagger was internally reviewed and certified by the Collaboration and now provides the official b-tagging for all analyses using the Run IIa dataset at D0. A search was performed for neutral MSSM Higgs bosons decaying to a b(bar b) pair and produced in association with one or more b-quarks. Limits are set on the cross-section times the branching ratio for such a process. The limits were interpreted in various MSSM scenarios. This analysis uses the NN b-tagger and was the first to use this tool. The analysis also relies on triggers using the Level-3 IP b-tagging tool described previously. A likelihood discriminant was used to improve the analysis and a neural network was developed to cross-check this technique. The result of the analysis has been submitted to PRL and

CP violating mixings of toponium states

Loew, U.

1988-01-01

In the present thesis the possibility of an admixture χ of the 2 1 P 1 toponium state which has the CP quantum number -1 to the 2 3 S 1 toponium state with CP quantum number +1 is discussed. The value of χ was estimated in 3 different models of the electroweak interaction. In the standard model the lowest contribution to χ is of 6th order in the weak coupling g or of 4th order in g and of 2nd order in the strong coupling g S . The Feynman diagrams which contribute to χ contain 2 loops. According to a crude estimate of these diagrams it is expected that they yield a contribution smaller than 10 -10 . In the model with extended Higgs sector - for a top-quark mass of 45 GeV - a value of 7x10 -4 resulted for χ. For a top-quark mass of 100 GeV it is expected that χ is even of the order of magnitude of 10 -2 . The large contributions originate from CP violating coupling neutral Higgs particles. In the right-left symmetric model two contributions to χ were calculated. The first one results from the exchange of the right- and left-handed W bosons. For a mass m R =500 GeV this contribution lies at χ ≅ 10 -14 . The second contribution is again based on the exchange of two neutral CP violating coupling Higgs particles. It lies in the order of magnitude at 10 -8 . Possibilities were indicated to find the estimated admixture χ in an experiment. A correlation in the 3-gluon decay of toponium and the decay of toponium into exclusive decays was discussed. (orig./HSI) [de

Limits on the cross-section times branching fraction for neutral Higgs bosons, produced in $pp$ collisions at $\\sqrt{s} = 7$ TeV, and decaying to two tau leptons with pseudorapidities between 2.0 and 4.5, are presented. The result is based on a dataset, corresponding to an integrated luminosity of 1.0 $\\mathrm{fb}^{-1}$, collected with the LHCb detector. Candidates are identified by reconstructing final states with two muons, a muon and an electron, a muon and a hadron, or an electron and a hadron. A model independent upper limit at the 95% confidence level is set on a neutral Higgs boson cross-section times branching fraction. It varies from 8.6 pb for a Higgs boson mass of 90 GeV to 0.7 pb for a Higgs boson mass of 250 GeV, and is compared to the Standard Model expectation. An upper limit on $\\tan\\beta$ in the Minimal Supersymmetric Model is set in the $m_{h^0}^\\mathrm{max}$ scenario. It ranges from 34 for a CP-odd Higgs boson mass of 90 GeV to 70 for a pseudo-scalar Higgs boson mass of 140 GeV.

CP violation and the top quark

We consider signals of CP violation in semi-leptonic decay of the top quark. We show that the transverse polarization asymmetries of the τ-lepton in the decay t → brv is extremely sensitive CP violation. As an illustration we consider CP phases arising from the charged Higgs exchange in the Weinberg three Higgs doublet model. Qualitatively, the polarization asymmetries are enhanced over rate or energy asymmetries by a factor of O(m t /m r ) ∼ 100 with a corresponding increase in sensitivity to CP violating parameters. We also examine τ polarization in b decays via b → cvr and find that may also be very effective in constraining CP violating effects such as those that arise from an extended Higgs sector

Flavor physics and CP violation

We currently live in the age of the CKM paradigm. The 3 × 3 matrix that links (d , s , b) quarks to (u , c , t) in the charged current weak interaction, being complex and nominally with 18 parameters, can be accounted for by just 3 rotation angles and one CP violating (CPV) phase, with unitarity and the CKM phases triumphantly tested at the B factories. But the CKM picture is unsatisfactory and has too many parameters. The main aim of Flavor Physics and CP violation (FPCP) studies is the pursuit to uncover New Physics beyond the Standard Model (SM). Two highlights of LHC Run 1 period are the CPV phase ϕs of Bs mixing and Bs →μ+μ- decay, which were found to be again consistent with SM, though the saga is yet unfinished. We also saw the emergence of the P5‧ angular variable anomaly in B0 →K∗0μ+μ- decay and R K (∗) anomaly in B →K (∗)μ+μ- to B →K (∗)e+e- rate ratios, and the BaBar anomaly in B →D (∗) τν decays, which suggest possible New Physics in these flavor processes, pointing to extra Z‧, charged Higgs, or leptoquarks. Charmless hadronic, semileptonic, purely leptonic and radiative B decays continue to offer various further windows on New Physics. Away from B physics, the rare K → πνν decays and ε‧ / ε in the kaon sector, μ → e transitions, muon g - 2 and electric dipole moments of the neutron and electron, τ → μγ , μμμ , eee, and a few charm physics probes, offer broadband frontier windows on New Physics. Lastly, flavor changing neutral transitions involving the top quark t and the 125 GeV Higgs boson h, such as t → ch and h → μτ, offer a new window into FPCP, while a new Z‧ related or inspired by the P5‧ anomaly, could show up in analogous top quark processes, perhaps even link with low energy phenomena such as muon g - 2 or rare kaon processes. In particular, we advocate the potential new SM, the two Higgs doublet model without discrete symmetries to control flavor violation, as SM2. As we are

A phenomenological study on the production of Higgs bosons in the cSMCS model at the LHC

Directory of Open Access Journals (Sweden)

N. Darvishi

2017-10-01

Full Text Available In the present work, we intend to predict the production rates of the Higgs bosons in the simplest extension of the Standard Model (SM by a neutral complex singlet (cSMCS. This model has an additional source of CP violation and provides strong enough first-order electroweak phase transition to generate the baryon asymmetry of universe (BAU. The scalar spectrum of the cSMCS includes three neutral Higgs particles with the lightest one considered to be the 125 GeV Higgs boson found at LHC. The SM-like Higgs boson comes mostly from the SM-like SU(2 doublet, with a small correction from the singlet. To predict the production rates of the Higgs bosons, we use a conventional effective LO QCD framework and the unintegrated parton distribution functions (UPDF of Kimber–Martin–Ryskin (KMR. We first compute the SM Higgs production cross-section and compare the results to the existing theoretical calculations from different frameworks as well as the experimental data from the CMS and ATLAS collaborations. It is shown that our framework is capable of producing sound predictions for these high-energy QCD events in the SM. Afterwards we present our predictions for the Higgs boson production in the cSMCS.

B→τν: Opening up the charged Higgs parameter space with R-parity violation

International Nuclear Information System (INIS)

Bose, Roshni; Kundu, Anirban

2012-01-01

The theoretically clean channel B + →τ + ν shows a close to 3σ discrepancy between the Standard Model prediction and the data. This in turn puts a strong constraint on the parameter space of a two-Higgs doublet model, including R-parity conserving supersymmetry. The constraint is so strong that it almost smells of fine-tuning. We show how the parameter space opens up with the introduction of suitable R-parity violating interactions, and release the tension between data and theory.

The CP-violating 2HDM in light of a strong first order electroweak phase transition and implications for Higgs pair production

Basler, P.; Mühlleitner, M.; Wittbrodt, J.

2018-03-01

We investigate the strength of the electroweak phase transition (EWPT) within the CP-violating 2-Higgs-Doublet Model (C2HDM). The 2HDM is a simple and well-studied model, which can feature CP violation at tree level in its extended scalar sector. This makes it, in contrast to the Standard Model (SM), a promising candidate for explaining the baryon asymmetry of the universe through electroweak baryogenesis. We apply a renormalisation scheme which allows efficient scans of the C2HDM parameter space by using the loop-corrected masses and mixing matrix as input parameters. This procedure enables us to investigate the possibility of a strong first order EWPT required for baryogenesis and study its phenomenological implications for the LHC. Like in the CP-conserving (real) 2HDM (R2HDM) we find that a strong EWPT favours mass gaps between the non-SM-like Higgs bosons. These lead to prominent final states comprised of gauge+Higgs bosons or pairs of Higgs bosons. In contrast to the R2HDM, the CP-mixing of the C2HDM also favours approximately mass degenerate spectra with dominant decays into SM particles. The requirement of a strong EWPT further allows us to distinguish the C2HDM from the R2HDM using the signal strengths of the SM-like Higgs boson. We additionally find that a strong EWPT requires an enhancement of the SM-like trilinear Higgs coupling at next-to-leading order (NLO) by up to a factor of 2.4 compared to the NLO SM coupling, establishing another link between cosmology and collider phenomenology. We provide several C2HDM benchmark scenarios compatible with a strong EWPT and all experimental and theoretical constraints. We include the dominant branching ratios of the non-SM-like Higgs bosons as well as the Higgs pair production cross section of the SM-like Higgs boson for every benchmark point. The pair production cross sections can be substantially enhanced compared to the SM and could be observable at the high-luminosity LHC, allowing access to the trilinear

Focus Point Supersymmetry Proton Decay, Flavor and CP Violation, and the Higgs Boson Mass

Feng, J L; Feng, Jonathan L; Matchev, Konstantin T.

2001-01-01

In focus point supersymmetry, all squarks and sleptons, including those of the third generation, have multi-TeV masses without sacrificing naturalness. We examine the implications of this framework for low energy constraints and the light Higgs boson mass. Undesirable contributions to proton decay and electric dipole moments, generic in many supersymmetric models, are strongly suppressed. As a result, the prediction for alpha_s in simple grand unified theories is 3 to 5 standard deviations closer to the experimental value, and the allowed CP-violating phases are larger by one to two orders of magnitude. In addition, the very heavy top and bottom squarks of focus point supersymmetry naturally produce a Higgs boson mass at or above 115 GeV without requiring heavy gauginos. We conclude with an extended discussion of issues related to the definition of naturalness and comment on several other prescriptions given in the literature.

CP violation in top pair production at an e^+e^- collider

CERN Document Server

Chang, Darwin; Phillips, Ivan

1992-01-01

We investigate a possible CP violating effect in $e^+e^-$ annihilation into $t\\bar t$ top quark pairs. As an illustrative example, we assume the source of the CP nonconservation is in the Yukawa couplings of a neutral Higgs boson which contain both scalar and pseudoscalar pieces. One of the interesting observable effects is the difference in production rates between the two CP conjugate polarized $t\\bar t$ states.

Minkowski space structure of the Higgs potential in the two-Higgs-doublet model. II. Minima, symmetries, and topology

International Nuclear Information System (INIS)

Ivanov, I. P.

2008-01-01

We continue to explore the consequences of the recently discovered Minkowski space structure of the Higgs potential in the two-Higgs-doublet model. Here, we focus on the vacuum properties. The search for extrema of the Higgs potential is reformulated in terms of 3-quadrics in the 3+1-dimensional Minkowski space. We prove that 2HDM cannot have more than two local minima in the orbit space and that a twice-degenerate minimum can arise only via spontaneous violation of a discrete symmetry of the Higgs potential. Investigating topology of the 3-quadrics, we give concise criteria for existence of noncontractible paths in the Higgs orbit space. We also study explicit symmetries of the Higgs potential/Lagrangian and their spontaneous violation from a wider perspective than usual

This article reviews recent measurements of the properties of the standard model (SM) Higgs boson using data recorded with the CMS detector at the LHC: its mass, width and couplings to other SM particles. We also summarise highlights from searches for new physical phenomena in the Higgs sector as they are proposed in many extensions of the SM: flavour violating and invisible decay modes, resonances decaying into Higgs bosons and searches for additional Higgs bosons.

Neutral Higgs production at proton colliders in the CP-conserving NMSSM

Liebler, Stefan

2015-02-01

We discuss neutral Higgs boson production through gluon fusion and bottom-quark annihilation in the CP-conserving Z 3 -invariant Next-to-Minimal Supersymmetric Standard Model (NMSSM) at proton colliders. For gluon fusion we adapt known asymptotic expansions in supersymmetric particles for the inclusion of next-to-leading order contributions of squarks and gluinos from the Minimal Supersymmetric Standard Model (MSSM) and include electro-weak corrections involving light quarks. Together with the resummation of higher order sbottom contributions in the bottom-quark Yukawa coupling for both production processes we thus present accurate cross section predictions implemented in a new release of the code SusHi. We elaborate on the new features of an additional SU(2) L singlet in the production of CP-even and -odd Higgs bosons with respect to the MSSM and include a short discussion of theory uncertainties.

Search for a neutral Higgs boson

International Nuclear Information System (INIS)

Malmgren, T.G.M.

1997-04-01

The mass of the neutral Higgs boson cannot be predicted by models. Therefore, the particle is scanned for at different assumed masses. The search described here was done using data taken at the DELPHI detector in 1993. The Bjorken process was searched for where the decay of the Z 0* into two neutrinos was assumed. In order to reduce the background to a level where a discovery would be possible, an artificial feed-forward neural network was used. This led to a very good background rejection and high signal efficiency. An efficiency of around 30-50% was reached for a H 0 mass ranging from 35-60 GeV/c 2 leaving zero background events. One event was selected from the real data with a H 0 mass of 27.5(3.6) GeV/c 2 . These results were translated into a limit m H >58.3 GeV/c 2 at 95% confidence level

Charged tensor matter fields and Lorentz symmetry violation via spontaneous symmetry breaking

International Nuclear Information System (INIS)

Colatto, L.P.; Penna, A.L.A.; Santos, W.C.

2003-10-01

We consider a model with a charged vector field along with a Cremmer-Scherk-Kalb-Ramond (CSKR) matter field coupled to a U(1) gauge potential. We obtain a natural Lorentz symmetry violation due to the local U(1) spontaneous symmetry breaking mechanism triggered by the imaginary part of the vector matter. The choice of the unitary gauge leads to the decoupling of the gauge-Kr sector from the Higgs-Kr sector. The excitation spectrum is carefully analyzed and the physical modes are identified. We propose an identification of the neutral massive spin-1 Higgs-like field with the massive Z' boson of the so-called mirror matter models. (author)

Limits on neutral Higgs production in the forward region in pp collisions at $\\sqrt{s}$=7 TeV

2013-01-01

Limits on the cross-section times branching fraction for Higgs particles, produced in pp collisions at $\\sqrt{s}$ = 7 TeV, and decaying to two taus with pseudorapidities between 2 and 4.5, are presented. The result is based on a dataset of 1.0 fb$^{-1}$ collected by the LHCb detector. Model independent upper limits on neutral Higgs cross-section times branching fraction are set and are compared to the SM Higgs expectation. Model dependent MSSM upper limits on tan(beta) are also set.

CP violation in atoms

Barr, S.M.

1992-01-01

Electric dipole moments of large atoms are an excellent tool to search for CP violation beyond the Standard Model. These tell us about the electron EDM but also about CP-violating electron-nucleon dimension-6 operators that arise from Higgs-exchange. Rapid strides are being made in searches for atomic EDMs. Limits on the electron EDM approaching the values which would be expected from Higgs-exchange mediated CP violation have been achieved. It is pointed out that in this same kind of model if tan β is large the effects in atoms of the dimension-6 e - n operators may outweigh the effect of the electron EDM. (author) 21 refs

CP-violation in the ZZZ and ZWW vertices at e"+e"− colliders in Two-Higgs-Doublet Models

International Nuclear Information System (INIS)

Grzadkowski, B.; Ogreid, O.M.; Osland, P.

2016-01-01

We discuss possibilities of measuring CP violation in the Two-Higgs-Doublet Model by studying effects of one-loop generated ZZZ and ZWW vertices. We discuss a set of CP-sensitive asymmetries for ZZ and W"+W"− production at linear e"+e"−-colliders, that directly depends on the weak-basis invariant ℑJ_2 that parametrises the strength of CP violation. Given the restrictions on this model that follow from the LHC measurements, the predicted effects are small. Pursuing such measurements is however very important, as an observed signal might point to a richer scalar sector.

Experimental searches for CP and CPT symmetries violation in the neutral kaons system

International Nuclear Information System (INIS)

Debu, P.

1996-01-01

The aim of this lecture is to give an overview of the experiments devoted to the study and research of CP, T and CPT symmetries invariance violations in the system of neutral K mesons. The discovery of K mesons has provided crucial informations for the elaboration of the standard model. However, the observation of CP violation has remained confined to the K system. The origin of the observed CP violation remains hypothetic. Its origin could be a complex phase in the mixing matrix of quarks. In the standard model of electroweak interactions, several evidences of the CP violation exist: the observed K neutral mesons (K L and K S ) are not proper states of CP and are due to CP violation in the K 0 - anti-K 0 mixture. On the other hand, the model predicts also a CP violation in decay amplitudes, named direct CP violation. Important experiments have been carried out for its demonstration. The K system is also the most precise test for CPT invariance. A description of the experiments in progress developed to improve the precision of these tests is given. The plan of the lecture is the following: after a recall of K 0 - anti-K 0 phenomenology, some important steps in the CP violation study are described. Then, the regeneration phenomenon is briefly described and two of the most recent measurements of the direct CP violation parameter are analysed. Finally, the CPT invariance tests are described with their parameters and the measurements in progress. A review of the principal results is given in conclusion with their improvements expected in a near future. (J.S.). 71 refs., 4 figs., 4 tabs

Bounds from B 0 - anti B 0 mixing on charged-Higgs-boson masses and couplings in two-Higgs-doublet models are presented. These bounds are comparable to those obtained, with additional assumptions, from the neutral-K-system. The effects of the neutral Higgs bosons of these models on the spectrum and wave function of toponium are discussed. These effects could, in the future, lead to limits on, or the discovery of, these Higgs bosons. 8 refs., 3 figs

Higgs-boson and Z-boson flavor-changing neutral-current decays correlated with B-meson decays in the littlest Higgs model with T parity

International Nuclear Information System (INIS)

Han Xiaofang; Wang Lei; Yang Jinmin

2008-01-01

In the littlest Higgs model with T-parity new flavor-changing interactions between mirror fermions and the standard model (SM) fermions can induce various flavor-changing neutral-current decays for B-mesons, the Z-boson, and the Higgs boson. Since all these decays induced in the littlest Higgs with T-parity model are correlated, in this work we perform a collective study for these decays, namely, the Z-boson decay Z→bs, the Higgs-boson decay h→bs, and the B-meson decays B→X s γ, B s →μ + μ - , and B→X s μ + μ - . We find that under the current experimental constraints from the B-decays, the branching ratios of both Z→bs and h→bs can still deviate from the SM predictions significantly. In the parameter space allowed by the B-decays, the branching ratio of Z→bs can be enhanced up to 10 -7 (about one order above the SM prediction) while h→bs can be much suppressed relative to the SM prediction (about one order below the SM prediction).

B decays and models for CP violation

The decay modes B to π π,υK S , K - D, πK and ηK are promising channels to study the unitarity triangle of the CP violating Cabibbo-Kobayashi-Maskawa (CKM) matrix. The consequences of these measurements in the Weinberg model are discussed. It is shown that measurements of CP violation in B decay can be used to distinguish Standard Model from Weinberg model and that the following different mechanisms for CP violation can be distinguished: 1) CP is violated in the CKM sector only; 2) CP is violated spontaneously in the Higgs sector only; and 3) CP is violated in both the CKM and Higgs sectors. 27 refs., 4 figs

Search for lepton flavour violating decays of the Higgs boson to $\\mu\\tau$ and e$\\tau$ in proton-proton collisions at $\\sqrt{s}=$ 13 TeV

2017-12-19

A search for lepton flavour violating decays of the Higgs boson in the $\\mu\\tau$ and e$\\tau$ decay modes is presented. The search is based on a data set corresponding to an integrated luminosity of 35.9 fb$^{-1}$ of proton-proton collisions collected with the CMS detector in 2016, at a centre-of-mass energy of 13 TeV. No significant excess over the standard model expectation is observed. The observed (expected) upper limits on the lepton flavour violating branching fractions of the Higgs boson are $\\mathcal{B}$(H$\\to\\mu\\tau$) < 0.25% (0.25%) and $\\mathcal{B}$(H$\\to$e$\\tau$) < 0.61% (0.37%), at 95% confidence level. These results are used to derive upper limits on the off-diagonal $\\mu\\tau$ and e$\\tau$ Yukawa couplings $\\sqrt{|{Y_{\\mu\\tau}}|^{2}+|{Y_{\\tau\\mu}}|^{2}}<1.43\\times 10^{-3}$ and $\\sqrt{|{Y_{\\mathrm{e}\\tau}}|^{2}+|{Y_{\\tau\\mathrm{e}}}|^{2}}<2.26\\times 10^{-3}$ at 95% confidence level. The limits on the lepton flavour violating branching fractions of the Higgs boson and on the associated Yukawa couplings are the most stringent to date.

I show that using the same set of measurements, the following different mechanisms for CP violation can be distinguished: (1) CP is violated in the CKM sector only; (2) CP is violated spontaneously in the Higgs sector only; and (3) CP is violated in both the CKM and Higgs sectors. copyright 1996 The American Physical Society

Higgs boson masses in a non-minimal supersymmetric model

Tiesi, Alessandro

2002-01-01

A study of the neutral Higgs spectrum in a general Z 3 -breaking Next to Minimal Supersymmetric Standard Model (NMSSM) is reported in several significant contexts. Particular attention has been devoted to the upper bound on lightest Higgs boson. In the CP-conserving case we show that the extra terms involved in the general Z 3 -breaking superpotential do not affect the upper bound which remains unchanged: it is ∼ 136 GeV when tan β = 2.7. The Spontaneous CP Violation scenario in the Z 3 -breaking NMSSM can occur at tree-level. When the phases of the fields are small the spectrum shows the lightest Higgs particle to be an almost singlet CP-odd. The second lightest particle, a doublet almost-CP-even state, still manifests the upper bound of the CP-conserving case. When the CP-violating phases are large the lightest particle is a doublet with no definite CP parity and its mass shows the usual upper bound at ∼ 136 GeV. The large number of parameters involved in the effective potential can be significantly reduced in the Infrared Quasi Fixed Point (IRQFP) resulting after solving the Renormalization Group (RG) equations assuming universality for the soft SUSY breaking masses. In the Z 3 -breaking NMSSM, unlike the Z 3 -conserving NMSSM, it is possible to find a Higgs spectrum which is still compatible with both experiment and universality at the unification scale. Because in the IRQFP regime tan β ∼ 1.8 and the stop mixing parameter is reduced then the upper bound on the lightest Higgs boson turns out to be ∼ 121 GeV. This result is compatible with experimental data coming from LEPII and might be one of the next predictions to be tested at hadron collider experiments. (author)

Search for the neutral MSSM Higgs bosons in the ditau decay channels at CDF Run II

2008-04-01

This thesis presents the results on a search for the neutral MSSM Higgs bosons decaying to tau pairs, with least one of these taus decays leptonically. The search was performed with a sample of 1.8 fb^-1 of proton-antiproton collisions at √s = 1.96 TeV provided by the Tevatron and collected by CDF Run II. No significant excess over the Standard Model prediction was found and a 95% confidence level exclusion limit have been set on the cross section times branching ratio as a function of the Higgs boson mass. This limit has been translated into the MSSM Higgs sector parameter plane, tanβ vs. M_A, for the four different benchmark scenarios.

Status of the charged Higgs boson in two Higgs doublet models

The existence of charged Higgs boson(s) is inevitable in models with two (or more) Higgs doublets. Hence, their discovery would constitute unambiguous evidence for new physics beyond the Standard Model (SM). Taking into account all relevant results from direct charged and neutral Higgs boson searches at LEP and the LHC, as well as the most recent constraints from flavour physics, we present a detailed analysis of the current phenomenological status of the charged Higgs sector in a variety of well-motivated two Higgs doublet models (2HDMs). We find that charged Higgs bosons as light as 75 GeV can still be compatible with the combined data, although this implies severely suppressed charged Higgs couplings to all fermions. In more popular models, e.g. the 2HDM of Type II, we find that flavour physics observables impose a combined lower limit on the charged Higgs mass of M_{H^± } ≳ 600 GeV - independent of tan β - which increases to M_{H^± } ≳ 650 GeV for tan β < 1. We furthermore find that in certain scenarios, the signature of a charged Higgs boson decaying into a lighter neutral Higgs boson and a W boson provides a promising experimental avenue that would greatly complement the existing LHC search programme for charged Higgs boson(s).

This dissertation presents a measurement of time-dependent CP-violating asymmetries in neutral B meson decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at the Stanford Linear Accelerator Center. The data sample consists of about 88 million {Upsilon}(4S) {yields} B{bar B} decays collected between 1999 and 2002. We study events in which one neutral B meson decay to the CP-eigenstates J/{psi} K{sub S}{sup 0}, {psi}(2S)K{sub S}{sup 0}, {chi}{sub c1}K{sub S}{sup 0}, and {eta}{sub c}K{sub S}{sup 0}, or to flavor-eigenstates involving D{sup (*)}{pi}/{rho}/a{sub 1} and J/{psi}K*{sup 0}(K*{sup 0} {yields} K{sup +} {pi}{sup -}), is fully reconstructed. The flavor of the other neutral B meson is tagged at the time of its decay, mainly using the charge of identified leptons and kaons. The proper time elapsed between the meson decays is determined by measuring the distance between the decay vertices. The amplitude of the CP-violating asymmetry, which in the Standard Model is proportional to sin2{beta}, is determined from a simultaneous maximum-likelihood fit to the time-difference distribution of the flavor- and CP-eigenstate samples. We measure sin2{beta} = 0.755 {+-} 0.074 (stat) {+-} 0.030 (syst).

A search for a Higgs boson with suppressed couplings to fermions, hf, assumed to be the neutral, lower-mass partner of the Higgs boson discovered at the Large Hadron Collider, is reported. Such a Higgs boson could exist in extensions of the standard model with two Higgs doublets, and could be produced via p p ¯→H±hf→W*hfhf→4 γ +X , where H± is a charged Higgs boson. This analysis uses all events with at least three photons in the final state from proton-antiproton collisions at a center-of-mass energy of 1.96 TeV collected by the Collider Detector at Fermilab, corresponding to an integrated luminosity of 9.2 fb-1. No evidence of a signal is observed in the data. Values of Higgs-boson masses between 10 and 100 GeV /c2 are excluded at 95% Bayesian credibility.

We point out that the stringent lower bounds on the masses of additional electrically neutral and charged Higgs bosons crucially depend on the flavour structure of their Yukawa interactions. We show that these bounds can easily be evaded by the introduction of flavour-changing neutral currents in the Higgs sector. As an illustration, we study the phenomenology of a two Higgs doublet model with a Yukawa texture singling out the third family of quarks and leptons. We combine constraints from low-energy flavour physics measurements, LHC measurements of the 125 GeV Higgs boson rates, and LHC searches for new heavy Higgs bosons. We propose novel LHC searches that could be performed in the coming years to unravel the existence of these new Higgs bosons.

Direct searches for lepton flavour violation in decays of the Higgs and $Z$ bosons with the ATLAS detector at the LHC are presented. The following three decays are considered: $H\\to e\\tau$, $H\\to\\mu\\tau$, and $Z\\to\\mu\\tau$. The searches are based on the data sample of proton--proton collisions collected by the ATLAS detector corresponding to an integrated luminosity of 20.3 fb$^{-1}$ at a centre-of-mass energy of $\\sqrt{s} = 8$ TeV. No significant excess is observed, and upper limits on the lepton-flavour-violating branching ratios are set at the 95% confidence level: Br$(H\\to e\\tau) <$ 1.04%, Br$(H\\to\\mu\\tau) <$ 1.43%, and Br$(Z\\to\\mu\\tau) <$ 1.69 $\\times$ 10$^{-5}$.

Motivated by the naturalness and neutrino mass generation, we study a bilinear R-parity violating supersymmetric scenario with a light Higgsino-like lightest supersymmetric particle (LSP). We observe that the LSP can have substantial decay branching ratio to νh in a large part of the parameter space, and thus study the pair production of electroweakinos followed by the decays χ̃{sub 1}{sup ±}→χ̃{sub 1}{sup 0}W{sup ±(∗)} and χ̃{sub 1}{sup 0}→νh. This leads to an interesting signature of Higgs boson pair production associated with significantly large missing transverse energy which is grossly distinct from the di-Higgs production in the Standard Model. We investigate the perspective of probing such signatures by performing a detector level simulation using a toy calorimeter of both the signal and corresponding backgrounds for the high-luminosity high energy phase of the Large Hadron Collider (LHC). We also advocate some observables based on kinematical features to provide an excellent handle to suppress the backgrounds.

Search for neutral Higgs bosons decaying to tau pairs at the CMS experiment

The thesis describes a study of the tau-pair final state in the semi-leptonic decay mode into muon and hadrons using proton-proton collisions data at a center-of-mass energy of 7 TeV using the CMS detector at the CERN Large Hadron Collider. The performance of tau-lepton reconstruction and identification algorithm is studied using a data sample of proton-proton collisions at √ = 7 TeV, corresponding to an integrated luminosity of 36 pb -1 . The tau leptons that decay into one charged hadron with or without the association of neutral hadrons is reconstructed using Particle-Flow object reconstruction technique with a novel tau identification algorithm called the Hadron Plus Strips (HPS) algorithm in the CMS tracker and electromagnetic calorimeter. The reconstruction efficiency of the algorithm is measured using τ leptons produced in Z-boson decays. The hadronically decaying tau lepton mis-identification rate for jets produced in association with a W boson is also determined. The first measurement of inclusive Z →ττ production in pp collisions at the LHC is presented in muon + hadrons final state using a data sample of 36 pb -1 . The measured cross-section is in good agreement with the next-to-next-to-leading order (NNLO) QCD prediction. After establishing the Z boson in di-tau decay mode, an inclusive search for neutral minimal supersymmetric standard model (MSSM) Higgs bosons in pp collisions is performed at a center-of-mass energy of 7 TeV. The results are based on a data sample corresponding to an integrated luminosity of 36 pb -1 and 4.6 fb -1 recorded by the CMS experiment in the year 2010 and 2011 respectively. The search uses decays of the Higgs bosons to tau pairs. No excess is observed in the tau-pair invariant-mass spectrum. The resulting upper limits on the Higgs boson production cross-section times the branching fraction to tau pairs, as a function of the pseudoscalar Higgs boson mass, yield stringent bounds in the MSSM parameter space.

AUTHOR|(INSPIRE)INSPIRE-00233070

The search for additional heavy neutral Higgs bosons predicted in Minimal Supersymmetric Extensions of the Standard Model is presented, using the direct decay channel into two tau leptons which themselves decay hadronically. The study is based on proton-proton collisions recorded in 2011 at a center-of-mass energy of 7 TeV with the ATLAS detector at the Large Hadron Collider at CERN. With a sample size corresponding to an integrated luminosity of $4.5\\,\\text{fb}^{−1}$, no significant excess above the expected Standard Model background prediction is observed and $\\text{CL}_\\text{S}$ exclusion limits at a 95% confidence level are evaluated for values of the CP-odd Higgs boson mass mA between 140 GeV to 800 GeV within the context of the $m_\\text{h}^{\\text{max}}$ and $m^{\\text{mod}\\pm}_\\text{h}$ benchmark scenarios. The results are combined with searches for neutral Higgs h bosons performed using proton-proton collisions at a center-of-mass energy of 8 TeV recorded with the ATLAS detector in 2012, with a corres...

There are many possibilities for new physics beyond the Standard Model that feature non-standard Higgs sectors. These may introduce new sources of CP violation, and there may be mixing between multiple Higgs bosons or other new scalar bosons. Alternatively, the Higgs may be a composite state, or there may even be no Higgs at all. These non-standard Higgs scenarios have important implications for collider physics as well as for cosmology, and understanding their phenomenology is essential for a full comprehension of electroweak symmetry breaking. This report discusses the most relevant theories which go beyond the Standard Model and its minimal, CP-conserving supersymmetric extension: two-Higgs-doublet models and minimal supersymmetric models with CP violation, supersymmetric models with an extra singlet, models with extra gauge groups or Higgs triplets, Little Higgs models, models in extra dimensions, and models with technicolour or other new strong dynamics. For each of these scenarios, this report presents ...

While the Higgs particle of the Standard Models is a Cp-even scalar particle, extended models may contain Higgs particles that are odd under CP, and also models invoking Higgs-like particles which are not eigenstates of CP may be considered. In the context of Higgs production via the Bjorken process and Higgs decay to tour fermions distributions that are sensitive to the CP parity are discussed. The author also discuss observables which may demonstrate presence of CP violation and identify a phase shift {delta} which is a measure of the strength of CP violation in the Higgs-vector-vector coupling, and which can be measured directly in the relevant distribution. In the case of Higgs production via the Bjorken process at a future e{sup +}e{sup -}collider, Monte Carlo data on the expected efficiency is presented, and it is concluded that it is relatively easy to determine whether the produced particle is even or odd under CP. However, observation of any CP violation would require a very large amount of data. It is argued that the analogous prospects at LEP2 or at a future hadron collider like the LHC seem to be less promising. 63 refs.

Light neutral C P -even Higgs boson within the next-to-minimal supersymmetric standard model at the Large Hadron Electron Collider

We analyze the prospects of observing the light charge parity (C P )-even neutral Higgs bosons (h1) in their decays into b b ¯ quarks, in the neutral and charged current production processes e h1q and ν h1q at the upcoming Large Hadron Electron Collider (LHeC), with √{s }≈1.296 TeV . Assuming that the intermediate Higgs boson (h2 ) is Standard Model (SM)-like, we study the Higgs production within the framework of next-to-minimal supersymmetric Standard Model (NMSSM). We consider the constraints from dark-matter, sparticle masses, and the Higgs boson data. The signal in our analysis can be classified as three jets, with electron (missing energy) coming from the neutral (charged) current interaction. We demand that the number of b -tagged jets in the central rapidity region be greater or equal to two. The remaining jet is tagged in the forward regions. With this forward jet and two b -tagged jets in the central region, we reconstructed three jets invariant masses. Applying some lower limits on these invariant masses turns out to be an essential criterion to enhance the signal-to-background rates, with slightly different sets of kinematical selections in the two different channels. We consider almost all reducible and irreducible SM background processes. We find that the non-SM like Higgs boson, h1, would be accessible in some of the NMSSM benchmark points, at approximately the 0.4 σ (2.5 σ ) level in the e +3 j channel up to Higgs boson masses of 75 GeV, and in the ET +3 j channel could be discovered with the 1.7 σ (2.4 σ ) level up to Higgs boson masses of 88 GeV with 100 fb-1 of data in a simple cut-based (with optimization) selection. With ten times more data accumulation at the end of the LHeC run, and using optimization, one can have 5 σ discovery in the electron (missing energy) channel up to 85 (more than 90) GeV.

Exploring CP Violation in the MSSM

Arbey, A.; Godbole, R.M.; Mahmoudi, F.

We explore the prospects for observing CP violation in the minimal supersymmetric extension of the Standard Model (MSSM) with six CP-violating parameters, three gaugino mass phases and three phases in trilinear soft supersymmetry-breaking parameters, using the CPsuperH code combined with a geometric approach to maximize CP-violating observables subject to the experimental upper bounds on electric dipole moments. We also implement CP-conserving constraints from Higgs physics, flavour physics and the upper limits on the cosmological dark matter density and spin-independent scattering. We study possible values of observables within the constrained MSSM (CMSSM), the non-universal Higgs model (NUHM), the CPX scenario and a variant of the phenomenological MSSM (pMSSM). We find values of the CP-violating asymmetry A_CP in b -> s gamma decay that may be as large as 3%, so future measurements of A_CP may provide independent information about CP violation in the MSSM. We find that CP-violating MSSM contributions to the...

Better Higgs-C P tests through information geometry

Measuring the C P symmetry in the Higgs sector is one of the key tasks of the LHC and a crucial ingredient for precision studies, for example in the language of effective Lagrangians. We systematically analyze which LHC signatures offer dedicated C P measurements in the Higgs-gauge sector and discuss the nature of the information they provide. Based on the Fisher information measure, we compare the maximal reach for C P -violating effects in weak boson fusion, associated Z H production, and Higgs decays into four leptons. We find a subtle balance between more theory-independent approaches and more powerful analysis channels, indicating that rigorous evidence for C P violation in the Higgs-gauge sector will likely require a multistep process.

Bs0–B-bars0 mixing within minimal flavor-violating two-Higgs-doublet models

Chang, Qin; Li, Pei-Fu; Li, Xin-Qiang

2015-01-01

In the “Higgs basis” for a generic 2HDM, only one scalar doublet gets a nonzero vacuum expectation value and, under the criterion of minimal flavor violation, the other one is fixed to be either color-singlet or color-octet, which are named as the type-III and type-C models, respectively. In this paper, the charged-Higgs effects of these two models on B s 0 –B -bar s 0 mixing are studied. First of all, we perform a complete one-loop computation of the electro-weak corrections to the amplitudes of B s 0 –B -bar s 0 mixing. Together with the up-to-date experimental measurements, a detailed phenomenological analysis is then performed in the cases of both real and complex Yukawa couplings of charged scalars to quarks. The spaces of model parameters allowed by the current experimental data on B s 0 –B -bar s 0 mixing are obtained and the differences between type-III and type-C models are investigated, which is helpful to distinguish between these two models

A model for the origin and mechanisms of CP violation

International Nuclear Information System (INIS)

Wu, Y.

1995-01-01

In this talk I will show that the two-Higgs doublet model with vacuum CP violation and approximate global U(1) family symmetries may provide one of the simplest and attractive models for understanding the origin and mechanisms of CP violation. It is shown that the mechanism of spontaneous symmetry breaking provides not only a mechanism for generating masses of the bosons and fermions, but also a mechanism for creating CP-phases of the bosons and fermions, so that CP violation occurs, after spontaneous symmetry breaking, in all possible ways from a single CP phase of the vacuum and is generally classified into four types of CP-violating mechanism. A new type of CP-violating mechanism in the charged Higgs boson interactions of the fermions is emphasized and can provide a consistent description for both established and reported CP-, P-, and T-violating phenomena. Of particular importance is the new source of CP violation for charged Higgs boson interactions that lead to the value of ε'/ε as large as 10 -3 independent of the CKM phase. copyright 1995 American Institute of Physics

B-tagging and the search for neutral supersymmetric Higgs bosons at D0

2006-01-01

A search for neutral supersymmetric Higgs bosons and work relating to the improvement of the b-tagging and trigger capabilities at the D0 detector during Run II of the Fermilab Tevatron collider is presented. The search for evidence of the Higgs sector in the Standard Model (SM) and supersymmetric extensions of the SM are a high priority for the D0 collaboration, and b-tagging and good triggers are a vital component of these searches. The development and commissioning of the first triggers at D0 which use b-tagging is outlined, along with the development of a new secondary vertex b-tagging tool for use in the Level 3 trigger. Upgrades to the Level 3 trigger hit finding code, which have led to significant improvements in the quality and efficiency of the tracking code, and by extension the b-tagging tools, are also presented. An offline Neural Network (NN) b-tagging tool was developed, trained on Monte Carlo and extensively tested and measured on data. The new b-tagging tool significantly improves the b-tagging performance at D0, for a fixed fake rate relative improvements in signal efficiency range from ∼ 40% to ∼ 15%. Fake rates, for a fixed signal efficiency, are typically reduced to between a quarter and a third of their value. Finally, three versions of the search for neutral supersymmetric Higgs bosons are presented. The latest version of the analysis makes use of almost 1 fb -1 of data, the new NN b-tagger and the new b-tagging triggers, and has set one of the world's best limits on the supersymmetric parameter tanβ in the mass range 90 to 150 GeV

A new tool for the study of the CP-violating NMSSM

International Nuclear Information System (INIS)

Domingo, Florian

2015-03-01

Supersymmetric extensions of the Standard Model open up the possibility for new types of CP-violation. We consider the case of the Next-to-Minimal Supersymmetric Standard Model where, beyond the phases from the soft lagrangian, CP-violation could enter the Higgs sector directly at tree-level through complex parameters in the superpotential. We develop a series of Fortran subroutines, cast within the public tool NMSSMTools and allowing for a phenomenological analysis of the CP-violating NMSSM. This new tool performs the computation of the masses and couplings of the various new physics states in this model: leading corrections to the sparticle masses are included; the precision for the Higgs masses and couplings reaches the full one-loop and leading two-loop order. The two-body Higgs and top decays are also attended. We use the public tools HiggsBounds and HiggsSignals to test the Higgs sector. Additional subroutines check the viability of the sparticle spectrum in view of LEP-limits and constrain the phases of the model via a confrontation to the experimentally measured Electric Dipole Moments. These tools will be made publicly available in the near future. In this paper, we detail the workings of our code and illustrate its use via a comparison with existing results. We also consider some consequences of CP-violation for the NMSSM Higgs sector.

QCD corrections to decay distributions of neutral Higgs bosons with (in)definite CP parity

We compute the order α s QCD corrections to the density matrix for the decay of a neutral Higgs boson var-phi with (in)definite CP parity into a quark-antiquark pair and the QED corrections for the decay into a pair of charged leptons. We classify and calculate single spin asymmetries and spin-spin correlations which are generated by the scalar and pseudoscalar Yukawa couplings. These spin effects can be traced in var-phi →τ - τ + and, for heavy Higgs bosons, in var-phi →t bar t. We also calculate resulting correlations among the final states and estimate, for the respective decay modes, the number of events needed to measure the Yukawa couplings with these correlations at the 3σ level. copyright 1997 The American Physical Society

Model for particle masses, flavor mixing, and CP violation, based on spontaneously broken discrete chiral symmetry as the origin of families

International Nuclear Information System (INIS)

Adler, S.L.

1999-01-01

We construct extensions of the standard model based on the hypothesis that Higgs bosons also exhibit a family structure and that the flavor weak eigenstates in the three families are distinguished by a discrete Z 6 chiral symmetry that is spontaneously broken by the Higgs sector. We study in detail at the tree level models with three Higgs doublets and with six Higgs doublets comprising two weakly coupled sets of three. In a leading approximation of S 3 cyclic permutation symmetry the three-Higgs-doublet model gives a open-quotes democraticclose quotes mass matrix of rank 1, while the six-Higgs-doublet model gives either a rank-1 mass matrix or, in the case when it spontaneously violates CP, a rank-2 mass matrix corresponding to nonzero second family masses. In both models, the CKM matrix is exactly unity in the leading approximation. Allowing small explicit violations of cyclic permutation symmetry generates small first family masses in the six-Higgs-doublet model, and first and second family masses in the three-Higgs-doublet model, and gives a nontrivial CKM matrix in which the mixings of the first and second family quarks are naturally larger than mixings involving the third family. Complete numerical fits are given for both models, flavor-changing neutral current constraints are discussed in detail, and the issues of unification of couplings and neutrino masses are addressed. On a technical level, our analysis uses the theory of circulant and retrocirculant matrices, the relevant parts of which are reviewed. copyright 1998 The American Physical Society

A search for neutral minimal supersymmetric standard model (MSSM) Higgs bosons in pp collisions at the LHC at a center-of-mass energy of 7 TeV is presented. The results are based on a data sample corresponding to an integrated luminosity of 36  pb(-1) recorded by the CMS experiment. The search uses decays of the Higgs bosons to tau pairs. No excess is observed in the tau-pair invariant-mass spectrum. The resulting upper limits on the Higgs boson production cross section times branching fraction to tau pairs, as a function of the pseudoscalar Higgs boson mass, yield stringent new bounds in the MSSM parameter space.

A search for neutral MSSM Higgs bosons in pp collisions at the LHC at a center-of-mass energy of 7 TeV is presented. The results are based on a data sample corresponding to an integrated luminosity of 36 inverse picobarns recorded by the CMS experiment. The search uses decays of the Higgs bosons to tau pairs. No excess is observed in the tau-pair invariant-mass spectrum. The resulting upper limits on the Higgs boson production cross section times branching fraction to tau pairs, as a function of the pseudoscalar Higgs boson mass, yield stringent new bounds in the MSSM parameter space.

CP Studies and Non-Standard Higgs Physics

DEFF Research Database (Denmark)

Kraml, S.; Accomando, E.; G. Akeroyd, A.

2006-01-01

There are many possibilities for new physics beyond the Standard Model that feature non-standard Higgs sectors. These may introduce new sources of CP violation, and there may be mixing between multiple Higgs bosons or other new scalar bosons. Alternatively, the Higgs may be a composite state......, or there may even be no Higgs at all. These non-standard Higgs scenarios have important implications for collider physics as well as for cosmology, and understanding their phenomenology is essential for a full comprehension of electroweak symmetry breaking. This report discusses the most relevant theories...

New Physics and novel Higgs signals

International Nuclear Information System (INIS)

Diaz-Cruz, J. Lorenzo

2003-01-01

We review some of the results of our recent work dealing with the novel type of Higgs signals that arise when one considers extensions of the standard model. We discuss first possible deviations on the Higgs couplings due to heavy particles, in the context of the MSSM and with large extra-dimensions. Then, we present several models where it is possible to induce flavor violating Higgs couplings, and probe them at future hadron colliders through the LFV Higgs decay h → τμ or with rare top decays

Maxwell-Higgs vortices with internal structure

Science.gov (United States)

Bazeia, D.; Marques, M. A.; Menezes, R.

2018-05-01

Vortices are considered in relativistic Maxwell-Higgs systems in interaction with a neutral scalar field. The gauge field interacts with the neutral field via the presence of generalized permeability, and the charged and neutral scalar fields interact in a way dictated by the presence of first order differential equations that solve the equations of motion. The neutral field may be seen as the source field of the vortex, and we study some possibilities, which modify the standard Maxwell-Higgs solution and include internal structure to the vortex.

Independent search for neutral Higgs boson flavour with the ALEPH detector at LEP2

International Nuclear Information System (INIS)

Pascolo, J.M.

2001-01-01

A flavour independent search for the neutral Higgs boson is performed in the four jets channel, e + e - → h(hadrons)Z(qq-bar), in the channel with missing energy, e + e - → h(hadrons)Z(νν-bar) and in the leptonic channel e + e - → h(hadrons)Z(e + e - ,μ + μ - ). The analysed data have been collected by the ALEPH detector at LEP during the years 1998, 1999 and 2000, at center of mass energies from 189 to 210 GeV. The selections in four jets and missing energy channels are based on the artificial neural networks multivariate method. This allows the non-linear combining of the signal information. In order to obtain a selection independent of the flavour of the Higgs boson decay products, this information is brought through purely kinematic and topologic variables. The selection in the leptonic channel is performed by a set of cuts that benefit from the very good electron and muon identification. No evidence of signal has been seen in the data collected by ALEPH up to 189 GeV. This allows us to restrict the allowed values of the mass, cross section and branching ratio of the Higgs boson. The result is expressed by a excluded region at 95% of confidence level in a two-dimension space. With this, it is possible to verify if a particular model is excluded or not by the experiment. This result is interpreted in the Standard Model and the MSSM. In the Standard Model, a lower limit is derived on the Higgs boson mass, M(Higgs) > 109.5 GeV/c 2 , with a 95% of confidence level.

Higgs bosons and sleptons in an alternative left-right model

International Nuclear Information System (INIS)

Roszkowski, L.

1990-01-01

The phenomenological structure of the combined Higgs-boson--slepton sector of the alternative left-right-supersymmetric model introduced by Ma is explored. Constraints upon and relations between Higgs-boson and slepton masses are derived and a tightly constrained mass spectrum is found. In general, one neutral Higgs boson is never heavier than 98 GeV, one neutral Higgs boson is always nearly degenerate in mass with the extra neutral gauge boson Z 2 0 , and the charged Higgs boson can in principle be as light as 22 GeV. Further constraints require large ratios of Higgs vacuum expectation values, strongly favor the W R mass above ∼423 GeV, predict one Higgs-boson mass to be always very close to 98 GeV, and masses of the other Higgs bosons and the sleptons to be bounded from above and preferably not much above the Z mass. In addition, the possibility of detecting light Higgs bosons at CERN LEP and the SLAC Linear Collider is briefly discussed

Higgs portal interactions provide a simple mechanism for addressing two open problems in cosmology: dark matter and the baryon asymmetry. In the latter instance, Higgs portal interactions may contain the ingredients for a strong first-order electroweak phase transition as well as new CP-violating interactions as needed for electroweak baryogenesis. These interactions may also allow for a viable dark matter candidate. We survey the opportunities for probing the Higgs portal as it relates to these questions in cosmology at the LHC and possible future colliders.

Constraints on the CP-Violating MSSM

We discuss the prospects for observing CP violation in the MSSM with six CP-violating phases, using a geometric approach to maximise CP-violating observables subject to the experimental upper bounds on electric dipole moments. We consider constraints from Higgs physics, flavour physics, the dark matter relic density and spin-independent scattering cross section with matter.

Search for neutral Higgs bosons decaying to tau pairs produced in association with b-quarks at √s=1.96 TeV

Energy Technology Data Exchange (ETDEWEB)

Herner, Kenneth Richard [Stony Brook Univ., NY (United States)

2008-12-01

We report results from a search for neutral Higgs bosons decaying to tau pairs produced in association with a b-quark in 1.6 fb^-1 of data taken from June 2006 to March 2008 with the D0 detector at Fermi National Accelerator Laboratory. The final state includes a muon, hadronically decaying tau, and jet identified as coming from a b-quark. We set cross section times branching ratio limits on production of such neutral Higgs bosons Φ in the mass range from 90 GeV to 160 GeV. Exclusion limits are set at the 95% Confidence Level for several supersymmetric scenarios.

Possible origin of a natural conservation of flavor in an interaction with neutral Higgs bosons

International Nuclear Information System (INIS)

Ural'tsev, N.G.

1983-01-01

In technicolor models the masses of the neutral pseudo-Goldstone bosons which interact with quarks and leptons without flavor conservation automatically acquire an order of magnitude Mapprox.(m/sub q/#betta#/sub TC/)/sup 1/2/approx.0.2--1 TeV through the Yukawa interaction. As a result, an effective Lagrangian which conserves only light Higgs bosons satisfies the condition of natural flavor conservation

Data from the CPLEAR experiment, together with the most recent world averages for some of the neutral-kaon parameters, were constrained with the Bell--Steinberger (or unitarity) relation, allowing the T-violation parameter $\\ree$ and the CPT-violation parameter $\\imd$ of the neutral-kaon mixing matrix to be determined with an increased accuracy: $\\ree = (164.9 \\pm 2.5)\\times 10^{-5}$, $\\imd = ( 2.4 \\pm 5.0)\\times 10^{-5}$. Moreover, the constraint allows the CPT-violation parameter for the neutral-kaon semileptonic decays, $\\rey$, to be determined for the first time. The $\\Delta S \

A search for lepton flavour violating decays of the Higgs boson in the $\\mu\\tau$ and $\\mathrm{e}\\tau$ decay modes is presented. The search is based on a data set corresponding to an integrated luminosity of 35.9 fb$^{-1}$ of proton-proton collisions collected with the CMS detector in 2016, at a centre-of-mass energy of 13 TeV. No significant excess over the standard model expectation is observed. The observed (expected) upper limits on the lepton flavour violating branching fractions of the Higgs boson are $\\mathcal{B}(\\mathrm{H}\\to\\mu\\tau) < $ 0.25% (0.25%) and $\\mathcal{B}(\\mathrm{H}\\to\\mathrm{e}\\tau) < $ 0.61% (0.37%), at 95% confidence level. These results are used to derive upper limits on the off-diagonal $\\mu\\tau$ and $\\mathrm{e}\\tau$ Yukawa couplings $\\sqrt{|{Y_{\\mu\\tau}}|^{2}+|{Y_{\\tau\\mu}}|^{2}} < 1.43\\times 10^{-3}$ and $\\sqrt{|{Y_{\\mathrm{e}\\tau}}|^{2}+|{Y_{\\tau\\mathrm{e}}}|^{2}} < 2.26\\times 10^{-3}$ at 95% confidence level. The limits on the lepton flavour violating branching fractio...

Lepton masses and mixings in orbifold models with three Higgs families

We analyse the phenomenological viability of heterotic Z 3 orbifolds with two Wilson lines, which naturally predict three supersymmetric families of matter and Higgs fields. Given that these models can accommodate realistic scenarios for the quark sector avoiding potentially dangerous flavour-changing neutral currents, we now address the leptonic sector, finding that viable orbifold configurations can in principle be obtained. In particular, it is possible to accomodate present data on charged lepton masses, while avoiding conflict with lepton flavour-violating decays. Concerning the generation of neutrino masses and mixings, we find that Z 3 orbifolds offer several interesting possibilities

Intermediate-mass Higgs boson and isosinglet neutral heavy lepton signals at hadron supercolliders

International Nuclear Information System (INIS)

Bhattacharya, G.

1992-01-01

The signals for the Standard Model intermediate-mass Higgs boson and isosinglet neutral heavy leptons at the forthcoming hadron supercolliders-the Superconducting Super Collider (SSC) and the CERN Large Hadron Collider (LHC), are studied. The author studies inclusive production of the Standard Model Higgs boson in the intermediate-mass region (M W approx-lt m H approx-lt 2M Z ) and its subsequent decay into two on- or off-shell W bosons that decay leptonically. Backgrounds from continuum W pair production and top quark pair production with semileptonic decays are investigated. The author concludes the Higgs boson signal may be observed via the decay H → W*W* → (ell bar v ell ) (bar ell' v' ell ) at the SSC for 145 GeV H approx-lt 2M Z and at the LHC for 150 GeV H approx-lt 2M Z if m t > 150 GeV. The author analyzes the search and discovery potential of isosinglet neutral heavy leptons (NHLs) produced via real or virtual W decay at pp supercolliders. The author considers the signal resulting from the leptonic decay of the NHL, and the two major backgrounds-continuum WZ, Wγ production and t bar tj production, where j is a hadronic jet. The decay patterns of NHL depend on its mass M N , and different search strategies are needed for the two mass regions M N W and M N > M Z . The author finds for m t ≥ 150 (200) GeV the signal is observable for M N ≤ 60 (70) GeV in the mass-region M N W , and up to M N ≅ 110 GeV for M N > M W , at both SSC and LHC. It is shown the non-observance of the signal (with a 4σ statistical significance) in the region M N W could put upper limits on the NHL coupling constants that would be an improvement over the limits obtainable from the CERN Large Electron Positron Collider (LEP I)

We study the cosmological perturbations created during the New Higgs inflationary phase. In the New Higgs Inflation, the Higgs boson is kinetically coupled to the Einstein tensor and only three perturbative degrees of freedom, a scalar and two tensorial (gravitational waves), propagate during Inflation. Scalar perturbations are found to match the latest WMAP-7yrs data within Standard Model Higgs parameters. Primordial gravitational waves also, although propagating with superluminal speed, are consistent with present data. Finally, we estimate the values of the parameter of the New Higgs Inflation in relation to the Higgs mass, the spectral index and amplitude of the primordial scalar perturbations showing that the unitarity bound of the theory is not violated.

A search for the lightest neutral CP-even and neutral CP-odd Higgs bosons of the Minimal Supersymmetric Standard Model is performed using 216.6 pb-1 of data collected with the L3 detector at LEP at centre-of-mass energies between 203 and 209 GeV. No indication of a signal is found. Including our results from lower centre-of-mass energies, lower limits on the Higgs boson masses are set as a function of tan(beta) for several scenarios. For tan(beta) greater than 0.7 they are mh > 84.5 GeV and mA > 86.3 GeV at 95% confidence level.

Lepton flavor violating Higgs boson decays in seesaw models: New discussions

Directory of Open Access Journals (Sweden)

N.H. Thao

2017-08-01

Full Text Available The lepton flavor violating decay of the Standard Model-like Higgs boson (LFVHD, h→μτ, is discussed in seesaw models at the one-loop level. Based on particular analytic expressions of Passarino–Veltman functions, the two unitary and 't Hooft Feynman gauges are used to compute the branching ratio of LFVHD and compare with results reported recently. In the minimal seesaw (MSS model, the branching ratio was investigated in the whole valid range 10−9–1015 GeV of new neutrino mass scale mn6. Using the Casas–Ibarra parameterization, this branching ratio enhances with large and increasing mn6. But the maximal value can reach only order of 10−11. Interesting relations of LFVHD predicted by the MSS and inverse seesaw (ISS model are discussed. The ratio between two LFVHD branching ratios predicted by the ISS and MSS is simply mn62μX−2, where μX is the small neutrino mass scale in the ISS. The consistence between different calculations is shown precisely from analytical approach.

Analyses on the search for neutral Higgs bosons and on the Z pair production in qqττ final states in e+e- annihilation at LEP II

Baumann, S.

2000-11-01

The data taken with the OPAL detector at LEP at center of mass energies between 183 and 202 GeV during the years 1997-1999 have been used to search for neutral Higgs-Bosons and to investigate the pair production of Z-bosons. The analyses performed concentrate on final states with two τ-leptons and two quark-jets. Neutral Higgs boson production has been searched for in the framework of the standard model where the Higgs boson is produced in association with a Z boson. Also the Higgs production of the minimal supersymmetric extension of the standard model (MSSM) has been investigated via the pair production process of the h and A Higgs bosons. No significant excess of the number of observed events compared to the background expectation has been observed. Limits on the masses of Higgs bosons are derived from the combination of all search channels. In addition the pair production of Z bosons which is the most important background process in the search for Higgs bosons has been investigated. The production cross section and limits on anomalous couplings on the ZZZ- and ZZγ-vertices which are not predicted by the standard model are derived from the combination of channels. (orig.)

Results of searches for super-symmetric and other beyond the Standard Model Higgs boson searches from ATLAS and CMS experiments at the LHC arc presented. Some Standard Model (SM) higgs searches are reinterpreted in SM with four quark generations and fermio­ phobic models. Stringent limits) covering a large portion of the allowed parameter space in (MA, tan/3) plane are set for MSSM neutral higgs bosons decaying to T-lepton pairs, and charged higgs boson decaying to TV. Limits are set on a light NMSSM neutral higgs boson and on doubly charged higgs bosons predicted in some models are also set.

Phenomenology of CP violation

International Nuclear Information System (INIS)

Ecker, G.

1987-01-01

A short survey of the theoretical status of CP violation is presented. The Standart Model is confronted with the present experimental situation. Possible future tests of our notions of CP violation are discussed, concentrating on rare K decays. Other promising reactions such as B decays are briefly reviewed. Among alternative models of CP violation, multi-Higgs extensions of the Standart Model, left-right symmetric gauge theories and minimal SUSY models are discussed. Finally, the relevance of generalized CP invariance is emphasized. 64 refs., 7 figs. (Author)

Search for BSM Higgs bosons in fermion decay modes with ATLAS

Straessner, Arno; The ATLAS collaboration

2017-01-01

Many physics models beyond the Standard Model (BSM) predict an extension of the Higgs sector, like the general 2-Higgs Doublet Model (2HDM) or supersymmetric models. In case of one additional Higgs doublet, there are five physical Higgs bosons: two CP neutral states (h,H), one CP odd state (A) and two charged Higgs bosons (H±). Typically, the already observed Higgs boson is identified with the h Higgs boson, while the others are assumed to be heavy. This presentation is reporting on recent results of direct searches for heavy neutral and charged Higgs bosons by the ATLAS Collaboration, in particular analyzing direct Higgs boson decays to fermions, like $H^\\pm \\to \\tau\

Higgs phenomenology in the minimal S U (3 )L×U (1 )X model

Okada, Hiroshi; Okada, Nobuchika; Orikasa, Yuta; Yagyu, Kei

We investigate the phenomenology of a model based on the S U (3 )c×S U (3 )L×U (1 )X gauge theory, the so-called 331 model. In particular, we focus on the Higgs sector of the model which is composed of three S U (3 )L triplet Higgs fields and is the minimal form for realizing a phenomenologically acceptable scenario. After the spontaneous symmetry breaking S U (3 )L×U (1 )X→S U (2 )L×U (1 )Y , our Higgs sector effectively becomes that with two S U (2 )L doublet scalar fields, in which the first- and the second-generation quarks couple to a different Higgs doublet from that which couples to the third-generation quarks. This structure causes the flavor-changing neutral current mediated by Higgs bosons at the tree level. By taking an alignment limit of the mass matrix for the C P -even Higgs bosons, which is naturally realized in the case with the breaking scale of S U (3 )L×U (1 )X much larger than that of S U (2 )L×U (1 )Y, we can avoid current constraints from flavor experiments such as the B0-B¯ 0 mixing even for the Higgs bosons masses that are O (100 ) GeV . In this allowed parameter space, we clarify that a characteristic deviation in quark Yukawa couplings of the Standard Model-like Higgs boson is predicted, which has a different pattern from that seen in two Higgs doublet models with a softly broken Z2 symmetry. We also find that the flavor-violating decay modes of the extra Higgs boson, e.g., H /A →t c and H±→t s , can be dominant, and they yield the important signature to distinguish our model from the two Higgs doublet models.

Violation of the Appelquist-Carazzone decoupling in a nonsupersymmetric grand unified theory

International Nuclear Information System (INIS)

Chankowski, Piotr H.; Wagner, Jakub

2008-01-01

We point out that in nonsupersymmetric grand unified theories, in which the SU(5) gauge symmetry is broken down to the standard model gauge group by a 24 Higgs multiplet the Appelquist-Carazzone decoupling is violated. This is because the SU(2) L Higgs triplet contained in the 24 acquires a dimension-full coupling to the SU(2) L Higgs doublets which is proportional to the grand unified symmetry breaking vacuum expectation value. As a result, at one-loop heavy gauge and Higgs fields contribution to tadpoles generates a vacuum expectation value of the triplet which is not suppressed for V→∞ and violates the custodial symmetry

Parity violating weak neutral-current effects in elastic e-12C scattering. Progress report, April 15, 1981-February 28, 1982

International Nuclear Information System (INIS)

Lubell, M.S.

Unified gauge theories of the electro-weak interaction incorporate a neutral weak current, which, although many orders of magnitude smaller than the neutral-electromagnetic current, can be isolated through the manifestation of its parity violating effects. As a consequence, neutral current parity violation experiments provide direct access to the measurement of the weak coupling constants as well as fundamental tests of the unified theories. The verification of unified theories at low energies is a crucial prerequisite of the application of these theories to the range of higher energies where the W+- and the Z 0 are predicted to exist. One highly sensitive measurement of parity violation in the neutral current sector is provided by the determination of the asymmetry, A = (sigma + - sigma - )/(sigma + + sigma - ), for elastic scattering of positive (+) and negative (-) helicity electrons from 12 C nuclei. We have been pursuing such a program at the Bates Electron Accelerator with the goal of measuring A to a precision of approx. 10 -7 . By contrast, the standard model predicts a value for A of approx. 2 x 10 -6

The supersymmetric Higgs sector and $B-\\overline{B}$ mixing for large tan $\\beta$

Gorbahn, Martin; Nierste, Ulrich; Trine, Stephanie

2009-01-01

We match the Higgs sector of the most general flavour breaking and CP violating minimal supersymmetric standard model (MSSM) onto a generic two-Higgs-doublet model, paying special attention to the definition of tan beta in the effective theory. In particular no tan beta-enhanced loop corrections appear in the relation to tan beta defined in the DRbar scheme in the MSSM. The corrections to the Higgs-mediated flavour-changing amplitudes which result from this matching are especially relevant for the B_d and B_s mass differences dM_s,d for minimal flavour violation, where the superficially leading contribution vanishes. We give a symmetry argument to explain this cancellation and perform a systematic study of all Higgs-mediated effects, including Higgs loops. The corrections to dM_s are at most 7% for mu>0 and M_A tau^+ nu or B -> X_s gamma. We further update supersymmetric loop corrections to the Yukawa couplings, where we include all possible CP-violating phases and correct errors in the literature. The possi...

Review of searches for Higgs bosons and beyond the standard model physics at the Tevatron

International Nuclear Information System (INIS)

Duperrin, Arnaud

2009-01-01

The energy frontier is currently at the Fermilab Tevatron accelerator, which collides protons and antiprotons at a center-of-mass energy of 1.96 TeV. The luminosity delivered to the CDF and DOe experiments has now surpassed the 4 fb -1 . This paper reviews the most recent direct searches for Higgs bosons and beyond-the-standard-model (BSM) physics at the tevatron. The results reported correspond to an integrated luminosity of up to 2.5 fb -1 of Run II data collected by the two Collaborations. Searches covered include the standard model (SM) Higgs boson (including sensitivity projections), the neutral Higgs bosons in the minimal supersymmetric extension of the standard model (MSSM), charged Higgs bosons and extended Higgs models, supersymmetric decays that conserve or violate R-parity, gauge-mediated supersymmetric breaking models, long-lived particles, leptoquarks, compositeness, extra gauge bosons, extra dimensions, and finally signature-based searches. Given the excellent performance of the collider and the continued productivity of the experiments, the Tevatron physics potential looks promising for discovery with the coming larger data sets. In particular, evidence for the SM Higgs boson could be obtained if its mass is light or near 160 GeV. The observed (expected) upper limits are currently a factor of 3.7 (3.3) higher than the expected SM Higgs boson cross section at m H =115 GeV and 1.1(1.6) at m H =160 GeV at 95% C.L. (orig.)

Analysis of the phase structure in extended Higgs models

Energy Technology Data Exchange (ETDEWEB)

Seniuch, M.

2006-07-07

We study the generation of the baryon asymmetry in the context of electroweak baryogenesis in two different extensions of the Standard Model. First, we consider an effective theory, in which the Standard Model is augmented by an additional dimension-six Higgs operator. The effects of new physics beyond a cut-off scale are parameterized by this operator. The second model is the two-Higgs-doublet model, whose particle spectrum is extended by two further neutral and two charged heavy Higgs bosons. In both cases we focus on the properties of the electroweak phase transition, especially on its strength and the profile of the nucleating bubbles. After reviewing some general aspects of the electroweak phase transition and baryogenesis we derive the respective thermal effective potentials to one-loop order. We systematically study the parameter spaces, using numerical methods, and compute the strength of the phase transition and the wall thickness as a function of the Higgs masses. We find a strong first order transition for a light Higgs state with a mass up to about 200 GeV. In case of the dimension-six model the cut-off scale has to stay between 500 and 850 GeV, in the two-Higgs-doublet model one needs at least one heavy Higgs mass of 300 GeV. The wall thickness varies for both theories in the range roughly from two to fifteen, in units of the inverse critical temperature. We also estimate the size of the electron and neutron electric dipole moments, since new sources of CP violation give rise to them. In wide ranges of the parameter space we are not in conflict with the experimental bounds. Finally the baryon asymmetry, which is predicted by these models, is related to the Higgs mass and the other appropriate input parameters. In both models the measured baryon asymmetry can be achieved for natural values of the model parameters. (orig.)

Higgs detectability in the extended supersymmetric standard model

International Nuclear Information System (INIS)

Kamoshita, Jun-ichi

1995-01-01

Higgs detectability at a future linear collider are discussed in the minimal supersymmetric standard model (MSSM) and a supersymmetric standard model with a gauge singlet Higgs field (NMSSM). First, in the MSSM at least one of the neutral scalar Higgs is shown to be detectable irrespective of parameters of the model in a future e + e - linear collider at √s = 300-500 GeV. Next the Higgs sector of the NMSSM is considered, since the lightest Higgs boson can be singlet dominated and therefore decouple from Z 0 boson it is important to consider the production of heavier Higgses. It is shown that also in this case at least one of the neutral scalar Higgs will be detectable in a future linear collider. We extend the analysis and show that the same is true even if three singlets are included. Thus the detectability of these Higgs bosons of these models is guaranteed. (author)

Search for Neutral MSSM Higgs Bosons Decaying to ${\\tau}_{had} {\\tau}_{had}$ in $\\sqrt{s}$ = 7 TeV Proton–Proton Collisions with the ATLAS Detector

CERN Document Server

AUTHOR|(INSPIRE)INSPIRE-00013837; Jakobs, Karl

In this thesis a search for the neutral Higgs bosons of the Minimal Supersymmetric Standard Model (MSSM) in the h/A/H -> tau_had tau_had decay channel is described. The analysis is based on a sample of proton-proton collisions at a centre-of-mass energy of 7 TeV recorded with the ATLAS detector at the Large Hadron Collider. The data were recorded in 2011 and correspond to an integrated luminosity of 4.7 fb^-1. Final states with two hadronic tau-lepton decays requiring either the presence or absence of b-jets are considered and the selection is optimised for Higgs bosons in b-quark associated and gluon-fusion production. No statistically significant excess over the expected background is observed and exclusion limits at the 95% confidence level are derived in combination with the h/A/H -> mu mu, h/A/H -> tau_e tau_mu and h/A/H -> tau_lep tau_had decay channels. The exclusion limits are shown for the production cross section of a generic neutral Higgs boson, phi, as a function of the Higgs boson mass and for h/...

A flavor sector for the composite Higgs

Energy Technology Data Exchange (ETDEWEB)

Vecchi, Luca, E-mail: vecchi@lanl.gov

2013-11-25

We discuss flavor violation in large N Composite Higgs models. We focus on scenarios in which the masses of the Standard Model fermions are controlled by hierarchical mixing parameters, as in models of Partial Compositeness. We argue that a separation of scales between flavor and Higgs dynamics can be employed to parametrically suppress dipole and penguin operators, and thus effectively remove the experimental constraints arising from the lepton sector and the neutron EDM. The dominant source of flavor violation beyond the Standard Model is therefore controlled by 4-fermion operators, whose Wilson coefficients can be made compatible with data provided the Higgs dynamics approaches a “walking” regime in the IR. Models consistent with all flavor and electroweak data can be obtained with a new physics scale within the reach of the LHC. Explicit scenarios may be realized in a 5D framework, the new key ingredient being the introduction of flavor branes where the wave functions of the bulk fermions end.

2017-01-01

A search is presented for additional neutral Higgs bosons in the di-$\\tau$ final state in pp collisions at the LHC. The search is performed in the context of the minimal supersymmetric extension of the standard model (MSSM), on the data collected with the CMS detector in 2016 at a center-of-mass energy of $13~\\mathrm{TeV}$, corresponding to an integrated luminosity of $35.9~\\mathrm{fb}^{-1}$. To enhance the sensitivity to neutral MSSM Higgs bosons the search includes the case where the Higgs boson is produced in association with b quarks. No significant deviation above the expected background is observed. Model-independent limits are set on the product of the cross section and branching fraction for the production via gluon-fusion or in association with b quarks. These limits range from $18~\\mathrm{pb}$ (at $90~\\mathrm{GeV}$) to $3.5\\times 10^{-3}~\\mathrm{pb}$ (at $3.2~\\mathrm{TeV}$) for gluon-fusion and from $15~\\mathrm{pb}$ (at $90~\\mathrm{GeV}$) to $2.5\\times 10^{-3}~\\mathrm{pb}$ (at $3.2~\\mathrm{TeV}$) fo...

Three-body decays of Higgs bosons at LEP2 and application to a hidden fermiophobic Higgs

International Nuclear Information System (INIS)

Akeroyd, A.G.

1999-01-01

We study the decays of Higgs bosons to a lighter Higgs boson and a virtual gauge boson in the context of the non-supersymmetric two-Higgs doublet model (2HDM). We consider the phenomenological impact at LEP2 and find that such decays, when open, may be dominant in regions of parameter space and thus affect current Higgs boson search techniques. Three-body decays would be a way of producing light neutral Higgs bosons which have so far escaped detection at LEP due to suppressed couplings to the Z, and are of particular importance in the 2HDM (Model I) which allows both a light fermiophobic Higgs and a light charged scalar

Collider signatures of flavorful Higgs bosons

International Nuclear Information System (INIS)

Altmannshofer, Wolfgang; Eby, Joshua; Gori, Stefania; Lotito, Matteo

2016-01-01

Motivated by our limited knowledge of the Higgs couplings to the first two generation fermions, we analyze the collider phenomenology of a class of two Higgs doublet models (2HDMs) with a nonstandard Yukawa sector. One Higgs doublet is mainly responsible for the masses of the weak gauge bosons and the third-generation fermions, while the second Higgs doublet provides mass for the lighter fermion generations. The characteristic collider signatures of this setup differ significantly from well-studied 2HDMs with natural flavor conservation, flavor alignment, or minimal flavor violation. New production mechanisms for the heavy scalar, pseudoscalar, and charged Higgs involving second-generation quarks can become dominant. The most interesting decay modes include H/A → cc,tc,μμ,τμ and H"± → cb,cs,μν. As a result, searches for low-mass dimuon resonances are currently among the best probes of the heavy Higgs bosons in this setup.

The final results of the ALEPH search for the Standard Model Higgs boson at LEP, with data collected in the year 2000 at centre-of-mass energies up to 209,GeV, are presented. The changes with respect to the preceding publication are described and a complete study of systematic effects is reported. The findings of this final analysis confirm the preliminary results published in November 2000 shortly after the closing down of the LEP collider: a significant excess of events is observed, consistent with the production of a $115, Gcs$ Standard Model Higgs boson.% The final results of the searches for the neutral Higgs bosons of the MSSM are also reported, in terms of limits on $mh$, $mA$ and $anb$.% Limits are also set on $mh$ in the case of invisible decays.

Spontaneous CP violation on the lattice

Laine, Mikko

2000-01-01

At finite temperatures around the electroweak phase transition, the thermodynamics of the MSSM can be described by a three-dimensional two Higgs doublet effective theory. This effective theory has a phase where CP is spontaneously violated. We study spontaneous CP violation with non-perturbative lattice simulations, and analyse whether one could end up in this phase for any physical MSSM parameter values.

Light Higgs bosons at LEP

Ekspong, G.

1981-11-01

Among possible production reactions for neutral Higgs bosons it is known that e + e - →Z 0 +H 0 offers advantages of relatively high production cross section and low background from other reactions. With Z 0 decaying to two electrons, which are measured, the existence of a Higgs candidate will be seen as a peak in the missing mass spectrum. It is shown that a sufficiently good mass resolution is obtainable to make a search for Higgs feasible at LEP. In its first phase, the energy of LEP limits the search to Higgs bosons of mass around 10 GeV. (Auth.)

Summary of non-SM Higgs boson searches from the ATLAS and CMS experiments

Davey, W.

2014-01-01

A review of searches for non-standard Model Higgs bosons conducted at the Large Hadron Collider is presented. The searches use datasets corresponding to integrated luminosities up to 5 fb -1 collected by the ATLAS and CMS experiments during 7 TeV proton-proton collisions. Searches for neutral and charged MSSM Higgs bosons, the light CP-odd neutral Higgs boson of the NMSSM, fermio-phobic Higgs bosons and doubly charged Higgs bosons are conducted. No evidence for these signals have been observed. (author)

Disentangling Higgs-Top Couplings in Associated Production

CERN Document Server

Ellis, John; Sakurai, Kazuki; Takeuchi, Michihisa

2014-01-01

In the presence of CP violation, the Higgs-top coupling may have both scalar and pseudoscalar components, $\\kappa_t$ and ${\\tilde \\kappa_t}$, which are bounded indirectly but only weakly by the present experimental constraints on the Higgs-gluon-gluon and Higgs-$\\gamma$-$\\gamma$ couplings, whereas upper limits on electric dipole moments provide strong additional indirect constraints on ${\\tilde \\kappa_t}$, if the Higgs-electron coupling is similar to that in the Standard Model and there are no cancellations with other contributions. We discuss methods to measure directly the scalar and pseudoscalar Higgs-top couplings by measurements of Higgs production in association with ${\\bar t} t$, single $t$ and single ${\\bar t}$ at the LHC. Measurements of the total cross sections are very sensitive to variations in the Higgs-top couplings that are consistent with the present indirect constraints, as are invariant mass distributions in ${\\bar t} t H$, $tH$ and ${\\bar t} H$ final states. We also investigate the addition...

Higgs mediated lepton flavor violating tau decays τ→μγ and τ→μγγ in effective theories

Aranda, J. I.; Tututi, E. S.; Ramirez-Zavaleta, F.; Toscano, J. J.

2008-01-01

The size of the branching ratios for the τ→μγ and τ→μγγ decays induced by a lepton flavor violating Higgs interaction Hτμ is studied in the framework of effective field theories. The best constraint on the Hτμ vertex, derived from the know measurement on the muon anomalous magnetic moment, is used to impose the upper bounds Br(τ→μγ) -10 and Br(τ→μγγ) -12 , which are more stringent than current experimental limits on this class of transitions.

The flavor of the composite pseudo-goldstone Higgs

International Nuclear Information System (INIS)

Csaki, Csaba; Weiler, Andreas; Falkowski, Adam

2008-01-01

We study the flavor structure of 5D warped models that provide a dual description of a composite pseudo-Goldstone Higgs. We first carefully re-examine the flavor constraints on the mass scale of new physics in the standard Randall-Sundrum-type scenarios, and find that the KK gluon mass should generically be heavier than about 21 TeV. We then compare the flavor structure of the composite Higgs models to those in the RS model. We find new contributions to flavor violation, which while still are suppressed by the RS-GIM mechanism, will enhance the amplitudes of flavor violations. In particular, there is a kinetic mixing term among the SM fields which (although parametrically not enhanced) will make the flavor bounds even more stringent than in RS. This together with the fact that in the pseudo-Goldstone scenario Yukawa couplings are set by a gauge coupling implies the KK gluon mass to be at least about 33 TeV. For both the RS and the composite Higgs models the flavor bounds could be stronger or weaker depending on the assumption on the value of the gluon boundary kinetic term. These strong bounds seem to imply that the fully anarchic approach to flavor in warped extra dimensions is implausible, and there have to be at least some partial flavor symmetries appearing that eliminate part of the sources for flavor violation. We also present complete expressions for the radiatively generated Higgs potential of various 5D implementations of the composite Higgs model, and comment on the 1-5 percent level tuning needed in the top sector to achieve a phenomenologically acceptable vacuum state.

Higgs-gauge boson interactions in the economical 3-3-1 model

2006-01-01

Interactions among the standard model gauge bosons and scalar fields in the framework of the SU(3) C xSU(3) L xU(1) X gauge model with minimal (economical) Higgs content are presented. From these couplings, all scalar fields including the neutral scalar h and the Goldstone bosons can be identified and their couplings with the usual gauge bosons such as the photon, the charged W ± , and the neutral Z, without any additional conditions, are recovered. In the effective approximation, the full content of the scalar sector can be recognized. The CP-odd part of the Goldstone associated with the neutral non-Hermitian bilepton gauge boson G X 0 is decoupled, while its CP-even counterpart has the mixing in the same way in the gauge boson sector. Masses of the new neutral Higgs boson H 1 0 and the neutral non-Hermitian bilepton X 0 are dependent on a coefficient of Higgs self-coupling (λ 1 ). Similarly, masses of the singly charged Higgs boson H 2 ± and of the charged bilepton Y ± are proportional through a coefficient of Higgs self-interaction (λ 4 ). The hadronic cross section for production of this Higgs boson at the CERN LHC in the effective vector boson approximation is calculated. Numerical evaluation shows that the cross section can exceed 260 fb

Exploring CP violation in the MSSM.

Science.gov (United States)

Arbey, Alexandre; Ellis, John; Godbole, Rohini M; Mahmoudi, Farvah

We explore the prospects for observing CP violation in the minimal supersymmetric extension of the Standard Model (MSSM) with six CP-violating parameters, three gaugino mass phases and three phases in trilinear soft supersymmetry-breaking parameters, using the CPsuperH code combined with a geometric approach to maximise CP-violating observables subject to the experimental upper bounds on electric dipole moments. We also implement CP-conserving constraints from Higgs physics, flavour physics and the upper limits on the cosmological dark matter density and spin-independent scattering. We study possible values of observables within the constrained MSSM (CMSSM), the non-universal Higgs model (NUHM), the CPX scenario and a variant of the phenomenological MSSM (pMSSM). We find values of the CP-violating asymmetry [Formula: see text] in [Formula: see text] decay that may be as large as 3 %, so future measurements of [Formula: see text] may provide independent information about CP violation in the MSSM. We find that CP-violating MSSM contributions to the [Formula: see text] meson mass mixing term [Formula: see text] are in general below the present upper limit, which is dominated by theoretical uncertainties. If these could be reduced, [Formula: see text] could also provide an interesting and complementary constraint on the six CP-violating MSSM phases, enabling them all to be determined experimentally, in principle. We also find that CP violation in the [Formula: see text] and [Formula: see text] couplings can be quite large, and so may offer interesting prospects for future [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text] colliders.

Search for a lighter Higgs boson in Two Higgs Doublet Models

We consider present constraints on Two Higgs Doublet Models, both from the LHC at Run 1 and from other sources in order to explore the possibility of constraining a neutral scalar or pseudo-scalar particle lighter than the 125 GeV Higgs boson. Such a lighter particle is not yet completely excluded by present data. We show with a simplified analysis that some new constraints could be obtained at the LHC if such a search is performed by the experimental collaborations, which we therefore encourage to continue carrying out light diphoton resonance searches at √s=13 TeV in the context of Two Higgs Doublet Models.

A search for neutral Higgs bosons has been performed with the OPAL detector at LEP, using approximately 170 pb-1 of e+e- collision data collected at sqrt(s)~189GeV. Searches have been performed for the Standard Model (SM) process e+e- to H0Z0 and the MSSM processes e+e- to H0Z0, A0h0. The searches are sensitive to the b b-bar and tau antitau decay modes of the Higgs bosons, and also to the MSSM decay mode h0 to A0A0. OPAL search results at lower centre-of-mass energies have been incorporated in the limits we set, which are valid at the 95% confidence level. For the SM Higgs boson, we obtain a lower mass bound of 91.0 GeV. In the MSSM, our limits are mh>74.8GeV and mA>76.5GeV, assuming tan(beta)>1, that the mixing of the scalar top quarks is either zero or maximal, and that the soft SUSY-breaking masses are 1 TeV. For the case of zero scalar top mixing, we exclude values of tan(beta) between 0.72 and 2.19.

2018-05-15

We introduce the Hyperbolic Higgs, a novel solution to the little hierarchy problem that features Standard Model neutral scalar top partners. At one-loop order, the protection from ultraviolet sensitivity is due to an accidental non-compact symmetry of the Higgs potential that emerges in the infrared. Once the general features of the effective description are detailed, a completion that relies on a five dimensional supersymmetric framework is provided. Novel phenomenology is compared and contrasted with the Twin Higgs scenario.

One-loop contributions to neutral Higgs decay h→μτ

Phan, K. H.; Hung, H.T.; Hue, L.T.

2016-01-01

In calculating one-loop contributions to amplitudes of the lepton-flavor violating decays of the neutral Higgses (LFVHD) to different flavor charged leptons, the analytic expressions can be written in term of Passarino–Veltman functions. Then, they can be computed numerically by LoopTools [1]. Another approach is using suitable analytic expressions established for just this particular case. We compare numerical results obtained from LoopTools and those computed by different expressions that have been applied recently. Then we derive the preferable ones that are applicable for large ranges of free parameters introduced in extensions of the standard model. For illustration, the LFVHD in a simple model, which has been discussed recently, will be investigated more precisely.

A search is presented for additional neutral Higgs bosons in the $\\tau\\tau$ final state in proton-proton collisions at the LHC. The search is performed in the context of the minimal supersymmetric extension of the standard model (MSSM), using the data collected with the CMS detector in 2016 at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb$^{-1}$. To enhance the sensitivity to neutral MSSM Higgs bosons, the search includes production of the Higgs boson in association with b quarks. No significant deviation above the expected background is observed. Model-independent limits at 95% confidence level (CL) are set on the product of the branching fraction for the decay into $\\tau$ leptons and the cross section for the production via gluon fusion or in association with b quarks. These limits range from 18 pb at 90 GeV to 3.5 fb at 3.2 TeV for gluon fusion and from 15 pb (at 90 GeV) to 2.5 fb (at 3.2 TeV) for production in association with b quarks. In the ${m_{\\text{h}}^{\\tex...

CP-violating top quark couplings at future linear $e^+e^-$ colliders

We study the potential of future lepton colliders to probe violation of the CP symmetry in the top quark sector. In certain extensions of the Standard Model, such as the two-Higgs-doublet model (2HDM), sizeable anomalous top quark dipole moments can arise, that may be revealed by a precise measurement of top quark pair production. We present results from detailed Monte Carlo studies for the ILC at 500 GeV and CLIC at 380 GeV and use parton level simulations to explore the potential of high-energy operation. We find that precise measurements in $e^+e^- \\rightarrow t \\bar{t}$ production with subsequent decay to lepton plus jets final states can provide sufficient sensitivity to detect Higgs-boson-induced CP violation in a viable two-Higgs-doublet model. The potential of a linear $e^+e^-$ collider to detect CP-violating electric and weak dipole form factors of the top quark exceeds the prospects of the HL-LHC by over an order of magnitude.

Flavor with a light dynamical "Higgs particle"

CERN Document Server

Alonso, R.; Merlo, L.; Rigolin, S.; Yepes, J.

2013-01-01

The Higgs-fermion couplings are sensitive probes of possible new physics behind a stable light Higgs particle. It is then essential to identify the flavour pattern of those interactions. We consider the case in which a strong dynamics lies behind a light Higgs, and explore the implications within the Minimal Flavour Violation ansatz. The dominant effects on flavour-changing Higgs-fermion couplings stem in this context from operators with mass dimension <6, and we analyze all relevant chiral operators up to that order, including loop-corrections induced by 4-dimensional ones. Bounds on the operator coefficients are derived from a plethora of low-energy flavour transitions, providing a guideline on which flavour-changing Higgs interactions may be open to experimental scrutiny. In particular, the coefficient of a genuinely CP-odd operator is only softly constrained and therefore its impact is potentially interesting.

Search for lepton-flavour violating decays of the Higgs boson at the LHC

International Nuclear Information System (INIS)

Vanhoefer, Annika

2017-05-01

In this thesis, a search for lepton-flavour violating (LFV) decays of the Higgs boson to an electron and a tau lepton, denoted as eτ, is presented. LFV decays of the Higgs boson are forbidden in the Standard Model of particle physics (SM). However, extensions of the SM, such as multi-Higgs doublet models, can introduce LFV Yukawa couplings. The search is performed for tau decays to a muon and corresponding neutrinos, denoted as eτ_μ. Proton-proton collision data were collected with the CMS detector in 2012 and 2015, while the LHC was operating at a centre-of-mass energy of √(s)=8 TeV and √(s)=13 TeV, respectively, accounting for integrated luminosities of 19.7 fb"-"1 and 2.3 fb"-"1. The dominant SM background contributions for this search are coming from the Drell-Yan process, misidentified leptons, and the top-quark pair-production process. Top-quarks predominantly decay into a b quark and a W boson. Jets originating from b quarks can be identified, with processes including c-quark jets being the main background. The impact of heavy flavour modelling on the misidentification of c-quark jets as b-quark jets is studied. Differences in the charmed-hadron modelling regarding the production fraction, decay, and momentum fractions affect the discrimination. Furthermore, the misidentification probability is found to depend on the type of the charmed-hadron. In the LFV search, a new algorithm is developed to improve the optimisation of the event selection, which determines iteratively the best set of requirements on the discriminating variables. The search is done in three exclusive jet categories. Improvements on the modelling on the misidentified lepton background are studied. No excess of events is observed in the reconstructed mass distribution of the Higgs boson. An observed (expected) 95% CL upper limit on the branching fraction B(H→eτ)<0.74%(<0.85"+"0"."3"7_-_0_._2_5%) can be set using the collision data at √(s)=8 TeV. Results were combined with the

Parity-Violating Electron Deuteron Scattering and the Proton's Neutral Axial Vector Form Factor

International Nuclear Information System (INIS)

Ito, T.

2003-01-01

The authors report on a new measurement of the parity-violating asymmetry in quasielastic electron scattering from the deuteron at the backward angles at electron beam energy of 125 MeV [Q 2 =0.038 (GeV/c) 2 ]. This quantity provides a determination of the neutral weak axial vector form factor of the nucleon. In addition to the tree level amplitude associated with Z-exchange, the neutral weak axial vector form factor as measured in electron scattering can potentially receive large electroweak corrections, including the anapole moment, that are absent in neutrino scattering. The measured asymmetry A -3.51 ± 0.57 (stat) ± 0.58 (sys) ppm is consistent with theoretical predictions. We also report on updated results of the previous experiment at 200 MeV [Q 2 = 0.091 (GeV/c) 2 ] on a deuterium target. The updated results are also consistent with theoretical predictions on the neutral weal axial vector form factor

The discovery of the Higgs boson opens the door to new physics interacting via the Higgs Portal, including motivated scenarios relating to baryogenesis, dark matter, and electroweak naturalness. We systematically explore the collider signatures of singlet scalars produced via the Higgs Portal at the 14 TeV LHC and a prospective 100 TeV hadron collider. We focus on the challenging regime where the scalars are too heavy to be produced in the decays of an on-shell Higgs boson, and instead are produced primarily via an off-shell Higgs. Assuming these scalars escape the detector, promising channels include missing energy in association with vector boson fusion, monojets, and top pairs. We forecast the sensitivity of searches in these channels at √s=14 & 100 TeV and compare collider reach to the motivated parameter space of singlet-assisted electroweak baryogenesis, Higgs Portal dark matter, and neutral naturalness.

Radiative corrections to the masses of supersymmetric Higgs bosons

International Nuclear Information System (INIS)

Ellis, J.; Zwirner, F.

1991-01-01

The lightest neutral Higgs boson in the minimal supersymmetric extension of the standard model has a tree-level mass less than that of the Z 0 . We calculate radiative corrections to its mass and to that of the heavier CP-even neutral Higgs boson. We find large corrections that increase with the top quark and squark masses, and vary with the ratio of vacuum expectation values v 2 /v 1 . These radiative corrections can be as large as O(100) GeV, and have the effect of (i) invalidating lower bounds on v 2 /v 1 inferred from unsuccessful Higgs searches at LEP I, (ii) in many cases, increasing the mass of the lighter CP-even Higgs boson beyond m z , (iii) often, increasing the mass of the heavier CP-even Higgs boson beyond the LEP reach, into a range more accessible to the LHC or SSC.

Interference contributions to gluon initiated heavy Higgs production in the Two-Higgs-Doublet Model

International Nuclear Information System (INIS)

Greiner, Nicolas

2016-03-01

We discuss the production of a heavy neutral Higgs boson of a CP-conserving Two-Higgs-Doublet Model in gluon fusion and its decay into a four-fermion final state, gg(→VV)→e + e - π + π - /e + e - ν l anti ν l . We investigate the interference contributions to invariant mass distributions of the four-fermion final state and other relevant kinematical observables. The relative importance of the different contributions is quantified for the process in the on-shell approximation, gg→ZZ. We show that interferences of the heavy Higgs with the light Higgs boson and background contributions are essential for a correct description of the differential cross section. Even though they contribute below O(10%) to those heavy Higgs signal cross sections, to which the experiments at the Large Hadron Collider were sensitive in its first run, we find that they are sizeable in certain regions of the parameter space that are relevant for future heavy Higgs boson searches. In fact, the interference contributions can significantly enhance the experimental sensitivity to the heavy Higgs boson.

Search for lepton flavour violating decays of the Higgs boson to eτ and eμ in proton–proton collisions at s=8 TeV

Directory of Open Access Journals (Sweden)

V. Khachatryan

2016-12-01

Full Text Available A direct search for lepton flavour violating decays of the Higgs boson (H in the H→eτ and H→eμ channels is described. The data sample used in the search was collected in proton–proton collisions at s=8 TeV with the CMS detector at the LHC and corresponds to an integrated luminosity of 19.7 fb−1. No evidence is found for lepton flavour violating decays in either final state. Upper limits on the branching fractions, B(H→eτ<0.69% and B(H→eμ<0.035%, are set at the 95% confidence level. The constraint set on B(H→eτ is an order of magnitude more stringent than the existing indirect limits. The limits are used to constrain the corresponding flavour violating Yukawa couplings, absent in the standard model.

Constraints on the Lee-Wick Higgs sector

Carone, Christopher D.; Primulando, Reinard

2009-01-01

Lee-Wick partners to the standard model Higgs doublet may appear at a mass scale that is significantly lower than that of the remaining Lee-Wick partner states. The relevant effective theory is a two-Higgs doublet model in which one doublet has wrong-sign kinetic and mass terms. We determine bounds on this effective theory, including those from neutral B-meson mixing, b→X s γ, and Z→bb. The results differ from those of conventional two-Higgs doublet models and lead to meaningful constraints on the Lee-Wick Higgs sector.

Simulating the electroweak phase transition in the SU(2) Higgs model

Numerical simulations are performed to study the finite temperature phase transition in the SU(2) Higgs model on the lattice. In the presently investigated range of the Higgs boson mass, below 50 GeV, the phase transition turns out to be of first order and its strength is rapidly decreasing with increasing Higgs boson mass. In order to control the systematic errors, we also perform studies of scaling violations and of finite volume effects. (orig.)

International Nuclear Information System (INIS)

Kanemura, Shinya; Tsumura, Koji

2010-08-01

We study the LFV Higgs production processes e - γ → l - φ (l = μ, τ ;φ = H,A) as a probe of Higgs mediated LFV couplings at an electron-photon collider, where H and A are extra CP even and odd Higgs bosons, respectively, in the two Higgs doublet model. Under the constraints from the current data of muon and tau rare decay, the cross section can be significantly large. It would improve the experimental upper bounds on the effective LFV coupling constants. In addition, the chirality nature of the LFV Higgs coupling constants can be measured by selecting electron beam polarizations. (author)

A mini review on CP-violating minimal supersymmetric Standard

Indian Academy of Sciences (India)

We discuss the present status of the Higgs sector of the CP-violating minimal supersymmetric Standard Model (CPVMSSM). In the Standard Model (SM) of particle physics, the only source of CP violation is the complex phase in the Cabibbo–Kobayashi–Maskawa (CKM) matrix. By now we all know that this singlephase is ...

Light Higgs bosons in phenomenological NMSSM

International Nuclear Information System (INIS)

Mahmoudi, F.; Rathsman, J.; Zeune, L.; Goettingen Univ.

2010-12-01

We consider scenarios in the next-to-minimal supersymmetric model (NMSSM) where the CP-odd and charged Higgs bosons are very light. As we demonstrate, these can be obtained as simple deformations of existing phenomenological MSSM benchmarks scenarios with parameters defined at the weak scale. This offers a direct and meaningful comparison to the MSSM case. Applying a wide set of up-to-date constraints from both high-energy collider and flavour physics, the Higgs boson masses and couplings are studied in viable parts of parameter space. The LHC phenomenology of the light Higgs scenario for neutral and charged Higgs boson searches is discussed. (orig.)

Search for neutral MSSM Higgs bosons in the fully hadronic di-tau decay channel with the ATLAS detector

International Nuclear Information System (INIS)

Wahrmund, Sebastian

2017-01-01

The search for additional heavy neutral Higgs bosons predicted in Minimal Supersymmetric Extensions of the Standard Model is presented, using the direct decay channel into two tau leptons which themselves decay hadronically. The study is based on proton-proton collisions recorded in 2011 at a center-of-mass energy of 7 TeV with the ATLAS detector at the Large Hadron Collider at CERN. With a sample size corresponding to an integrated luminosity of 4.5 fb -1 , no significant excess above the expected Standard Model background prediction is observed and CL S exclusion limits at a 95% confidence level are evaluated for values of the CP-odd Higgs boson mass m A between 140 GeV to 800 GeV within the context of the m h max and m h mod± benchmark scenarios. The results are combined with searches for neutral Higgs bosons performed using proton-proton collisions at a center-of-mass energy of 8 TeV recorded with the ATLAS detector in 2012, with a corresponding integrated luminosity of 19.5 fb -1 . The combination allowed an improvement of the exclusion limit at the order of 1 to 3 units in tan β. Within the context of this study, the structure of additional interactions during a single proton-proton collision (the ''underlying event'') in di-jet final states is analyzed using collision data at a center-of-mass energy of 7 TeV recorded with the ATLAS detector in 2010, with a corresponding integrated luminosity of 37 pb -1 . The contribution of the underlying event is measured up to an energy scale of 800 GeV and compared to the predictions of various models. For several models, significant deviations compared to the measurements are found and the results are provided for the optimization of simulation algorithms.

The Flavor of the Composite Pseudo-Goldstone Higgs

CERN Document Server

Csaki, Csaba; Weiler, Andreas

2008-01-01

We study the flavor structure of 5D warped models that provide a dual description of a composite pseudo-Goldstone Higgs. We first carefully re-examine the flavor constraints on the mass scale of new physics in the standard Randall-Sundrum-type scenarios, and find that the KK gluon mass should generically be heavier than about 21 TeV. We then compare the flavor structure of the composite Higgs models to those in the RS model. We find new contributions to flavor violation, which while still are suppressed by the RS-GIM mechanism, will enhance the amplitudes of flavor violations. In particular, there is a kinetic mixing term among the SM fields which (although parametrically not enhanced) will make the flavor bounds even more stringent than in RS, and imply the KK gluon mass to be at least about 33 TeV. For both the RS and the composite Higgs models the flavor bounds could be stronger or weaker depending on the assumption on the value of the gluon boundary kinetic term. These strong bounds seem to imply that the...

Doubling Up on Supersymmetry in the Higgs Sector

CERN Document Server

Ellis, John; Sanz, Verónica

2016-10-17

We explore the possibility that physics at the TeV scale possesses approximate $N = 2$ supersymmetry, which is reduced to the $N=1$ minimal supersymmetric extension of the Standard Model (MSSM) at the electroweak scale. This doubling of supersymmetry modifies the Higgs sector of the theory, with consequences for the masses, mixings and couplings of the MSSM Higgs bosons, whose phenomenological consequences we explore in this paper. The mass of the lightest neutral Higgs boson $h$ is independent of $\\tan \\beta$ at the tree level, and the decoupling limit is realized whatever the values of the heavy Higgs boson masses. Radiative corrections to the top quark and stop squarks dominate over those due to particles in $N=2$ gauge multiplets. We assume that these radiative corrections fix $m_h \\simeq 125$ GeV, whatever the masses of the other neutral Higgs bosons $H, A$, a scenario that we term the $h$2MSSM. Since the $H, A$ bosons decouple from the $W$ and $Z$ bosons in the $h$2MSSM at tree level, only the LHC const...

Higgs versus matter in the heterotic landscape

International Nuclear Information System (INIS)

Buchmueller, W.; Schmidt, J.

2009-01-01

In supersymmetric extensions of the standard model there is no basic difference between Higgs and matter fields, which leads to the well-known problem of potentially large baryon and lepton number violating interactions. Although these unwanted couplings can be forbidden by continuous or discrete global symmetries, a theoretical guiding principle for their choice is missing. We examine this problem for a class of vacua of the heterotic string compactified on an orbifold. As expected, in general there is no difference between Higgs and matter. However, certain vacua happen to possess unbroken matter parity and discrete R-symmetries which single out Higgs fields in the low energy effective field theory. We present a method how to identify maximal vacua in which the perturbative contribution to the μ-term and the expectation value of the superpotential vanish. Two vacua are studied in detail, one with two pairs of Higgs doublets and one with partial gauge-Higgs unification

A direct search for lepton--flavour--violating (LFV) $H\\to\\mu\\tau$ decays of the recently discovered Higgs boson with the ATLAS detector at the LHC is presented. The analysis is performed in the $H\\to\\mu\\tau_{\\mathrm{had}}$ channel, where $\\tau_{\\mathrm{had}}$ is a hadronically decaying $\\tau$--lepton. The search is based on the data sample of proton--proton collisions collected by the ATLAS experiment corresponding to an integrated luminosity of 20.3~fb$^{-1}$ at a centre--of--mass energy of $\\sqrt{s}=8$ TeV. No statistically significant excess of data over the predicted background is observed. The observed (expected) 95% confidence--level upper limit on the branching fraction, Br($H\\to\\mu\\tau$), is 1.85% (1.24%).

CP violation in D0- D-bar0 oscillations: general considerations and applications to the Littlest Higgs model with T-parity

The observed D 0 -D-bar 0 oscillations provide a new stage in our search for New Physics in heavy flavour dynamics. The theoretical verdict on the observed values of x D and y D remains ambiguous: while they could be totally generated by Standard Model dynamics, they could also contain a sizable or even leading contribution from New Physics. Those oscillations are likely to enhance the observability of CP violation as clear manifestations of New Physics. We present general formulae for D 0 - D-bar 0 oscillations, concentrating on the case of negligible direct CP violation. In particular we derive a general formula for the time-dependent mixing-induced CP asymmetry in decays to a CP eigenstate and its correlation with the semileptonic CP asymmetry a SL (D 0 ) in D 0 (t) → lνK. We apply our formalism to the Littlest Higgs model with T-parity, using the time-dependent CP asymmetry in D 0 → K S φ as an example. We find observable effects at a level well beyond anything possible with CKM dynamics. Comparisons with CP violation in the K and B systems offer an excellent test of this scenario and reveal the specific pattern of flavour and CP violation in the D 0 -D-bar 0 system predicted by this model. We discuss a number of charm decays that could potentially offer an insight in the dynamics of CP violation in D decays. We also apply our formalism to B s -B-bar s mixing.

Vector-like fermions are characterized by large neutral current decay rates, in particular into Higgs bosons. If they exist, their clear signals at hadron colliders open a window to Higgs detection, especially to the intermediate Higgs mass region. We discuss in some detail rates and signatures for simple cases. (orig.)

Disentangling Higgs-top couplings in associated production

Ellis, John; Hwang, Dae Sung; Sakurai, Kazuki; Takeuchi, Michihisa

2014-01-01

In the presence of CP violation, the Higgs-top coupling may have both scalar and pseudoscalar components, κ t and κ-tilde t , which are bounded indirectly but only weakly by the present experimental constraints on the Higgs-gluon-gluon and Higgs-γ-γ couplings, whereas upper limits on electric dipole moments provide strong additional indirect constraints on κ-tilde t , if the Higgs-electron coupling is similar to that in the Standard Model and there are no cancellations with other contributions. We discuss methods to measure directly the scalar and pseudoscalar Higgs-top couplings by measurements of Higgs production in association with t-macront, single t and single t-macron at the LHC. Measurements of the total cross sections are very sensitive to variations in the Higgs-top couplings that are consistent with the present indirect constraints, as are invariant mass distributions in t-macrontH, tH and t-macronH final states. We also investigate the additional information on κ t and κ-tilde t that could be obtained from measurements of the longitudinal and transverse t polarization in the different associated production channels, and the t-macront spin correlation in t-macrontH events

Measurement of the light 125 GeV neutral Higgs boson (h0 couplings at the Large Hadron Collider (LHC favor the decoupling limit or the alignment limit of a 2HDM, in which gauge boson and diagonal fermion couplings of h0 approach Standard Model values. In such limit, FCNH couplings of h0 are naturally suppressed by a small mixing parameter cos⁡(β−α, while the off-diagonal couplings of heavier neutral scalars ϕ0 are sustained by sin⁡(β−α∼1. We study physics background from dominant processes with realistic acceptance cuts and tagging efficiencies. Promising results are found for the LHC running at 13 or 14 TeV collision energies.

Associated central exclusive production of charged Higgs bosons

International Nuclear Information System (INIS)

Enberg, Rikard; Pasechnik, Roman

2011-01-01

We propose central exclusive production of a charged Higgs boson in association with a W boson as a possible signature of certain types of extended Higgs sectors. We calculate the cross section and find that the rate at the LHC could be large enough to allow observation in some models with two-Higgs doublets, where the charged Higgs and at least one of the neutral scalars can be light enough. We use the two-Higgs doublet model as a prototype and consider two distinct regions of parameter space, but we also briefly discuss the prospects for the next-to-minimal supersymmetric standard model, where the charged Higgs may very well be quite light.

Search for neutral Higgs bosons in four jets final states with the DELPHI detector; Recherche des bosons de Higgs neutres dans les etats finals a quatre jets avec le detecteur DELPHI

The search for Higgs bosons is one of the priorities of the LEP200 program developed at CERN. Actually, the Higgs mechanism which predicts the existence of scalar bosons of unknown mass, allows the particles of standard model and its supersymmetric extensions to acquire mass. We have carried out a search for neutral Higgs bosons in the two production channels e{sup +}e{sup -} {yields} Z{sup 0*} {yields} h{sup 0}Z{sup 0} and e{sup +}e{sup -} {yields} Z{sup 0*} {yields} h{sup 0}A{sup 0} resulting from the supersymmetric models if only 4 jets final states are taken into account, which represent 65% and 84%, respectively of the possible modes. A special effort has been undertaken towards the reconstruction of the mass of standard Higgs boson (the h{sup 0}Z{sup 0} channel) and on the improvement in the procedure of the event selection. The studies done on the data recorded by DELPHI from 1995 to 1997 ({radical} = 161, 172 and 183 GeV) allowed excluding with the 95% confidence level a standard Higgs boson lighter then: m{sub h{sup 0}} {>=} 84.4 GeV/c{sup 2} at 95% C.L. (observed limit) and m{sub h{sup 0}} {>=} 86.4 GeV/c{sup 2} at 95% C.L. (expected limit), by including the entirety of Z{sup 0} decay modes. An original analysis developed in this thesis has allowed obtaining an expected limit equal to 86.5 GeV/c{sup 2} by using only the 4 jets final state what constitutes a gain of {approx} 3 GeV/c{sup 2} with respect to the limit evaluated so far in DELPHI. The interpretation in the framework of minimal supersymmetric model (MSSM) of the results obtained in the channel h{sup 0}Z{sup 0} and h{sup 0}A{sup 0} have allowed establishing the following limits for the two Higgs neutral bosons h{sup 0} and A{sup 0}: m{sub h{sup 0}} {>=} 74.4 GeV/c{sup 2} at a 95% C.L. for any tan{beta} and m{sub A{sup 0}} {>=} 75.2 GeV/c{sup 2} at 95% C.L. for any tan{beta}, respectively. Finally, a study of the 4 jets events has been done in the frame of an analysis proposed by ALEPH, following

CP properties of symmetry-constrained two-Higgs-doublet models

The two-Higgs-doublet model can be constrained by imposing Higgs-family symmetries and/or generalized CP symmetries. It is known that there are only six independent classes of such symmetry-constrained models. We study the CP properties of all cases in the bilinear formalism. An exact symmetry implies CP conservation. We show that soft breaking of the symmetry can lead to spontaneous CP violation (CPV) in three of the classes.

Prospecting for new physics in the Higgs and flavor sectors

International Nuclear Information System (INIS)

Bishara, Fady

2015-01-01

We explore two directions in beyond the standard model physics: dark matter model building and probing new sources of CP violation. In dark matter model building, we consider two scenarios where the stability of dark matter derives from the flavor symmetries of the standard model. The first model contains a flavor singlet dark matter candidate whose couplings to the visible sector are proportional to the flavor breaking parameters. This leads to a metastable dark matter with TeV scale mediators. In the second model, we consider a fully gauged SU(3) 3 flavor model with a flavor triplet dark matter. Consequently, the dark matter multiplet is charged while the standard model fields are neutral under a remnant Z 3 which ensures dark matter stability. We show that a Dirac fermion dark matter with radiative splitting in the multiplet must have a mass in the range [0:5; 5] TeV in order to satisfy all experimental constraints. We then turn our attention to Higgs portal dark matter and investigate the possibility of obtaining bounds on the up, down, and strange quark Yukawa couplings. If Higgs portal dark matter is discovered, we find that direct detection rates are insensitive to vanishing light quark Yukawa couplings. We then review flavor models and give the expected enhancement or suppression of the Yukawa couplings in those models. Finally, in the last two chapters, we develop techniques for probing CP violation in the Higgs coupling to photons and in rare radiative decays of B mesons. While theoretically clean, we find that these methods are not practical with current and planned detectors. However, these techniques can be useful with a dedicated detector (e.g., a gaseous TPC). In the case of radiative B meson decay B 0 → (K* → Kππ)γ, the techniques we develop also allow the extraction of the photon polarization fraction which is sensitive to new physics contributions since, in the standard model, the right(left) handed polarization fraction is of O(Λ QCD =m b

Quark flavour conserving violations of the lepton number

CERN Document Server

Binétruy, Pierre; Lavignac, Stephane; Savoy, C A

1998-01-01

We study supersymmetric models of lepton and baryon number violation based on an abelian family gauge group. Due to possible lepton-Higgs mixing, the lepton violating couplings are related to the Yukawa couplings and may be generated by them even if they were absent in the original theory. Such terms may be dominant and are not given by the naive family charge counting rules. This enhancement mechanism can provide an alignment between lepton-number violating terms and Yukawa couplings: as a result they conserve quark flavour. A natural way of suppressing baryon number violation in this class of models is also proposed.

A Search for Neutral Supersymmetric Higgs Bosons at DØ

Energy Technology Data Exchange (ETDEWEB)

Osman, Nicolas Ahmed [Imperial College, London (United Kingdom)

2010-09-01

A search for Higgs bosons in multijet data from the DØ detector is reported in this thesis. The Higgs boson is the only remaining undiscovered particle in the Standard Model of particle physics, and plays an integral role in this model. It is known that this model is not a complete description of fundamental physics (it does not describe gravity, for example), and so searches for physics beyond the Standard Model are an important part of particle physics. One extension of the Standard Model, the Minimal Supersymmetric Standard Model (MSSM), predicts the existence of five Higgs bosons, two of which can show an enhanced coupling to bottom quarks. For this reason, a search in the bbb (multijet) channel is a sensitive test of Higgs boson physics. The analysis described in this thesis was conducted over 6.6 fb^-1 of data. At the time of writing, the best limits on tan β (a key parameter of the MSSM) in the multijet channel were set by DØ. The new analysis described in this thesis included more data than the previous analysis in the channel, and made use of a new trigger and event-based analysis method. An improved Multivariate Analysis technique was used to separate signal and background events and produce a final discriminant for the limit setting process. These changes increased the expected sensitivity of this measurement by roughly 50% more than would be expected from the increase in the size of data sample alone.

A search for the lightest neutral CP-even and the neutral CP-odd Higgs bosons of the Minimal Supersymmetric Standard Model is performed using 233.2 pb-1 of integrated luminosity collected with the L3 detector at LEP at centre-of-mass energies 192-202 GeV. No signal is observed and lower mass limits are given as a function of tan(beta) for two scalar top mixing hypotheses. For tan(beta) greater than 0.8, they are mh > 83.4 GeV and mA > 83.8 GeV at 95 % confidence level.

Phenomenology of the spontaneous C P violation in SU(3)L x U(1)Y electroweak models

This work studies the phenomenological consequence of the spontaneous C P violation in a SU(3) L x U(1) Y model with three Higgs triplets and one sextuplet, which has been recently proposed. Since this C P-violating effects are due to the presence of complex vacuum expectation values in the Higgs sector, our analysis requires a detailed study of the enlarged potential

Recently, the possibility of quantum simulation of dynamical gauge fields was pointed out by using a system of cold atoms trapped on each link in an optical lattice. However, to implement exact local gauge invariance, fine-tuning the interaction parameters among atoms is necessary. In the present Letter, we study the effect of violation of the U(1) local gauge invariance by relaxing the fine-tuning of the parameters and showing that a wide variety of cold atoms is still a faithful quantum simulator for a U(1) gauge-Higgs model containing a Higgs field sitting on sites. The clarification of the dynamics of this gauge-Higgs model sheds some light upon various unsolved problems, including the inflation process of the early Universe. We study the phase structure of this model by Monte Carlo simulation and also discuss the atomic characteristics of the Higgs phase in each simulator.

Studies of b-associated production and muonic decays of neutral Higgs bosons at the ATLAS experiment within the Minimal Supersymmetric Standard Model

2008-01-01

This thesis presents a Monte Carlo study of neutral Higgs bosons of the Minimal Supersymmetric Standard Model (MSSM) decaying into muons at the ATLAS experiment at the CERN Large Hadron Collider. Signal and background processes are simulated using novel Monte Carlo generators that incorporate parts of higher order corrections and are expected to give a more accurate prediction than previous programs. The SHERPA Monte Carlo generator is validated for its use in the analysis and compared to results obtained with other programs. Where possible, the Monte Carlo event samples are normalized to higher order calculations. To increase the available Monte Carlo statistics, this study is based on the ATLAS fast detector simulation ATLFAST. Differences between ATLFAST and the detailed detector simulation of ATLAS are examined, and, where possible, correction procedures are devised. A cut based analysis is performed assuming an integrated luminosity of 30 fb -1 , and optimized with respect to the discovery potential for MSSM Higgs bosons. The systematic uncertainties of the event selection and the Monte Carlo predictions are estimated. A method that can be used to estimate the background from data is presented and evaluated. Last, the discovery potential of the ATLAS experiment in the CP conserving benchmark scenarios of the MSSM is evaluated. One or more of the neutral Higgs bosons of the MSSM can be discovered in the muonic decay mode using 30 fb -1 of data for low masses of the pseudoscalar boson A 0 , if the model parameter tan β is at least 20. For higher masses of the A 0 , tan β would need to be significantly higher to ensure a discovery in the studied decay channel. The sensitivity of ATLAS to MSSM Higgs bosons is multiple times larger than the one of previous and currently running experiments. (orig.)

2015-01-01

Some recent searches for the Higgs boson in the context of beyond the Standard Model, performed by the ATLAS experiment are presented: high mass Higgs boson searches, lepton flavour violating Higgs decay, NMSSM, con- straint from the search for three photons. The interpretation based on the measurements of Higgs couplings are shown, along with the constraint on the Higgs boson invisible decays. Except the latter has some part using both full √s = 7 TeV and √s = 8 TeV data, the rest are performed with the √s = 8 TeV data of proton-proton collisions collected by the ATLAS experiment. No sig- nificant excess of data over the predicted background is observed in all those searches. Limits are placed in certain quantities depending on the searches.

In the presence of CP violation, the Higgs-top coupling may have both scalar and pseudoscalar components, κ{sub t} and κ-tilde{sub t}, which are bounded indirectly but only weakly by the present experimental constraints on the Higgs-gluon-gluon and Higgs-γ-γ couplings, whereas upper limits on electric dipole moments provide strong additional indirect constraints on κ-tilde{sub t}, if the Higgs-electron coupling is similar to that in the Standard Model and there are no cancellations with other contributions. We discuss methods to measure directly the scalar and pseudoscalar Higgs-top couplings by measurements of Higgs production in association with t-macront, single t and single t-macron at the LHC. Measurements of the total cross sections are very sensitive to variations in the Higgs-top couplings that are consistent with the present indirect constraints, as are invariant mass distributions in t-macrontH, tH and t-macronH final states. We also investigate the additional information on κ{sub t} and κ-tilde{sub t} that could be obtained from measurements of the longitudinal and transverse t polarization in the different associated production channels, and the t-macront spin correlation in t-macrontH events.

Search for MSSM Higgs Bosons in Tau Final States with the D0 Detector

2010-01-01

The cross-section times branching ratio of the Higgs boson decaying to τ + τ - final state in the Standard Model (SM) is too small to play any role in the SM Higgs boson searches. This, however, is different in the Minimal Supersymmetric Standard Model (MSSM), which predicts two Higgs doublets leading to five Higgs bosons: a pair of charged Higgs boson (H ± ); two neutral CP-even Higgs bosons (h,H) and a CP-odd Higgs boson (A). A search for the production of neutral Higgs bosons decaying into τ + τ - final states in p(bar p) collisions at a centre-of-mass energy of √s = 1.96 TeV is presented in this thesis. One of the two τ leptons is required to decay into a muon while the other decays hadronically. The integrated luminosity is L = 1.0-5.36 fb -1 , collected by the D0 experiment at the Fermilab Tevatron Collider from 2002 to 2009 in the Run II.

Multi-Higgs doublet models: physical parametrization, sum rules and unitarity bounds

If the scalar sector of the Standard Model is non-minimal, one might expect multiple generations of the hypercharge-1/2 scalar doublet analogous to the generational structure of the fermions. In this work, we examine the structure of a Higgs sector consisting of N Higgs doublets (where N ≥ 2). It is particularly convenient to work in the so-called charged Higgs basis, in which the neutral Higgs vacuum expectation value resides entirely in the first Higgs doublet, and the charged components of remaining N - 1 Higgs doublets are mass-eigenstate fields. We elucidate the interactions of the gauge bosons with the physical Higgs scalars and the Goldstone bosons and show that they are determined by an N × 2 N matrix. This matrix depends on ( N - 1)(2 N - 1) real parameters that are associated with the mixing of the neutral Higgs fields in the charged Higgs basis. Among these parameters, N - 1 are unphysical (and can be removed by rephasing the physical charged Higgs fields), and the remaining 2( N - 1)2 parameters are physical. We also demonstrate a particularly simple form for the cubic interaction and some of the quartic interactions of the Goldstone bosons with the physical Higgs scalars. These results are applied in the derivation of Higgs coupling sum rules and tree-level unitarity bounds that restrict the size of the quartic scalar couplings. In particular, new applications to three Higgs doublet models with an order-4 CP symmetry and with a Z_3 symmetry, respectively, are presented.

CP Violation course

CERN. Geneva HR-RFA

2006-01-01

The lecture introduces the concepts and phenomena of matter-antimatter symmetry violation, so-called "CP" violation. The lecture is organized in four courses, the first being devoted to a historical overview and an introduction into fundamental discrete symmetries. The second course introduces the most compelling CP-violating phenomena, and presents the first experimental discovery of CP violation in the neutral kaon system. The third course discusses how CP violation is beautifully incorporated into the Standard Model of particle interactions, and how modern B-meson "factories" provide precise tests of this picture. Finally, the fourth and last course introduces CP violation and the genesis of our matter world.

We study the potential of future lepton colliders to probe violation of the CP symmetry in the top quark sector. In certain extensions of the Standard Model, such as the two-Higgs-doublet model (2HDM), sizeable anomalous top quark dipole moments can arise, which may be revealed by a precise measurement of top quark pair production. We present results from detailed Monte Carlo studies for the ILC at 500 GeV and CLIC at 380 GeV and use parton-level simulations to explore the potential of high-energy operation. We find that precise measurements in e{sup +}e{sup -} → t anti t production with subsequent decay to lepton plus jets final states can provide sufficient sensitivity to detect Higgs-boson-induced CP violation in a viable two-Higgs-doublet model. The potential of a linear e{sup +}e{sup -} collider to detect CP-violating electric and weak dipole form factors of the top quark exceeds the prospects of the HL-LHC by over an order of magnitude.

A search is performed for Higgs-boson-mediated flavor-changing neutral currents in the decays of top quarks. The search is based on proton-proton collision data corresponding to an integrated luminosity of 19.7 fb$^{-1}$ at a center-of-mass energy of 8 TeV collected with the CMS detector at the LHC. Events in which a top quark pair is produced with one top quark decaying into a charm or up quark and a Higgs boson (H), and the other top quark decaying into a bottom quark and a W boson are selected. The Higgs boson in these events is assumed to subsequently decay into either dibosons or difermions. No significant excess is observed above the expected standard model background, and an upper limit at the 95\\% confidence level is set on the branching fraction $\\mathcal{B} ({\\rm t \\to Hc} )$ of 0.40\\% and $\\mathcal{B}({\\rm t \\to Hu})$ of 0.55\\%, where the expected upper limits are 0.43\\% and 0.40\\%, respectively.

Structure of potentials with N Higgs doublets

International Nuclear Information System (INIS)

Nishi, C. C.

2007-01-01

Extensions of the standard model with N Higgs doublets are simple extensions presenting a rich mathematical structure. An underlying Minkowski structure emerges from the study of both variable space and parameter space. The former can be completely parametrized in terms of two future lightlike Minkowski vectors with spatial parts forming an angle whose cosine is -(N-1) -1 . For the parameter space, the Minkowski parametrization enables one to impose sufficient conditions for bounded below potentials, characterize certain classes of local minima, and distinguish charge breaking vacua from neutral vacua. A particular class of neutral minima presents a degenerate mass spectrum for the physical charged Higgs bosons

Right-handed quark mixings in minimal left-right symmetric model with general CP violation

Zhang Yue; Ji Xiangdong; An Haipeng; Mohapatra, R. N.

2007-01-01

We solve systematically for the right-handed quark mixings in the minimal left-right symmetric model which generally has both explicit and spontaneous CP violations. The leading-order result has the same hierarchical structure as the left-handed Cabibbo-Kobayashi-Maskawa mixing, but with additional CP phases originating from a spontaneous CP-violating phase in the Higgs vacuum expectation values. We explore the phenomenology entailed by the new right-handed mixing matrix, particularly the bounds on the mass of W R and the CP phase of the Higgs vacuum expectation values

Search for neutral MSSM Higgs bosons in the fully hadronic di-tau decay channel with the ATLAS detector

Energy Technology Data Exchange (ETDEWEB)

Wahrmund, Sebastian

2017-06-23

The search for additional heavy neutral Higgs bosons predicted in Minimal Supersymmetric Extensions of the Standard Model is presented, using the direct decay channel into two tau leptons which themselves decay hadronically. The study is based on proton-proton collisions recorded in 2011 at a center-of-mass energy of 7 TeV with the ATLAS detector at the Large Hadron Collider at CERN. With a sample size corresponding to an integrated luminosity of 4.5 fb{sup -1}, no significant excess above the expected Standard Model background prediction is observed and CL{sub S} exclusion limits at a 95% confidence level are evaluated for values of the CP-odd Higgs boson mass m{sub A} between 140 GeV to 800 GeV within the context of the m{sub h}{sup max} and m{sub h}{sup mod±} benchmark scenarios. The results are combined with searches for neutral Higgs bosons performed using proton-proton collisions at a center-of-mass energy of 8 TeV recorded with the ATLAS detector in 2012, with a corresponding integrated luminosity of 19.5 fb{sup -1}. The combination allowed an improvement of the exclusion limit at the order of 1 to 3 units in tan β. Within the context of this study, the structure of additional interactions during a single proton-proton collision (the ''underlying event'') in di-jet final states is analyzed using collision data at a center-of-mass energy of 7 TeV recorded with the ATLAS detector in 2010, with a corresponding integrated luminosity of 37 pb{sup -1}. The contribution of the underlying event is measured up to an energy scale of 800 GeV and compared to the predictions of various models. For several models, significant deviations compared to the measurements are found and the results are provided for the optimization of simulation algorithms.

Search for top quark decays via Higgs-boson-mediated flavor-changing neutral currents in pp collisions at √s=8 TeV

Collaboration: The CMS collaboration

2017-02-15

A search is performed for Higgs-boson-mediated flavor-changing neutral currents in the decays of top quarks. The search is based on proton-proton collision data corresponding to an integrated luminosity of 19.7 fb{sup −1} at a center-of-mass energy of 8 TeV collected with the CMS detector at the LHC. Events in which a top quark pair is produced with one top quark decaying into a charm or up quark and a Higgs boson (H), and the other top quark decaying into a bottom quark and a W boson are selected. The Higgs boson in these events is assumed to subsequently decay into either dibosons or difermions. No significant excess is observed above the expected standard model background, and an upper limit at the 95% confidence level is set on the branching fraction B(t→Hc) of 0.40% and B(t→Hu) of 0.55%, where the expected upper limits are 0.43% and 0.40%, respectively. These results correspond to upper limits on the square of the flavor-changing Higgs boson Yukawa couplings |λ{sub tc}{sup H}|{sup 2}<6.9×10{sup −3} and |λ{sub tu}{sup H}|{sup 2}<9.8×10{sup −3}.

Ruling out Critical Higgs Inflation? arXiv

CERN Document Server

Masina, Isabella

We consider critical Higgs inflation, namely Higgs inflation with a rising inflection point at smaller field values than those of the plateau induced by the non-minimal coupling to gravity. It has been proposed that such configuration is compatible with the present CMB observational constraints on inflation, and also with primordial black hole production accounting for the totality or a fraction of the observed dark matter. We study the model taking into account the NNLO corrections to the Higgs effective potential: such corrections are extremely important to reduce the theoretical error associated to the calculation. We find that, in the 3 sigma window for the relevant low energy parameters, which are the strong coupling and the Higgs mass (the top mass follows by requiring an inflection point), the potential at the inflection point is so large (and so is the Hubble constant during inflation) that the present bound on the tensor-to-scalar ratio is violated. The model is viable only allowing the strong coupli...

Search strategies for Higgs Bosons at high energy e+e/sup /minus// colliders

International Nuclear Information System (INIS)

1989-01-01

We have used detailed Monte Carlo simulations to study search strategies for Higgs bosons at high energy e + e/sup /minus// colliders. We extend an earlier study of the minimal single-Higgs-doublet model at a center-of-mass energy of 1 TeV to examine the effects of b-quark tagging and jet counting. It is found that these techniques can increase the signal-to-noise ratio substantially in the mass range around the W mass. In addition, we have studied this model at a center-of-mass energy of 400 GeV and found that an e + e/sup /minus// collider in this region would be sensitive to a Higgs boson with mass up to twice the Z/degree/ mass. We have also considered a nonminimal two-doublet model for the Higgs sector by extending a study of charged Higgs boson searches to include a mass very close to the mass of the W/sup +-/. We demonstrate that techniques which include b-quark tagging can be utilized to extract a significant signal. In addition, we have examined the prospects for detecting nonminimal neutral Higgs bosons at 1 TeV. We conclude that it would be possible to detect the CP-even and CP-odd neutral Higgs bosons when they are pair-produced in e + e/sup /minus// annihilation over a limited mass range. However, in some scenarios of supersymmetry, the charged Higgs boson constitutes a significant background to the CP-odd and the more massive CP-even neutral Higgs boson. 16 refs., 13 figs., 2 tabs

In the first two lectures, CP violation in the K system is pedagogically reviewed: its manifestations in the neutral K meson systems, in rare K meson decays and in decays of charged K mesons, and results from classical and current experiments, are discussed. In the third lecture, CP Violation in the B system and the forthcoming experimental tests will be discussed.

W, Z, Higgs, and their production in hadron collisions: perspectives

International Nuclear Information System (INIS)

Savoy, C.A.

1980-01-01

The disintegration of intermediate vector bosons (Z 0 , W +- ) is first studied: branching ratios, angular distributions, assymmetries. Then we discuss the production of W's and Z and the possibilities to detect some specific final states in antipp collisions, within the energy range foreseen for the machines currently being built. The effects of 'scaling' violation and of radiative corrections in the frame of Q.C.D. are stressed. The second part deals with the production of Higgs bosons in pp and antipp collisions. We consider several possibilities: the associated production of Higgs boson with Z 0 , the coupling of Higgs boson to gluons in the case of very heavy fermions and the possibility of mixing of Higgs with bound states of heavy quarks. In all cases the cross section for Higgs productions are found very small in pp or antipp collisions [fr

Higgs particles can be radiated off heavy top quarks which will be produced copiously in high energy e + e - colliders. This process can be used to measure the Higgs-top quark coupling. We present the cross section for the production of Higgs bosons in the Standard Model. In addition we have studied the production of neutral and charged Higgs particles in association with heavy fermions in the Minimal Supersymmetric Standard Model. (orig.)

Testing New Indirect CP Violation

International Nuclear Information System (INIS)

Grossman, Yuval; Nir, Yosef; Perez, Gilad

2009-01-01

If new CP violating physics contributes to neutral meson mixing, but its contribution to CP violation in decay amplitudes is negligible, then there is a model independent relation between four (generally independent) observables related to the mixing: the mass splitting (x), the width splitting (y), the CP violation in mixing (1-|q/p|), and the CP violation in the interference of decays with and without mixing (φ). For the four neutral meson systems, this relation can be written in a simple approximate form: ytanφ≅x(1-|q/p|). In the K system, all four observables have been measured and obey the relation to excellent accuracy. For the B s and D systems, new predictions are provided. The success or failure of these relations will probe the physics that is responsible for the CP violation.

We present a search for neutral supersymmetric Higgs bosons decaying to tau pairs produced in pp collisions at square root of s = 1.96 TeV. The data, corresponding to 310 pb(-1) integrated luminosity, were collected with the Collider Detector at Fermilab in run II of the Tevatron. No significant excess above the standard model backgrounds is observed. We set exclusion limits on the production cross section times branching fraction to tau pairs for Higgs boson masses in the range from 90 to 250 GeV/c2.

Gauge boson/Higgs boson unification: The Higgs bosons as superpartners of massive gauge bosons

International Nuclear Information System (INIS)

Fayet, P.

1984-01-01

We show how one can use massive gauge superfields to describe, simultaneously, gauge bosons (Wsup(+-), Z, ...) and Higgs bosons (wsup(+-), z, ...) together with their spin-1/2 partners (pairs of winos, zinos, ...), despite their different electroweak properties. This provides a manifestly supersymmetric formulation of spontaneously broken supersymmetric gauge theories, and makes explicit the relations between massive gauge bosons and Higgs bosons. It raises, however, the following question: if the gauge bosons Wsup(+-) and Z and the Higgs bosons wsup(+-) and z are related by supersymmetry, how it is possible that the former couple to leptons and quarks proportionately to g or g', and the latter proportionately to gsub(F)sup(1/2) m (fermions). The paradox is solved as follows: when the Higgs bosons are described by massive gauge superfields, the lagrangian density is non-polynomial and field redefinitions have to be performed, in particular: lepton or quark field -> lepton or quark field + (approx.= Gsub(F)sup(1/2) Higgs field) (lepton or quark field). They automatically regenerate, from the lepton and quark supersymmetric mass terms, the correct Yukawa couplings of Higgs bosons proportional to fermion masses. We also apply this method to the case in which an extra U(1) group is gauged, the standard Higgs boson h 0 being then the superpartner of the new neutral gauge boson U. (orig.)

A Search for Neutral Supersymmetric Higgs Bosons at D0

International Nuclear Information System (INIS)

Osman, Nicolas Ahmed

2010-01-01

A search for Higgs bosons in multijet data from the D0 detector is reported in this thesis. The Higgs boson is the only remaining undiscovered particle in the Standard Model of particle physics, and plays an integral role in this model. It is known that this model is not a complete description of fundamental physics (it does not describe gravity, for example), and so searches for physics beyond the Standard Model are an important part of particle physics. One extension of the Standard Model, the Minimal Supersymmetric Standard Model (MSSM), predicts the existence of five Higgs bosons, two of which can show an enhanced coupling to bottom quarks. For this reason, a search in the bbb (multijet) channel is a sensitive test of Higgs boson physics. The analysis described in this thesis was conducted over 6.6 fb -1 of data. At the time of writing, the best limits on tan β (a key parameter of the MSSM) in the multijet channel were set by D0. The new analysis described in this thesis included more data than the previous analysis in the channel, and made use of a new trigger and event-based analysis method. An improved Multivariate Analysis technique was used to separate signal and background events and produce a final discriminant for the limit setting process. These changes increased the expected sensitivity of this measurement by roughly 50% more than would be expected from the increase in the size of data sample alone.

Search for MSSM Higgs Bosons in Tau Final States with the D0 Detector

2010-01-01

The cross-section times branching ratio of the Higgs boson decaying to τ⁺τ^- final state in the Standard Model (SM) is too small to play any role in the SM Higgs boson searches. This, however, is different in the Minimal Supersymmetric Standard Model (MSSM), which predicts two Higgs doublets leading to five Higgs bosons: a pair of charged Higgs boson (H^±); two neutral CP-even Higgs bosons (h,H) and a CP-odd Higgs boson (A). A search for the production of neutral Higgs bosons decaying into τ⁺τ^- final states in p{bar p} collisions at a centre-of-mass energy of √s = 1.96 TeV is presented in this thesis. One of the two τ leptons is required to decay into a muon while the other decays hadronically. The integrated luminosity is L = 1.0-5.36 fb ^-1, collected by the D0 experiment at the Fermilab Tevatron Collider from 2002 to 2009 in the Run II.

Higgs bosons in the left-right model

2000-01-01

The model with the SU(2) L x SU(2) R x U(1) B-L gauge group, containing one bidoublet and two triplets in the Higgs sector, is considered. The link between the constants determining the physical Higgs boson interactions and the neutrino oscillation parameters is found. It is shown that the observation of the ultrahigh-energy neutrinos with the help of the processes e - ν e →W - Z, e - ν e →μ - ν μ , gives us information on the singly charged Higgs bosons. The processes of the doubly charged Higgs boson production, e - μ - →Δ (--) 1 γ, e - μ - →Δ (--) 1 Z, are investigated. From the point of view of detecting the neutral Higgs bosons the process of the electron-muon recharge e - μ + →e + μ - is studied. (orig.)

Flavour physics and CP violation

Nir, Y.

2015-05-22

We explain the many reasons for the interest in flavor physics. We describe flavor physics and the related CP violation within the Standard Model, and explain how the B-factories proved that the Kobayashi-Maskawa mechanism dominates the CP violation that is observed in meson decays. We explain the implications of flavor physics for new physics, with emphasis on the “new physics flavor puzzle”, and present the idea of minimal flavor violation as a possible solution. We explain why the values flavor parameters of the Standard Model are puzzling, present the Froggatt-Nielsen mechanism as a possible solution, and describe how measurements of neutrino parameters are interpreted in the context of this puzzle. We show that the recently discovered Higgs-like boson may provide new opportunities for making progress on the various flavor puzzles.

CP violation through particle mixing and the H-A lineshape

International Nuclear Information System (INIS)

Bernabeu, Jose; Binosi, Daniele; Papavassiliou, Joannis

2006-01-01

We consider the possibility of looking for CP-mixing effects in two-Higgs doublet models (and particularly in the MSSM) by studying the lineshape of the CP-even (H) and CP-odd (A) neutral scalars. In most cases H and A come quite degenerate in mass, and their s-channel production would lead to nearly overlapping resonances. CP-violating effects may connect these two Higgs bosons, giving origin to one-loop particle mixing, which, due to their mass proximity, can be resonantly enhanced. The corresponding transition amplitude contains then CP-even and CP-odd components; besides the signal of intereference between both amplitudes, leading to a CP-odd asymmetry, we propose to look for the mixing probability itself, a quantity which, although CP-even, can originate only from a CP-odd amplitude. We show that, in general, the effect of such a mixing probability cannot be mimicked by (or be re-absorbed into) a simple redefinition of the H and A masses in the context of a CP-conserving model. Specifically, the effects of the CP-mixing are such that, either the mass-splitting of the H and A bosons cannot be accounted for in the absence of CP-mixing, and/or the detailed energy dependence of the produced lineshape is clearly different from the one obtained by redefining the masses, but not allowing any mixing. This analysis suggests that the detailed study of the lineshape of this Higgs system may provide valuable information on the CP nature of the underlying theory

Search for neutral MSSM Higgs bosons in association with b quarks in the tau-tau decay channels at CDF Run II

Cox, Charles A. [Univ. of California, Davis, CA (United States)

2013-01-01

This thesis presents the results of a search for neutral MSSM Higgs bosons decaying to ττ with 5.9 fb.^–1 of data. The analysis requires at least one of the taus to decay leptonically, and explores three detection modes in two channels: τeτ _μ, τeτ_had, and τμτ_had, where the index denotes the type of tau decay. In all modes we explore the tagged and untagged channel. No signal is observed limits were set on σ( p$\\bar{p}$ → Φ + X) × BR(Φ → ττ) as a function of Higgs mass. The results are also interpreted as exclusions of parameter space in the tanβ vs m_A plane for several benchmark scenarios.

Higgs-Boson Two-Loop Contributions to Electric Dipole Moments in the MSSM

Pilaftsis, Apostolos

1999-01-01

The complete set of Higgs-boson two-loop contributions to electric dipole moments of the electron and neutron is calculated in the minimal supersymmetric standard model. The electric dipole moments are induced by CP-violating trilinear couplings of the `CP-odd' and charged Higgs bosons to the scalar top and bottom quarks. Numerical estimates of the individual two-loop contributions to electric dipole moments are given.

Higgs Pair Production as a Signal of Enhanced Yukawa Couplings

Energy Technology Data Exchange (ETDEWEB)

Bauer, Martin [Heidelberg U.; Carena, Marcela [Chicago U., KICP; Carmona, Adrián [U. Mainz, PRISMA

2017-12-31

We present a non-trivial correlation between the enhancement of the Higgs-fermion couplings and the Higgs pair production cross section in two Higgs doublet models with a flavour symmetry. This symmetry suppresses flavour-changing neutral couplings of the Higgs boson and allows for a partial explanation of the hierarchy in the Yukawa sector. After taking into account the constraints from electroweak precision measurements, Higgs coupling strength measurements, and unitarity and perturbativity bounds, we identify an interesting region of parameter space leading to enhanced Yukawa couplings as well as enhanced di-Higgs gluon fusion production at the LHC reach. This effect is visible in both the resonant and non-resonant contributions to the Higgs pair production cross section. We encourage dedicated searches based on differential distributions as a novel way to indirectly probe enhanced Higgs couplings to light fermions.

Search for hidden Higgs decay in ATLAS detector

Gabrielli, A.

2013-01-01

In this paper, a brief overview of the search for the Higgs boson in Hidden Valley models is given. Hidden Valley models predict Higgs decays to neutral particles, which can be also long lived with decay paths comparable to the LHC detectors dimensions. Decay final states consist of collimated leptons (Lepton Jets). Results are presented of a search for Higgs decays to long lived particles in the ATLAS detector at the LHC, based on 1.92 fb −1 data collected during 2011 at a 7TeV center-of-mass energy.

Prospecting for new physics in the Higgs and flavor sectors

Bishara, Fady [Univ. of Cincinnati, OH (United States)

We explore two directions in beyond the standard model physics: dark matter model building and probing new sources of CP violation. In dark matter model building, we consider two scenarios where the stability of dark matter derives from the flavor symmetries of the standard model. The first model contains a flavor singlet dark matter candidate whose couplings to the visible sector are proportional to the flavor breaking parameters. This leads to a metastable dark matter with TeV scale mediators. In the second model, we consider a fully gauged SU(3)³ flavor model with a flavor triplet dark matter. Consequently, the dark matter multiplet is charged while the standard model fields are neutral under a remnant Z₃ which ensures dark matter stability. We show that a Dirac fermion dark matter with radiative splitting in the multiplet must have a mass in the range [0:5; 5] TeV in order to satisfy all experimental constraints. We then turn our attention to Higgs portal dark matter and investigate the possibility of obtaining bounds on the up, down, and strange quark Yukawa couplings. If Higgs portal dark matter is discovered, we find that direct detection rates are insensitive to vanishing light quark Yukawa couplings. We then review flavor models and give the expected enhancement or suppression of the Yukawa couplings in those models. Finally, in the last two chapters, we develop techniques for probing CP violation in the Higgs coupling to photons and in rare radiative decays of B mesons. While theoretically clean, we find that these methods are not practical with current and planned detectors. However, these techniques can be useful with a dedicated detector (e.g., a gaseous TPC). In the case of radiative B meson decay B⁰ → (K* → Kππ) γ, the techniques we develop also allow the extraction of the photon polarization fraction which is sensitive to new physics contributions since, in the standard model, the right(left) handed

CP determination and tests for CP or P violation by the V1V2 decay mode

International Nuclear Information System (INIS)

Nelson, C.A.

1984-01-01

A decay mode such as phiphi, UPSILONUPSILON, K/sup asterisk+/K/sup asterisk-/, or D/sup asterisk+/D/sup asterisk-/ can be used to distinguish between a neutral spin-0 technipion and a neutral spin-0 Higgs particle. By this generalization of phiphi parity test, the CP eigenvalue γ/sub C/P can be determined for an X particle of any spin J which decays CP invariantly into VV, or VV-bar, where each vector meson either decays into two spin-0 bosons, or is ω. The absence in a VV, or VV-bar, decay channel of sin2phi and sinphi terms in the azimuthal distribution is due to CP invariance and/or P invariance. For a V 1 V 2 decay channel without a V 1 bold-arrow-left-rightV 2 exchange property, and in a mode like K/sup asterisk+/K /sup asterisk0/, such terms would imply that P is violated. For a V 1 V 2 mode such as phiω where each vector meson is its own antiparticle, such terms would imply that both P and CP are violated; when CP invariance holds, the γ/sub C/P(-)/sup J/ eigenvalue of X can be determined provided certain amplitudes do not accidentally vanish

B-meson anomalies and Higgs physics in flavored U(1)' model

Science.gov (United States)

Bian, Ligong; Lee, Hyun Min; Park, Chan Beom

2018-04-01

We consider a simple extension of the Standard Model with flavor-dependent U(1)', that has been proposed to explain some of B-meson anomalies recently reported at LHCb. The U(1)' charge is chosen as a linear combination of anomaly-free B_3-L_3 and L_μ -L_τ . In this model, the flavor structure in the SM is restricted due to flavor-dependent U(1)' charges, in particular, quark mixings are induced by a small vacuum expectation value of the extra Higgs doublet. As a result, it is natural to get sizable flavor-violating Yukawa couplings of heavy Higgs bosons involving the bottom quark. In this article, we focus on the phenomenology of the Higgs sector of the model including extra Higgs doublet and singlet scalars. We impose various bounds on the extended Higgs sector from Higgs and electroweak precision data, B-meson mixings and decays as well as unitarity and stability bounds, then discuss the productions and decays of heavy Higgs bosons at the LHC.

Search for Higgs bosons of the minimal supersymmetric standard model in p(bar p) collisions at √s = 1.96 TeV

International Nuclear Information System (INIS)

2012-01-01

We report results from searches for neutral Higgs bosons produced in p(bar p) collisions recorded by the D0 experiment at the Fermilab Tevatron Collider. We study the production of inclusive neutral Higgs boson in the ττ final state and in association with a b quark in the bττ and bbb final states. These results are combined to improve the sensitivity to the production of neutral Higgs bosons in the context of the minimal supersymmetric standard model (MSSM). The data are found to be consistent with expectation from background processes. Upper limits on MSSM Higgs boson production are set for Higgs boson masses ranging from 90 to 300 GeV. We exclude tan β > 20-30 for Higgs boson masses below 180 GeV. These are the most stringent constraints on MSSM Higgs boson production in p(bar p) collisions.

The discovery of a Higgs boson at the LHC was a great success. However supersymmetric extensions of the Standard Model predict more than one Higgs boson. The NMSSM Higgs sector contains seven Higgs bosons, of which the three lightest are neutral and CP even. This allows for a via gluon-gluon fusion produced heavy H{sub 3} to decay into the SM-like H{sub 2} and an even lighter H{sub 1}. These then decay into two tau leptons and two b quarks, respectively. Private results and exclusion limits of this analysis are presented.

A search for the decays of the neutral Higgs bosons A, h, and H of the minimal supersymmetric extension of the Standard Model (MSSM) into tau lepton pairs with subsequent decay via τ + τ - to electron and muon+4 neutrino has been performed using proton-proton collision data recorded by the ATLAS experiment at the Large Hadron Collider (LCH) at a center-of-mass energy of 8 TeV which correspond to an integrated luminosity of 20.3 fb -1 . No significant excess over the Standard Model background has been observed. Exclusion limits for the MSSM mh-mod scenario have been derived depending on the mass m A of the A boson and on the ratio tan(beta) of the vacuum expectation values of the two MSSM Higgs dublets.

We perform a detailed study of the exclusive Higgs decays h→MZ and h→MW, where M is a pseudoscalar or vector meson, using the QCD factorization approach. We allow for the presence of new-physics effects in the form of modified Higgs couplings to gauge bosons and fermions, including the possibility of flavor-changing Higgs couplings. We show that the decays h→VZ exhibit a strong sensitivity to the effective CP-even and CP-odd hγZ couplings. When combined with a measurement of the h→γZ decay rate, this can be used to extract these couplings up to a sign ambiguity in the CP-odd coefficient. Some of the h→MW decay modes can be used to probe for flavor-violating Higgs couplings involving the top quark.

Parity violation in electron scattering; Violation de parite en diffusion d'electrons

Lhuillier, D

2007-09-15

The elaboration of the electroweak standard model from the discovery of parity violation to the weak neutral current is described in the first chapter. In the second chapter the author discusses the 2 experimental approaches of the parity violation experiments. In the first approach the weak neutral current can be assumed to be well known and can be used as a probe for the hadronic matter. The second approach consists in measuring the weak neutral current between 2 particles with known internal structure in order to test the predictions of the standard model in the low energy range. The chapters 3 and 4 are an illustration of the first approach through the HAPPEx series of experiments that took place in the Jefferson Laboratory from 1998 to 2005. The HAPPEx experiments aimed at measuring the contribution of strange quarks in the electromagnetic form factors of the nucleon through the violation of parity in the elastic scattering at forward angles. The last chapter is dedicated to the E158 experiment that was performed at the Slac (California) between 2000 and 2003. The weak neutral current was measured between 2 electrons and the high accuracy obtained allowed the physics beyond the standard model to be indirectly constraint up to a few TeV. (A.C.)

Direct search for Higgs boson in LHCb

Currat, C

2001-01-01

The LHCb detector is a forward one-arm spectrometer to precision measurements of CP violation in the B-meson systems. The motivation of the present work is to assess the potential of LHCb to observe a Standard Model (SM) Higgs signal. The recent results obtained at LEP give a hint of a SM Higgs boson with a mass mH = 115.0 +1.3 –0.9 GeV/c2 with a statistical significance of 2.9 standard deviations. Because of the high longitudinal boost encountered by the products in the pp collisions at LHC, a significant fraction (~30%) of light Higgs (mH = 115 GeV/c2) are produced in the LHCb acceptance 1.8 < h < 4.9. These facts potentially place LHCb in the race for the observation of the SM Higgs. Given a relatively low running luminosity of 2 x 1032 cm-2s-1- compared to the nominal 1034 cm-2s-1 at LHC and a limited geometrical acceptance, we have shown that the channels accessible to LHCb are H + W± Z0 b`b + l± X for Higgs masses in the range 100-130 GeV/c2.

We describe the new developments in version 4 of the public computer code HiggsBounds. HiggsBounds is a tool to test models with arbitrary Higgs sectors, containing both neutral and charged Higgs bosons, against the published exclusion bounds from Higgs searches at the LEP, Tevatron and LHC experiments. From the model predictions for the Higgs masses, branching ratios, production cross sections and total decay widths - which are specified by the user in the input for the program - the code calculates the predicted signal rates for the search channels considered in the experimental data. The signal rates are compared to the expected and observed cross section limits from the Higgs searches to determine whether a point in the model parameter space is excluded at 95% confidence level. In this paper we present a modification of the HiggsBounds main algorithm that extends the exclusion test in order to ensure that it provides useful results in the presence of one or more significant excesses in the data, corresponding to potential Higgs signals. We also describe a new method to test whether the limits from an experimental search performed under certain model assumptions can be applied to a different theoretical model. Further developments discussed here include a framework to take into account theoretical uncertainties on the Higgs mass predictions, and the possibility to obtain the {chi}{sup 2} likelihood of Higgs exclusion limits from LEP. Extensions to the user subroutines from earlier versions of HiggsBounds are described. The new features are demonstrated by additional example programs.

Detection of Higgs bosons decaying to bottom quarks

Gilman, F.J.; Price, L.E.

1986-11-01

Several developments affecting the possibility of Higgs detection are discussed. These include the level of certainty about the t quark mass, Monte Carlo programs to generate both signal and background events, and separation and/or enhancement of heavy quark jets from jets due to light quarks or gluons, and the possibility that the neutral Higgs decay into bottom quarks might be the decay mode of choice for detecting the intermediate mass Higgs. Possible means of detection of an intermediate mass Higgs at the SSC, particularly if a prominent decay mode is to bottom quarks, are examined, using the PYTHIA Monte Carlo program to generate both signal and background events. For the signal, events were generated in which Higgs bosons are created in proton-proton collisions, with the Higgs decaying into bottom quarks. The presence of W or Z bosons, created in the same proton-proton collision, is used to enhance the likelihood of Higgs production and to reduce the potentially enormous background. It is found that the Higgs decay to bottom quarks, if important, would be more favorable for detection of the Higgs than decay to top quarks was found to be because of the smaller background. 3 refs., 4 figs

Exclusion limits on heavy neutral MSSM Higgs bosons A/H decaying to a pair of top quarks in pp collisions at √s = 13 TeV

2017-01-01

A search for heavy scalar H and pseudoscalar A neutral Higgs bosons at the LHC in their production in the gluon-fusion mechanism and their decays into a top quark pair is presented. This analysis uses the dataset with an integrated luminosity of 35.9fb−1 of pp collision collected by the CMS experiment in 2016, at a center-of-mass energy of √s = 13 TeV. The results are interpreted in the context of the Minimal Supersymmetric Standard Model (MSSM). Interference effect between signal process and Standard Model tt¯production is being considered. Upper limits are set on the coupling modifier within the hMSSM benchmark scenario as a function of the Higgs mass MA/H and the ratio of vacuum expectation value of the Higgs doublet field tan β for 400 6 MA/H 6 750 GeV. Extrapolation of results is made for prediction of exclusion limits at luminosities of 100 and 1000 pb−1.

In any scenario of the electroweak baryogenesis, the profile of the CP violating bubble wall, created at the first-order phase transition, plays an essential role. We attempt to determine it by solving the equations of motion for the scalars in the two-Higgs-doublet model at the transition temperature. According to the parameters in the potential, we found three solutions. Two of them smoothly connect the CP-violating broken phase and the symmetric phase, while the other connects CP-conserving vacua but violates CP in the intermediate region. We also estimate the chiral charge flux, which will be turned into the baryon density in the symmetric phase by the sphaleron process. (author).

CP violating observables in e$^{-}$e$^{+}$ --> W$^{-}$W$^{+}$

CERN Document Server

Chang, D; Phillips, I

1993-01-01

We consider various integrated lepton charge-energy asymmetries and azimuthal asymmetries as tests of CP violation in the process $e^-e^+ \\to W^-W^+$. These asymmetries are sensitive to different linear combinations of the CP violating form factors in the three gauge boson $W^-W^+$ production vertex, and can distinguish dispersive and absorptive parts of the form factors. It makes use of purely hadronic and purely leptonic modes of $W$'s decays as well as the mixed modes. The techniques of using the kinematics of jets or missing momentum to construct CP--odd observables are also employed. These CP violating observables are illustrated in the generalized Left-Right Model and the Charged Higgs Model.

We have performed the first search for CP violation in tau lepton decay. CP violation in lepton decay does not occur in the minimal standard model but can occur in extensions such as the multi-Higgs doublet model. It appears as a characteristic difference between the {tau}{sup {minus}} and {tau}{sup +} decay angular distributions for the semileptonic decay modes such as {tau}{sup {minus}}{r_arrow}K{sup 0}{pi}{sup {minus}}{nu} . We define an observable asymmetry to exploit this and find no evidence for any CP violation. {copyright} {ital 1998} {ital The American Physical Society }

Enhanced lepton flavour violation in the supersymmetric inverse seesaw

International Nuclear Information System (INIS)

Weiland, C

2013-01-01

In minimal supersymmetric seesaw models, the contribution to lepton flavour violation from Z-penguins is usually negligible. In this study, we consider the supersymmetric inverse seesaw and show that, in this case, the Z-penguin contribution dominates in several lepton flavour violating observables due to the low scale of the inverse seesaw mechanism. Among the observables considered, we find that the most constraining one is the μ-e conversion rate which is already restricting the otherwise allowed parameter space of the model. Moreover, in this framework, the Z-penguins exhibit a non-decoupling behaviour, which has previously been noticed in lepton flavour violating Higgs decays

ATLAS performed searches for heavy Higgs bosons, whose presence would establish the existance of new physics. Searches for charged and neutral Higgs bosons are carried out using 8 or 13 TeV data for various production modes and in many different final states. The searches all yield null results. Exclusions limits are set on the production cross section and on parameters in various benchmark models.

We present strategies to search for heavy neutral Higgs bosons decaying to top quark pairs, as often occurs at low tan β in type II two Higgs doublet models such as the Higgs sector of the MSSM. The resonant production channel is unsatisfactory due to interference with the SM background. We instead propose to utilize same-sign dilepton signatures arising from the production of heavy Higgs bosons in association with one or two top quarks and subsequent decay to a top pair. We find that for heavier neutral Higgs bosons the production in association with one top quark provides greater sensitivity than production in association with two top quarks. We obtain current limits at the LHC using Run I data at 8 TeV and forecast the sensitivity of a dedicated analysis during Run II at 14 TeV. Then we perform a detailed BDT study for the 14 TeV LHC and a future 100 TeV collider.

Lectures on Higgs Boson Physics in the Standard Model and Beyond

CERN Document Server

Wells, James D

2009-01-01

These lectures focus on the structure of various Higgs boson theories. Topics in the first lectures include: mass generation in chiral theories, spontaneous symmetry breaking, neutrino masses, perturbative unitarity, vacuum stability, vacuum alignment, flavor changing neutral current solutions with multiple Higgs doublets, analysis of type I theory with Z2 symmetry, and rephasing symmetries. After an Essay on the Hierarchy Problem, additional topics are covered that more directly relate to naturalness of the electroweak theory. Emphasis is on their connection to Higgs boson physics. Topics in these later lectures include: supersymmetry, supersymmetric Higgs sector in the Runge basis, leading-order radiative corrections of supersymmetric light Higgs boson mass, theories of extra dimensions, and radion mixing with the Higgs boson in warped extra dimensions. And finally, one lecture is devoted to Higgs boson connections to the hidden sector.

On radiative corrections to supersymmetric Higgs boson masses and their implications for LEP searches

Ellis, J.; Zwirner, F.

1991-01-01

We present calculations of the one-loop radiative corrections to the mass of the neutral CP-odd Higgs boson (A) in the minimal supersymmetric extension of the standard model, as well as to the neutral CP-even Higgs (h, H) masses and mixing angles. We use these results to recalculate the cross-sections for Higgs production at LEP in the h + (Z * + fanti f), h (H)Z 0 and h (H) A final states. We delineate the domains of parameter space accessible at LEP at the Z 0 peak and at LEP II with a center-of-mass energy of 180, 190 or 200 GeV. (orig.)

Higgs couplings and supersymmetry in the light of early LHC results

International Nuclear Information System (INIS)

Stefaniak, Tim

2014-07-01

We present phenomenological studies investigating the implications of early results from the Large Hadron Collider (LHC) for models beyond the Standard Model (BSM), mostly focusing on Supersymmetry (SUSY). Our work covers different aspects in this wide field of research. We describe the development and basic concepts of the public computer codes HiggsBounds (version 4) and HiggsSignals. These confront the Higgs sector predictions of BSM models with results from LEP, Tevatron and LHC Higgs searches. While HiggsBounds tests the model against experimental null-results, HiggsSignals evaluates the model's chi-squared compatibility with the signal rate and mass measurements of the Higgs boson, that was discovered by the LHC in 2012. We then perform a systematic study of potential deviations in the Higgs couplings from their Standard Model (SM) prediction. No significant deviations are found. Future capabilities of Higgs coupling determination at the later LHC stages and at the International Linear Collider (ILC) are explored. We also study the implications of the Higgs discovery for the Minimal Supersymmetric Standard Model (MSSM), considering either the light or the heavy CP-even Higgs boson as the discovered state. We show that both interpretations are viable and discuss their phenomenology. Finally, we study the LHC signatures of resonant scalar lepton production, which may arise in SUSY models with R-parity violation (RPV). These are confronted with early LHC results, yielding constraints on the relevant RPV operators.

Search for a charged Higgs boson in $\\tau\

AUTHOR|(INSPIRE)INSPIRE-00011001; Gallinaro, Michele

The Large Hadron Collider (LHC) started the first proton-proton collisions at a center-of-mass energy of 7 TeV in 2010. Soon thereafter, the experiments started collecting data and were able to rediscover the Standard Model (SM) in a few months, thanks to the very good understanding of the detectors, and their already precise calibrations. The LHC took data at $\\sqrt{s}=7$~TeV and 8~TeV in the years 2010-2011 and 2012, respectively: the peak of his intensive data taking has been, in 2012, the discovery, by the CMS and ATLAS experiment s, of a neutral boson with a mass of approximately 125\\unit{\\GeV}. The properties of the new boson are consistent with those predicted for the Standard Model (SM) Higgs boson, and models with an extended Higgs sector are constrained by the measured properties of the new boson: the discovery of another scalar boson, neutral or charged, would represent unambig uous evidence for the presence of physics beyond the SM. Charged Higgs bosons are predicted in models consisting of at...

In this article we analyze the impact of B-physics and Higgs physics at LEP on standard and non-standard Higgs bosons searches at the Tevatron and the LHC, within the framework of minimal flavor violating supersymmetric models. The B-physics constraints we consider come from the experimental measurements of the rare B-decays b {yields} s{gamma} and B{sub u} {yields} {tau}{nu} and the experimental limit on the B{sub s} {yields} {mu}{sup +}{mu}{sup -} branching ratio. We show that these constraints are severe for large values of the trilinear soft breaking parameter A{sub t}, rendering the non-standard Higgs searches at hadron colliders less promising. On the contrary these bounds are relaxed for small values of A{sub t} and large values of the Higgsino mass parameter {mu}, enhancing the prospects for the direct detection of non-standard Higgs bosons at both colliders. We also consider the available ATLAS and CMS projected sensitivities in the standard model Higgs search channels, and we discuss the LHC's ability in probing the whole MSSM parameter space. In addition we also consider the expected Tevatron collider sensitivities in the standard model Higgs h {yields} b{bar b} channel to show that it may be able to find 3 {sigma} evidence in the B-physics allowed regions for small or moderate values of the stop mixing parameter.

Inhomogeneity driven by Higgs instability in a gapless superconductor

Giannakis, Ioannis; Hou Defu; Huang Mei; Ren Haicang

2007-01-01

The fluctuations of the Higgs and pseudo Nambu-Goldstone fields in the 2-flavor color superconductivity (2SC) phase with mismatched pairing are described in the nonlinear realization framework of the gauged Nambu-Jona-Lasinio model. In the gapless 2SC phase, not only Nambu-Goldstone currents can be spontaneously generated, but also the Higgs field exhibits instablity. The Nambu-Goldstone currents generation indicates the formation of the single plane wave Larkin-Ovchinnikov-Fulde-Ferrel state and breaks rotation symmetry, while the Higgs instability favors spatial inhomogeneity and breaks translation invariance. In this paper, we focus on the Higgs instability which has not drawn much attention yet. The Higgs instability cannot be removed without a long range force, thus it persists in the gapless superfluidity and induces phase separation. In the case of gapless 2-flavor color superconductivity state, the Higgs instability can only be partially removed by the electric Coulomb energy. However, it is not excluded that the Higgs instability might be completely removed in the charge neutral gapless color-flavor locked phase by the color Coulomb energy

Higgs-Stoponium Mixing Near the Stop-Antistop Threshold

Bodwin, Geoffrey T; Wagner, Carlos E M

2016-01-01

Supersymmetric extensions of the standard model contain additional heavy neutral Higgs bosons that are coupled to heavy scalar top quarks (stops). This system exhibits interesting field theoretic phenomena when the Higgs mass is close to the stop-antistop production threshold. Existing work in the literature has examined the digluon-to-diphoton cross section near threshold and has focused on enhancements in the cross section that might arise either from the perturbative contributions to the Higgs-to-digluon and Higgs-to-diphoton form factors or from mixing of the Higgs boson with stoponium states. Near threshold, enhancements in the relevant amplitudes that go as inverse powers of the stop-antistop relative velocity require resummations of perturbation theory and/or nonperturbative treatments. We present a complete formulation of threshold effects at leading order in the stop-antistop relative velocity in terms of nonrelativistic effective field theory. We give detailed numerical calculations for the case in ...

Extended Higgs sectors in the context of supersymmetry at the LHC

2016-01-01

Full Text Available We study an extension of the Higgs sector of the Standard Model (SM with SU(2 triplet and a SM gauge singlet in the context of supersymmetry. For a Z3 symmetric superpotential where the singlet field generates the bilinear Higgs mixing term between the two Higgs doublets dynamically. Models like this, often have a very light pseudoscalar as a pseudo-Nambu Goldstone model of an extra U(1 symmetry. We investigate the possibility of such light hidden Higgs boson with the data of the discovered Higgs boson around 125 GeV. Along with the neutral sector, the charged Higgs bosons in the triplet extended case are really interesting. For instance, the triplet charged Higgs bosons give rise to new decay mode to ZW± along with an a1W± final state, due to the existence of a light pseudoscalar. These new modes can be looked for at the LHC in the search for Higgs bosons in other representations of SU(2.

The present measurements of the branching fraction and CP-violating asymmetries for neutral B decays to D* sup+- D sup+-. The measurement uses a data sample for approximately 88 million UPSILON(4S) -> B(bar B) decays collected with the BABAR detector at the SLAC PEP-II asymmetric-energy B factory. They measure the branching fraction to be (8.8 +- 1.0 +- 1.3) x 10 sup - sup 4 and the time-integrated CP-violating asymmetry between the rates to D* sup - D sup + and D* sup + D sup - to be ALPHA = -0.03 +- 0.11 +- 0.05. They also measure the time-dependent CP-violating asymmetry parameters to be S sub - sub + = -0.24 +- 0.69 +- 0.12, C sub - sub + = -0.22 +- 0.37 +- 0.10 for B -> D* sup - D sup + and S sub + sub - = -0.82 +- 0.75 +- 0.14, C sub + sub - = -0.47 +- 0.40 +- 0.12 for B -> D* sup + D sup -. In each case the first error is statistical and the second error is systematic.

We examine the feasibility of identifying in a hadron machine the standard, neutral Higgs boson, produced in association with a W, when the mass of the Higgs is between approximately 100 GeV and 2m/sub W/.

Possible backgrounds arising from the continuum production of tt-bar, tb-bar, or t-barb accompanied by a W are computed as well

Parity violation in electron scattering

2007-09-01

The elaboration of the electroweak standard model from the discovery of parity violation to the weak neutral current is described in the first chapter. In the second chapter the author discusses the 2 experimental approaches of the parity violation experiments. In the first approach the weak neutral current can be assumed to be well known and can be used as a probe for the hadronic matter. The second approach consists in measuring the weak neutral current between 2 particles with known internal structure in order to test the predictions of the standard model in the low energy range. The chapters 3 and 4 are an illustration of the first approach through the HAPPEx series of experiments that took place in the Jefferson Laboratory from 1998 to 2005. The HAPPEx experiments aimed at measuring the contribution of strange quarks in the electromagnetic form factors of the nucleon through the violation of parity in the elastic scattering at forward angles. The last chapter is dedicated to the E158 experiment that was performed at the Slac (California) between 2000 and 2003. The weak neutral current was measured between 2 electrons and the high accuracy obtained allowed the physics beyond the standard model to be indirectly constraint up to a few TeV. (A.C.)

We explore possible asymmetric dark matter models using CP violating scatterings to generate an asymmetry. In particular, we introduce a new model, based on DM fields coupling to the SM Higgs and lepton doublets, a neutrino portal, and explore its UV completions. We study the CP violation and asymmetry formation of this model, to demonstrate that it is capable of producing the correct abundance of dark matter and the observed matter-antimatter asymmetry. Crucial to achieving this is the introduction of interactions which violate CP with a T{sup 2} dependence.

Full text: We have investigated new aspects related to the four-dimensional abelian gauge-Higgs model with the addition of the Carroll-Field-Jackiw term (CFJ). We have focused on one-loop quantum corrections to the photon and Higgs sectors and we have analyzed what kind of effects are induced at the quantum level by spontaneous gauge symmetry breaking due the presence of the CFJ term. We have shown that new finite and non-ambiguous Lorentz-breaking terms are induced in both sectors at second order in the background vector. Specifically in the pure gauge sector, a CPT-even aether term (free from ambiguities) is induced. A CPT-even term is also induced in the pure Higgs sector. Both terms have been mapped in the Standard Model Extension. Besides, aspects of the one-loop renormalization of the background vector dependent terms have been studied. The new divergences due the presence of the CFJ term were shown to be worked out by the renormalization condition which requires the vanishing of the vacuum expectation value of the Higgs field. So at one loop the CFJ term does not spoil the well known renormalizability of the model without Lorentz symmetry breaking terms. The calculations have been done within dimensional methods and in an arbitrary gauge choice. (author)

Higgs boson production and decay at e+e− colliders as a probe of the Left–Right twin Higgs model

Full Text Available In the framework of the Left–Right twin Higgs (LRTH model, we consider the constrains from the latest search for high-mass dilepton resonances at the LHC and find that the heavy neutral boson ZH is excluded with mass below 2.76 TeV. Under these constrains, we study the Higgs–Gauge coupling production processes e+e−→ZH, e+e−→νeνe¯H and e+e−→e+e−H, top quark Yukawa coupling production process e+e−→tt¯H, Higgs self-couplings production processes e+e−→ZHH and e+e−→νeνe¯HH at e+e− colliders. Besides, we study the major decay modes of the Higgs boson, namely h→ff¯(f=b,c,τ, VV⁎(V=W,Z, gg, γγ. We find that the LRTH effects are sizable so that the Higgs boson processes at e+e− collider can be a sensitive probe for the LRTH model.

$CPT$ violation searches and prospects for LHCb

van Tilburg, Jeroen

2015-03-06

An overview of current experimental bounds on $CPT$ violation in neutral meson mixing is given. New values for the $CPT$ asymmetry in the $B^0$ and $B_s^0$ systems are deduced from BaBar, Belle and LHCb data. With dedicated analyses, LHCb will be able to further improve the bounds on $CPT$ violation in the $D^0$, $B^0$ and $B_s^0$ systems. Since $CPT$ violation implies violation of Lorentz invariance, the observed $CPT$ asymmetry will exhibit sidereal- and boost-dependent variations. Such $CPT$-violating and Lorentz-violating effects are accommodated in the framework of the Standard-Model Extension (SME). The large boost of the neutral mesons produced at LHCb results in a high sensitivity to the corresponding SME coefficients. For the $B^0$ and $B_s^0$ systems, using existing LHCb data, we determine with high precision the SME coefficients that are not varying with sidereal time. With a full sidereal analysis, LHCb will be able to improve the existing SME bounds in the $D^0$, $B^0$ and $B_s^0$ systems by up t...

LHC Higgs physics beyond the Standard Model

Spannowsky, M.

2007-01-01

The Large Hadron Collider (LHC) at CERN will be able to perform proton collisions at a much higher center-of-mass energy and luminosity than any other collider. Its main purpose is to detect the Higgs boson, the last unobserved particle of the Standard Model, explaining the riddle of the origin of mass. Studies have shown, that for the whole allowed region of the Higgs mass processes exist to detect the Higgs at the LHC. However, the Standard Model cannot be a theory of everything and is not able to provide a complete understanding of physics. It is at most an effective theory up to a presently unknown energy scale. Hence, extensions of the Standard Model are necessary which can affect the Higgs-boson signals. We discuss these effects in two popular extensions of the Standard Model: the Minimal Supersymmetric Standard Model (MSSM) and the Standard Model with four generations (SM4G). Constraints on these models come predominantly from flavor physics and electroweak precision measurements. We show, that the SM4G is still viable and that a fourth generation has strong impact on decay and production processes of the Higgs boson. Furthermore, we study the charged Higgs boson in the MSSM, yielding a clear signal for physics beyond the Standard Model. For small tan β in minimal flavor violation (MFV) no processes for the detection of a charged Higgs boson do exist at the LHC. However, MFV is just motivated by the experimental agreement of results from flavor physics with Standard Model predictions, but not by any basic theoretical consideration. In this thesis, we calculate charged Higgs boson production cross sections beyond the assumption of MFV, where a large number of free parameters is present in the MSSM. We find that the soft-breaking parameters which enhance the charged-Higgs boson production most are just bound to large values, e.g. by rare B-meson decays. Although the charged-Higgs boson cross sections beyond MFV turn out to be sizeable, only a detailed

CP Violation

1993-06-01

The violation of the CP symmetry is a phenomenon, the origin of which is not yet well established and deserves a particular attention since it may be a fundamental property of Nature with very important consequences for the evolution of the universe. We propose in these lectures to have an overview of this phenomenon as we understand it so far. To this end, and after introducing the discrete space-time symmetries, we discuss the observation of the violation of the CP symmetry in the neutral kaon decays. We then derive the general formalism for any neutral system made of a particle and its antiparticle and discuss how CP violation is introduced. We show how this phenomenon is generated in the Standard Model of the electroweak interactions and what are the predictions that can be made. In particular we shall concentrate on the expected effects in the decays of mesons involving the b quark. We review the various possibilities for observing these effects, calculate their magnitudes and show how the consistency of the theory can be tested. Finally, we outline the experimental prospects for studying CP non conservation at an asymmetric B Factory to either verify the Standard Model mechanism or provide evidence for new physics. (author)

Suppression of flavor violation in an A4 warped extra dimensional model

International Nuclear Information System (INIS)

Kadosh, Avihay

2011-01-01

In an attempt to simultaneously explain the observed masses and mixing patterns of both quarks and leptons, we recently proposed a model (JHEP08(2010)115) based on the non abelian discrete flavor group A 4 , implemented in a custodial RS setup with a bulk Higgs. We showed that the standard model flavor structure can be realized within the zero mode approximation (ZMA), with nearly TBM neutrino mixing and a realistic CKM matrix with rather mild assumptions. An important advantage of this framework with respect to flavor anarchic models is the vanishing of the dangerous tree level KK gluon contribution to ε K and the suppression of the new physics one loop contributions to the neutron EDM, ε'/ε, b → Sγ and Higgs mediated flavor changing neutral current (FCNC) processes. These results are obtained beyond the ZMA, in order to account for the the full flavor structure and mixing of the zero modes and first Kaluza-Klein (KK) modes of all generations. The resulting constraints on the KK mass scale are shown to be significantly relaxed compared to the flavour anarchic case, showing explicitly the role of non abelian discrete flavor symmetries in relaxing flavor violation bounds within the RS setup. As a byproduct of our analysis we also obtain the same contributions for the custodial anarchic case with two SU(2) R doublets for each fermion generation.

We present a qualitatively new approach to discover Higgs bosons of the MSSM at the LHC using jet substructure techniques applied to boosted Higgs decays. These techniques are ideally suited to the MSSM, since the lightest Higgs boson overwhelmingly decays to b(bar b) throughout the entire parameter space, while the heavier neutral Higgs bosons, if light enough to be produced in a cascade, also predominantly decay to b(bar b). The Higgs production we consider arises from superpartner production where superpartners cascade decay into Higgs bosons. We study this mode of Higgs production for several superpartner hierarchies: m # tilde q#,m # tilde g# > m # tilde W#, # tilde B# > m h + μ; m(tilde q);m # tilde q#,m # tilde g# > m # tilde W#, # tilde B# > m h,H,A + μ; and m # tilde q#,m # tilde g# > m # tilde W# > m h + μ with m # tilde B# ∼ μ. In these cascades, the Higgs bosons are boosted, with pT > 200 GeV a large fraction of the time. Since Higgs bosons appear in cascades originating from squarks and/or gluinos, the cross section for events with at least one Higgs boson can be the same order as squark/gluino production. Given 10 fb -1 of 14 TeV LHC data, with m # tilde q# ∼< 1 TeV, and one of the above superpartner mass hierarchies, our estimate of S√ B of the Higgs signal is sufficiently high that the b(bar b) mode can become the discovery mode of the lightest Higgs boson of the MSSM.

Flavor and CP invariant composite Higgs models

The flavor protection in composite Higgs models with partial compositeness is known to be insufficient. We explore the possibility to alleviate the tension with CP odd observables by assuming that flavor or CP are symmetries of the composite sector, broken by the coupling to Standard Model fields. One realization is that the composite sector has a flavor symmetry SU(3) or SU(3) U x SU(3) D which allows us to realize Minimal Flavor Violation. We show how to avoid the previously problematic tension between a flavor symmetric composite sector and electro-weak precision tests. Some of the light quarks are substantially or even fully composite with striking signals at the LHC. We discuss the constraints from recent dijet mass measurements and give an outlook on the discovery potential. We also present a different protection mechanism where we separate the generation of flavor hierarchies and the origin of CP violation. This can eliminate or safely reduce unwanted CP violating effects, realizing effectively ''Minimal CP Violation'' and is compatible with a dynamical generation of flavor at low scales. (orig.)

Measurement of the Higgs boson coupling with tau leptons and search for an additional neutral MSSM Higgs boson with the ATLAS detector

CERN Document Server

AUTHOR|(INSPIRE)INSPIRE-00376986

The aim of this thesis is the search for the Standard Model Higgs boson and for additional heavy MSSM Higgs bosons in the $\\tau\\tau$ channel with the ATLAS detector of the LHC. The search for the Higgs boson predicted by the Standard Model is performed using the full integrated luminosity of the Run 1 of the LHC: 4.5 fb$^{-1}$ of data collected at an energy in the center of mass of 7 TeV and 20.3 fb$^{-1}$ of data collected at an energy in the center of mass of 8 TeV. The analysis enhances the sensitivity to signal events by implementing a Boosted Decision Tree trained on the signal and background models. The BDT score distribution shows an excess of data over the background expectation, with an observed (expected) statistical significance of 4.5 $\\sigma$ (3.4 $\\sigma$), which provides evidence for the direct coupling of the Higgs boson to fermions. The measured signal strength normalized to the Standard Model expectation of $\\mu = 1.43^{+0.43}_{-0.37}$ is consistent with the predicted Yukawa coupling strengt...

In superfluids the order parameter, which describes spontaneous symmetry breaking, is an analogue of the Higgs field in the Standard Model of particle physics. Oscillations of the field amplitude are massive Higgs bosons, while oscillations of the orientation are massless Nambu-Goldstone bosons. The 125 GeV Higgs boson, discovered at Large Hadron Collider, is light compared with electroweak energy scale. Here, we show that such light Higgs exists in superfluid (3)He-B, where one of three Nambu-Goldstone spin-wave modes acquires small mass due to the spin-orbit interaction. Other modes become optical and acoustic magnons. We observe parametric decay of Bose-Einstein condensate of optical magnons to light Higgs modes and decay of optical to acoustic magnons. Formation of a light Higgs from a Nambu-Goldstone mode observed in (3)He-B opens a possibility that such scenario can be realized in other systems, where violation of some hidden symmetry is possible, including the Standard Model.

Search for Neutral Higgs Bosons of the Minimal Supersymmetric Standard Model in the $\\tau_{e} \\tau_{\\mu}$ Decay Mode at $\\sqrt{s}$ = 7 TeV with the ATLAS Detector

CERN Document Server

Radziewski, Holger von

This thesis presents a search for neutral Higgs bosons (phi^0) of the Minimal Supersymmetric Standard Model (MSSM) in the decay mode phi^0 -> tau tau -> e mu + 4nu. The analysis uses a dataset that corresponds to an integrated luminosity of 4.7/fb of proton collision data collected with the ATLAS Experiment at the Large Hadron Collider (LHC) at a center–of–mass energy of 7 TeV. The search makes use of events with one reconstructed electron and one reconstructed muon in the final state. In the MSSM, neutral Higgs bosons are produced predominantly in gluon fusion events and in association with b-quarks. Events are therefore categorized according to the absence or presence of exactly one jet identified as stemming from a b-quark. The dominant backgrounds (Z/gamma^* -> tau tau -> e mu + 4nu, top quark pair production, and multi-jet events) are estimated using data-driven techniques. No significant excess is observed. Therefore, upper limits on the product of the production cross-section and the branching fr...

We present a qualitatively new approach to discover Higgs bosons of the minimal supersymmetric standard model (MSSM) at the LHC using jet substructure techniques applied to boosted Higgs decays. These techniques are ideally suited to the MSSM, since the lightest Higgs boson overwhelmingly decays to bb throughout the entire parameter space, while the heavier neutral Higgs bosons, if light enough to be produced in a cascade, also predominantly decay to bb. The Higgs production we consider arises from superpartner production where superpartners cascade decay into Higgs bosons. We study this mode of Higgs production for several superpartner hierarchies: m q -tilde, m g -tilde>m W -tilde ,B -tilde>m h +μ; m q -tilde, m g -tilde>m W -tilde ,B -tilde>m h,H,A +μ; and m q -tilde, m g -tilde>m W -tilde>m h +μ with m B -tilde≅μ. In these cascades, the Higgs bosons are boosted, with p T >200 GeV a large fraction of the time. Since Higgses appear in cascades originating from squarks and/or gluinos, the cross section for events with at least one Higgs can be the same order as squark/gluino production. Given 10 fb -1 of 14 TeV LHC data, with m q -tilde < or approx. 1 TeV, and one of the above superpartner mass hierarchies, our estimate of S/√(B) of the Higgs signal is sufficiently high that the bb mode can become the discovery mode of the lightest Higgs boson of the MSSM.

Higgs production via weak boson fusion in the standard model and the MSSM

2010-12-01

Weak boson fusion is expected to be an important Higgs production channel at the LHC. Complete one-loop results for weak boson fusion in the Standard Model have been obtained by calculating the full virtual electroweak corrections and photon radiation and implementing these results into the public Monte Carlo program VBFNLO (which includes the NLO QCD corrections). Furthermore the dominant supersymmetric one-loop corrections to neutral Higgs production, in the general case where the MSSM includes complex phases, have been calculated. These results have been combined with all one-loop corrections of Standard Model type and with the propagator-type corrections from the Higgs sector of the MSSM up to the two-loop level. Within the Standard Model the electroweak corrections are found to be as important as the QCD corrections after the application of appropriate cuts. The corrections yield a shift in the cross section of order 5% for a Higgs of mass 100-200 GeV, confirming the result obtained previously in the literature. For the production of a light Higgs boson in the MSSM the Standard Model result is recovered in the decoupling limit, while the loop contributions from superpartners to the production of neutral MSSM Higgs bosons can give rise to corrections in excess of 10% away from the decoupling region.

Searching for Higgs bosons beyond the Standard Model (BSM) is one of the most important missions for hadron colliders. As a landmark of BSM physics, the MSSM Higgs sector at the LHC is expected to be tested up to the scale of the decoupling limit of O(1) TeV, except for a wedge region centered around tan β∼3–10, which has been known to be difficult to probe. In this article, we present a dedicated study testing the decoupled MSSM Higgs sector, at the LHC and a next-generation pp-collider, proposing to search in channels with associated Higgs productions, with the neutral and charged Higgs further decaying into tt and tb, respectively. In the case of neutral Higgs we are able to probe for the so far uncovered wedge region via pp→bbH/A→bbtt. Additionally, we cover the the high tan β range with pp→bbH/A→bbττ. The combination of these searches with channels dedicated to the low tan β region, such as pp→H/A→tt and pp→ttH/A→tttt potentially covers the full tan β range. The search for charged Higgs has a slightly smaller sensitivity for the moderate tan β region, but additionally probes for the higher and lower tan β regions with even greater sensitivity, via pp→tbH{sup ±}→tbtb. While the LHC will be able to probe the whole tan β range for Higgs masses of O(1) TeV by combining these channels, we show that a future 100 TeV pp-collider has a potential to push the sensitivity reach up to ∼O(10) TeV. In order to deal with the novel kinematics of top quarks produced by heavy Higgs decays, the multivariate Boosted Decision Tree (BDT) method is applied in our collider analyses. The BDT-based tagging efficiencies of both hadronic and leptonic top-jets, and their mutual fake rates as well as the faking rates by other jets (h, Z, W, b, etc.) are also presented.

We summarize the prospects for Higgs boson physics at future proton-proton colliders with centre of mass (c.m.) energies up to 100 TeV. We first provide the production cross sections for the Higgs boson of the Standard Model from 13 TeV to 100 TeV, in the main production mechanisms and in subleading but important ones such as double Higgs production, triple production and associated production with two gauge bosons or with a single top quark. We then discuss the production of Higgs particles in beyond the Standard Model scenarios, starting with the one in the continuum of a pair of scalar, fermionic and vector dark matter particles in Higgs-portal models in various channels with virtual Higgs exchange. The cross sections for the production of the heavier CP-even and CP-odd neutral Higgs states and the charged Higgs states in two-Higgs doublet models, with a specific study of the case of the Minimal Supersymmetric Standard Model, are then given. The sensitivity of a 100 TeV proton machine to probe the new Higgs states is discussed and compared to that of the LHC with a c.m. energy of 14 TeV and at high luminosity.

We investigate the sensitivity of observables measurable in e^+ e^-, gamma gamma and mu^+ mu^- collisions for distinguishing the properties of the light neutral CP-even Higgs boson in the minimal supersymmetric extension of the Standard Model (MSSM) from those of a Standard Model (SM) Higgs boson with the same mass. We explore first the available parameter space in the constrained MSSM (CMSSM), with universal soft supersymmetry-breaking parameters, incorporating the most recent direct limits on sparticle and Higgs masses, the indirect constraints from b to s gamma and g_mu - 2, and the cosmological relic density. We calculate the products of the expected CMSSM Higgs production cross sections and decay branching ratios sigma X B normalized by the corresponding values expected for those of a SM Higgs boson of the same mass. The results are compared with the precisions expected at each collider, and allow for a direct comparison of the different channels. The measurements in the Higgs sector are found to provide...

The goal of this report is to summarize the current situation and discuss possible search strategies for charged scalars, in non-supersymmetric extensions of the Standard Model at the LHC. Such scalars appear in Multi-Higgs-Doublet models (MHDM), in particular in the popular Two-Higgs-Doublet model (2HDM), allowing for charged and more neutral Higgs bosons. These models have the attractive property that electroweak precision observables are automatically in agreement with the Standard Model at the tree level. For the most popular version of this framework, Model~II, a discovery of a charged Higgs boson remains challenging, since the parameter space is becoming very constrained, and the QCD background is very high. We also briefly comment on models with dark matter which constrain the corresponding charged scalars that occur in these models. The stakes of a possible discovery of an extended scalar sector are very high, and these searches should be pursued in all conceivable channels, at the LHC and at future c...

CP violation in B decays

International Nuclear Information System (INIS)

Kayser, B.

1990-01-01

The study of CP-violating effects in B decays will be a good test of whether CP violation is caused by the known weak interaction. If this is its origin, then large, cleanly-predicted CP-violating effects are expected in certain neutral B decays to hadronic CP eigenstates. The phenomenology of CP violation in the B system is reviewed, and the genesis of these large effects is explained. In this it is shown that large, cleanly-predicted effects are also expected in some decays to states which are not CP eigenstates. The combined study of the latter decays and those to CP eigenstates may make it possible to obtain a statistically-significant CP-violating signal with fewer B mesons that would otherwise be required

Models of extended gauge mediation, in which large A-terms arise through direct messenger-MSSM superpotential couplings, are well-motivated by the discovery of the 125 GeV Higgs. However, since these models are not necessarily MFV, the flavor constraints could be stringent. In this paper, we perform the first detailed and quantitative study of the flavor violation in these models. To facilitate our study, we introduce a new tool called FormFlavor for computing precision flavor observables in the general MSSM. We validate FormFlavor and our qualitative understanding of the flavor violation in these models by comparing against analytical expressions. Despite being non-MFV, we show that these models are protected against the strongest constraints by a special flavor texture, which we dub chiral flavor violation (χFV). This results in only mild bounds from current experiments, and exciting prospects for experiments in the near future.

Soft CP violation in K-meson systems

We consider a model with soft CP violation which accommodates the CP violation in the neutral kaons even if we assume that the Cabibbo-Kobayashi-Maskawa mixing matrix is real and the sources of CP violation are three complex vacuum expectation values and a trilinear coupling in the scalar potential. We show that for some reasonable values of the masses and other parameters the model allows us to explain all the observed CP violation processes in the K 0 -K 0 system

Baryon number violation and multiple production of W and Higgs bosons are described semiclassically in terms of the instanton-anti-instanton valley. We find (i) two saddle points, one describing reflection from a barrier and the other describing tunneling through it. We find (ii) a critical energy Ec~35 TeV where the cross section is suppressed as exp(-const/g2w), but the formulas are no longer valid; (iii) however, depending on the (still uncertain) Higgs bosson action, the cross section at this point may be large enough to be observable.

A set of results related to the new particles searches in LHCb are reported. Upper limits on the cross section times branching fraction of neutral Higgs boson decaying into two tau leptons have been set in the model independent search and in the Minimal Supersymmetric Model. Many theoretical models predict the existence of the Higgs bosons decaying into heavy long-lived particles. The upper limit on their production cross section has been determined for several combinations of parameters. A measurement of the cross section for the production of $b\\overline{b}$ and $c\\overline{c}$ pairs based on inclusive final states has been performed in a region of pseudorapidity 2.5 5 GeV of the $b$ hadron candidate, resulting in $\\sigma$ $(b\\overline{b})$ = $7.7 \\pm 0.12 (stat) \\pm 0.84 (syst)$ and $\\sigma$ $(c\\overline{c})$ = $104.6 \\pm 2.7 (stat) \\pm 11.4 (syst)$.

Search for a Neutral Long-Lived Particle Decaying to B-Jets

Johnson, Chad [Columbia Univ., New York, NY (United States)

2009-04-01

The existence of the Higgs boson is required by the Standard Model of particle physics, yet it has not been observed. The precise nature of the Higgs boson is unknown and the mechanism by which it interacts with known Standard Model particles is also not known. Long-lived, electrically neutral hadrons have recently been proposed in hidden-valley models and could constitute a pathway through which the Higgs boson communicates with the Standard Model. Such a scenario may provide a novel path to Higgs discovery at the Tevatron. This thesis describes a search for a neutral, long-lived particle produced in decays of Higgs bosons in p$\\bar{p}$ collisions at a center-of-mass energy of √s = 1.96 TeV, which decays to b-jets and lives long enough to travel at least 1.6 cm before decaying. This analysis uses 3.65 fb ^-1 of data recorded with the Run II D0 detector at the Fermilab Tevatron collider from April 2002 to August of 2008. We perform a search for eight possible hidden-valley scenarios resulting from a Higgs decay. No significant excess over background is observed and cross-section limits are placed at 95% CL.

Soft CP violation and the global matter-antimatter symmetry of the universe

Science.gov (United States)

Senjanovic, G.; Stecker, F. W.

1980-01-01

Scenarios for baryon production are considered within the context of SU(5) and SO(10) grand unified theories where CP violation arises spontaneously. The spontaneous CP symmetry breaking then results in a matter-antimatter domain structure in the universe. Two possible, distinct types of theories of soft CP violation are defined. In the first type the CP nonconservation originates only from the breaking of SU(2) sub L X U(1) symmetry, and in the second type, even at the unification temperature scale, CP violation can emerge as a result of symmetry breaking by the vacuum expectation values of the superheavy Higgs sector scalars.

We present an updated measurement of time-dependent CP-violating asymmetries in neutral B decays with the BABAR detector at the PEP-II asymmetric B Factory at SLAC. This result uses an additional sample of Upsilon(4S) decays collected in 2001, bringing the data available to 32 x 10(6) BB macro pairs. We select events in which one neutral B meson is fully reconstructed in a final state containing charmonium and the flavor of the other neutral B meson is determined from its decay products. The amplitude of the CP-violating asymmetry, which in the standard model is proportional to sin2 beta, is derived from the decay time distributions in such events. The result sin2 beta = 0.59+/-0.14(stat)+/-0.05(syst) establishes CP violation in the B(0) meson system. We also determine absolute value of lambda = 0.93+/-0.09(stat)+/-0.03(syst), consistent with no direct CP violation.

B→ηK* and B→φKs decays in the two Higgs doublet model III

Using the QCD factorization approach, we investigate the large branching ratios of B→ηK * decays and the S φK s anomaly of B→φK s decay in the two Higgs doublet model III. With the contributions of flavour-changing neutral current mediated by the neutral Higgs bosons H 0 , h 0 and A 0 at the tree level, we provide a coherent resolution to these anomalies within the constrained parameter spaces, which are 120 bs λ ss |<136. This will be really interesting in searching for the signs of new physics. (authors)

The flavor protection in composite Higgs models with partial compositeness is known to be insufficient. We explore the possibility to alleviate the tension with CP odd observables by assuming that flavor or CP are symmetries of the composite sector, broken by the coupling to Standard Model fields. One realization is that the composite sector has a flavor symmetry SU(3) or SU(3){sub U} x SU(3){sub D} which allows us to realize Minimal Flavor Violation. We show how to avoid the previously problematic tension between a flavor symmetric composite sector and electro-weak precision tests. Some of the light quarks are substantially or even fully composite with striking signals at the LHC. We discuss the constraints from recent dijet mass measurements and give an outlook on the discovery potential. We also present a different protection mechanism where we separate the generation of flavor hierarchies and the origin of CP violation. This can eliminate or safely reduce unwanted CP violating effects, realizing effectively ''Minimal CP Violation'' and is compatible with a dynamical generation of flavor at low scales. (orig.)

CP-Violating solitons in the early universe

International Nuclear Information System (INIS)

Tornkvist, O.; Riotto, A.

1997-07-01

Solitons in extensions of the Standard Model can serve as localized sources of CP violation. Depending on their stability properties, they may serve either to create or to deplete the baryon asymmetry. The conditions for existence of a particular soliton candidate, the membrane solution of the two-Higgs model, are presented. In the generic case, investigated by Bachas and Tomaras, membranes exist and are metastable for a wide range of parameters. For the more viable supersymmetric case, it is shown that the present-day existence of CP-violating membranes is experimentally excluded, but preliminary studies suggest that they may have existed in the early universe soon after the electroweak phase transition, with important consequences for the baryon asymmetry of the universe

Weinberg-Salam model with two Higgs doublets and the ΔI = 1/2 rule

Branco, G.C.

1977-01-01

It is suggested that the modification in the Higgs sector of the Weinberg-Salam model which is required by CP violation, also provides an explanation for the ΔI = 1/2 enhancement in the non-leptonic decays of strange particles. (orig.) [de

A minimal spontaneous CP violation model with small neutrino mass and SU(2) x U(1) x Z3 symmetry

International Nuclear Information System (INIS)

Geng, C.Q.; Ng, J.N.

1988-04-01

It is shown that spontaneous CP violation and natural flavor conservation can occur in the SU(2) L x U(1) Y model based on two Higgs doublet and one Higgs singlet fields with a Z 3 discrete symmetry. Physical CP nonconservation is purely due to scalar-pseudoscalar mixings. In order for this to be a major source of CP violation a light spin-O boson of mass less than 10 GeV is required. The see-saw mechanism can be implemented to generate small neutrino masses. The model implies a relatively large electric dipole moment for charged leptons and small value for ε'/ε

A test of CP invariance in Higgs boson production via vector-boson fusion using the method of the Optimal Observable is presented. The analysis exploits the decay mode of the Higgs boson into a pair of [Formula: see text] leptons and is based on 20.3 [Formula: see text] of proton-proton collision data at [Formula: see text] = 8 [Formula: see text] collected by the ATLAS experiment at the LHC. Contributions from CP-violating interactions between the Higgs boson and electroweak gauge bosons are described in an effective field theory framework, in which the strength of CP violation is governed by a single parameter [Formula: see text]. The mean values and distributions of CP-odd observables agree with the expectation in the Standard Model and show no sign of CP violation. The CP-mixing parameter [Formula: see text] is constrained to the interval [Formula: see text] at 68% confidence level, consistent with the Standard Model expectation of [Formula: see text].

A test of CP invariance in Higgs boson production via vector-boson fusion using the method of the Optimal Observable is presented. The analysis exploits the decay mode of the Higgs boson into a pair of τ leptons and is based on 20.3 fb{sup -1} of proton-proton collision data at √(s) = 8 TeV collected by the ATLAS experiment at the LHC. Contributions from CP-violating interactions between the Higgs boson and electroweak gauge bosons are described in an effective field theory framework, in which the strength of CP violation is governed by a single parameter d. The mean values and distributions of CP-odd observables agree with the expectation in the Standard Model and show no sign of CP violation. The CP-mixing parameter d is constrained to the interval (-0.11, 0.05) at 68% confidence level, consistent with the Standard Model expectation of d = 0. (orig.)

A test of CP invariance in Higgs boson production via vector-boson fusion using the method of the Optimal Observable is presented. The analysis exploits the decay mode of the Higgs boson into a pair of $\\tau$ leptons and is based on 20.3 fb$^{-1}$ of proton—proton collision data at $\\sqrt{s}$ = 8 TeV collected by the ATLAS experiment at the LHC. Contributions from CP-violating interactions between the Higgs boson and electroweak gauge bosons are described in an effective field theory framework, in which the strength of CP violation is governed by a single parameter $\\tilde{d}$. The mean values and distributions of CP-odd observables agree with the expectation in the Standard Model and show no sign of CP violation. The CP-mixing parameter $\\tilde{d}$ is constrained to the interval [-0.11,0.05] at 68% confidence level, consistent with the Standard Model expectation of $\\tilde{d}=0$.

Lepton number violating signals of the top quark partners in the left-right twin Higgs model

International Nuclear Information System (INIS)

Goh, Hock-Seng; Krenke, Christopher A.

2010-01-01

We study the collider signatures of the left-right twin Higgs model in the case that the right-handed neutrino mass is less than the mass of the right-handed gauge boson. In this scenario, new leptonic decay chains open up, allowing the particles which cancel the one-loop quadratic divergences of the Higgs, the right-handed gauge bosons and top-partners, to be discovered. Half of these events contain same-sign leptons without missing energy, which have no genuine standard model background and for which the backgrounds are purely instrumental. These signals may be used to complement other collider searches and, in certain regions of parameter space, may be the only way to observe the particles responsible for natural electroweak symmetry breaking in the left-right twin Higgs model.

CP violation outside the standard model phenomenology for pedestrians

International Nuclear Information System (INIS)

Lipkin, H.J.

1993-01-01

So far the only experimental evidence for CP violation is the 1964 discovery of K L →2π where the two mass eigenstates produced by neutral meson mixing both decay into the same CP eigenstate. This result is described by two parameters ε and ε'. Today ε ∼ its 1964 value, ε' data are still inconclusive and there is no new evidence for CP violation. One might expect to observe similar phenomena in other systems and also direct CP violation as charge asymmetries between decays of charge conjugate hadrons H ± → f ± . Why is it so hard to find CP violation? How can B Physics help? Does CP lead beyond the standard model? The author presents a pedestrian symmetry approach which exhibits the difficulties and future possibilities of these two types of CP-violation experiments, neutral meson mixing and direct charge asymmetry: what may work, what doesn't work and why

Determining the global minimum of Higgs potentials via Groebner bases - applied to the NMSSM

International Nuclear Information System (INIS)

Maniatis, M.; Manteuffel, A. von; Nachtmann, O.

2007-01-01

Determining the global minimum of Higgs potentials with several Higgs fields like the next-to-minimal supersymmetric extension of the standard model (NMSSM) is a non-trivial task already at the tree level. The global minimum of a Higgs potential can be found from the set of all its stationary points defined by a multivariate polynomial system of equations. We introduce here the algebraic Groebner basis approach to solve this system of equations. We apply the method to the NMSSM with CP-conserving as well as CP-violating parameters. The results reveal an interesting stationary-point structure of the potential. Requiring the global minimum to give the electroweak symmetry breaking observed in Nature excludes large parts of the parameter space. (orig.)

Minimal flavour violation an effective field theory approach

CERN Document Server

D'Ambrosio, G.; Isidori, G.; Strumia, A.

2002-01-01

We present a general analysis of extensions of the Standard Model which satisfy the criterion of Minimal Flavour Violation (MFV). We define this general framework by constructing a low-energy effective theory containing the Standard Model fields, with one or two Higgs doublets and, as the only source of SU(3)^5 flavour symmetry breaking, the background values of fields transforming under the flavour group as the ordinary Yukawa couplings. We analyse present bounds on the effective scale of dimension-six operators, which range between 1 and 10 TeV, with the most stringent constraints imposed by B -> X_s gamma. In this class of theories, it is possible to relate predictions for FCNC processes in B physics to those in K physics. We compare the sensitivity of various experimental searches in probing the hypothesis of MFV. Within the two-Higgs-doublet scenario, we develop a general procedure to obtain all tan(beta)-enhanced Higgs-mediated FCNC amplitudes, discussing in particular their impact in B -> l^+l^-, Delta...

New LUX and PandaX-II results illuminating the simplest Higgs-portal dark matter models

International Nuclear Information System (INIS)

He, Xiao-Gang; Tandean, Jusak

2016-01-01

Direct searches for dark matter (DM) by the LUX and PandaX-II Collaborations employing xenon-based detectors have recently come up with the most stringent limits to date on the spin-independent elastic scattering of DM off nucleons. For Higgs-portal scalar DM models, the new results have precluded any possibility of accommodating low-mass DM as suggested by the DAMA and CDMS II Si experiments utilizing other target materials, even after invoking isospin-violating DM interactions with nucleons. In the simplest model, SM+D, which is the standard model plus a real singlet scalar named darkon acting as the DM candidate, the LUX and PandaX-II limits rule out DM masses roughly from 4 to 450 GeV, except a small range around the resonance point at half of the Higgs mass where the interaction cross-section is near the neutrino-background floor. In the THDM II+D, which is the type-II two-Higgs-doublet model combined with a darkon, the region excluded in the SM+D by the direct searches can be recovered due to suppression of the DM effective interactions with nucleons at some values of the ratios of Higgs couplings to the up and down quarks, making the interactions significantly isospin-violating. However, in either model, if the 125-GeV Higgs boson is the portal between the dark and SM sectors, DM masses less than 50 GeV or so are already ruled out by the LHC constraint on the Higgs invisible decay. In the THDM II+D, if the heavier CP-even Higgs boson is the portal, theoretical restrictions from perturbativity, vacuum stability, and unitarity requirements turn out to be important instead and exclude much of the region below 100 GeV. For larger DM masses, the THDM II+D has plentiful parameter space that corresponds to interaction cross-sections under the neutrino-background floor and therefore is likely to be beyond the reach of future direct searches without directional sensitivity.

Production and detection at SSC of Higgs bosons in left-right symmetric theories

We discuss the production and detection at SSC of charged and neutral Higgs bosons of the left-right symmetric theories. The H + , which is largely a member of a left-right ''bidoublet,'' should be detectable. The H 2 0 , a more unusual Higgs particle which, apart from mixing, is in a right-handed triplet and does not couple to quarks, may be detectable too

Vortices in superconductors from Lorentz violation

Belich, H.; Orlando, M.T.D.; Costa-Soares, T.; Helayel-Neto, J.A.

2004-01-01

We start from a Lorentz non-invariant Abelian-Higgs model in 1+3 dimensions, and carry out its dimensional reduction to D = 1 + 2. The planar model resulting thereof is composed by a Maxwell-Chern-Simons-Proca gauge sector, a massive scalar sector, and a mixing term (involving the fixed background, v μ ) that realizes Lorentz violation for the reduced model. Vortex type solutions of the planar model are investigated in a superconducting environment . Our vortex solutions are electrically charged and exhibit a screened electric field. (author)

Given the varied backgrounds of the members of this audience this talk will be a grab bag of topics related to the general theme of CP Violation. I do not have time to dwell in detail on any of them. First, for the astronomers and astrophysicists among you, I want to begin by reviewing the experimental status of evidence for CP violation in particle processes. There is only one system where this has been observed, and that is in the decays of neutral K mesons.

We describe a major extension of the SOFTSUSY spectrum calculator to include the calculation of the decays, branching ratios and lifetimes of sparticles into lighter sparticles, covering the next-to-minimal supersymmetric standard model (NMSSM) as well as the minimal supersymmetric standard model (MSSM). This document acts as a manual for the new version of SOFTSUSY, which includes the calculation of sparticle decays. We present a comprehensive collection of explicit expressions used by the program for the various partial widths of the different decay modes in the appendix. Program Files doi:http://dx.doi.org/10.17632/5hhwwmp43g.1 Licensing provisions: GPLv3 Programming language:C++, fortran Nature of problem: Calculating supersymmetric particle partial decay widths in the MSSM or the NMSSM, given the parameters and spectrum which have already been calculated by SOFTSUSY. Solution method: Analytic expressions for tree-level 2 body decays and loop-level decays and one-dimensional numerical integration for 3 body decays. Restrictions: Decays are calculated in the real R -parity conserving MSSM or the real R -parity conserving NMSSM only. No additional charge-parity violation (CPV) relative to the Standard Model (SM). Sfermion mixing has only been accounted for in the third generation of sfermions in the decay calculation. Decays in the MSSM are 2-body and 3-body, whereas decays in the NMSSM are 2-body only. Does the new version supersede the previous version?: Yes. Reasons for the new version: Significantly extended functionality. The decay rates and branching ratios of sparticles are particularly useful for collider searches. Decays calculated in the NMSSM will be a particularly useful check of the other programs in the literature, of which there are few. Summary of revisions: Addition of the calculation of sparticle and Higgs decays. All 2-body and important 3-body tree-level decays, including phenomenologically important loop-level decays (notably, Higgs decays to

Basis-Independent Analysis of the sneutrino Sector in R-Parity Violating Supersymmetry

International Nuclear Information System (INIS)

Grossman, Yuval

2000-01-01

In R-parity-violating supersymmetric models (with a conserved baryon number), there are no quantum numbers that distinguish the lepton-doublet and down-type Higgs supermultiplets. As a result, the R-parity-violating parameters depend on the basis choice for these superfields, although physical observables are independent of the choice of basis. This paper presents a basis-independent computation of the sneutrino/antisneutrino squared-mass splitting in terms of basis-independent quantities. Techniques are developed for an arbitrary number of sneutrino generations; specific results are provided for the one, two and three generation cases

2008-01-01

In grand unified theories (GUT), non-universal boundary conditions for the gaugino masses may arise at the unification scale, and affect the observability of the neutral MSSM Higgs bosons (h/H/A) at the LHC. The implications of such non-universal gaugino masses are investigated for the Higgs boson production in the SUSY cascade decay chain gluino --> squark quark, squark --> neutralino_2 quark, neutralino_2 --> neutralino_1 h/H/A, h/H/A --> b b-bar produced in pp interactions. In the singlet representation with universal gaugino masses only the light Higgs boson can be produced in this cascade with the parameter region of interest for us, while with non-universal gaugino masses heavy neutral MSSM Higgs boson production may dominate. The allowed parameter space in the light of the WMAP constraints on the cold dark matter relic density is investigated in the above scenarios for gaugino mass parameters. We also demonstrate that combination of representations can give the required amount of dark matter in any poi...

Searching for beyond-the-Standard Model Higgs bosons at ATLAS and CMS

Beacham, James; The ATLAS collaboration

2018-01-01

Searches for scalar, Higgs-like particles beyond the Standard Model --- as well as non-standard decays of the newly discovered scalar with a mass of 125 GeV (h125) --- with the ATLAS and CMS detectors at the Large Hadron Collider are presented. Extensions of the SM scalar sector are ubiquitous in new physics scenarios, and motivate a wide variety of experimental searches at the LHC. Signatures mentioned include those sensitive to new higher- or lower- mass scalars or pseudoscalars in two-Higgs doublet models (h/A/H); new particles leading to Vh resonances (where V is a SM vector boson); pair production of h125 from a new, higher-mass particle (di-Higgs); charged Higgs bosons (H+/- or H++/--); lepton flavor violating decays of h125; new, high-mass scalars decaying to V+photon or di-photon final states; exotic decays of h125 to light, intermediate particles that decay to SM final states; and either h125 or new scalars decaying to new long-lived particles that yield atypical detector signatures.

Searches for Higgs and Higgs-like particles at LHCb

Kucharczyk, Marcin

2014-01-01

A set of results related to the new particles searches in LHCb are reported. Upper limits on the cross section times branching fraction of neutral Higgs bos on decaying into two tau leptons have been set in the model independent search and in the Minimal Su persymmetric Model. Many theo- retical models predict the existence of the Higgs bosons dec aying into heavy long-lived particles. The upper limit on their production cross section has been de termined for several combinations of parameters. A measurement of the cross section for the produ ction of b ̄ b and c ̄ c pairs based on in- clusive final states has been performed in a region of pseudor apidity 2.5 5 GeV of the b hadron candidate, resulting in σ ( b ̄ b ) = 7.7 ± 0.12 (stat) ± 0.84 (syst) and σ ( c ̄ c ) = 104.6 ± 2.7 (stat) ± 11.4 (syst). The forward-central b ̄ b production asymme- try, based on the selection of high p T jet pairs tagged by the presence of a displaced muon with high momentum, has been determined to be A b ̄ b FC = (0...

Probing the Randall-Sundrum geometric origin of flavor with lepton flavor violation

International Nuclear Information System (INIS)

Agashe, Kaustubh; Blechman, Andrew E.; Petriello, Frank

2006-01-01

The anarchic Randall-Sundrum model of flavor is a low energy solution to both the electroweak hierarchy and flavor problems. Such models have a warped, compact extra dimension with the standard model fermions and gauge bosons living in the bulk, and the Higgs living on or near the TeV brane. In this paper we consider bounds on these models set by lepton flavor-violation constraints. We find that loop-induced decays of the form l→l ' γ are ultraviolet sensitive and incalculable when the Higgs field is localized on a four-dimensional brane; this drawback does not occur when the Higgs field propagates in the full five-dimensional space-time. We find constraints at the few TeV level throughout the natural range of parameters, arising from μ-e conversion in the presence of nuclei, rare μ decays, and rare τ decays. A tension exists between loop-induced dipole decays such as μ→eγ and tree-level processes such as μ-e conversion; they have opposite dependences on the five-dimensional Yukawa couplings, making it difficult to decouple flavor-violating effects. We emphasize the importance of the future experiments MEG and PRIME. These experiments will definitively test the Randall-Sundrum geometric origin of hierarchies in the lepton sector at the TeV scale

A model of neutrino and Higgs physics at the electroweak scale

International Nuclear Information System (INIS)

Aranda, Alfredo; Blanno, Omar; Diaz-Cruz, J. Lorenzo

2008-01-01

We present and explore the Higgs physics of a model that in addition to the Standard Model fields includes a lepton number violating singlet scalar field. Based on the fact that the only experimental data we have so far for physics beyond the Standard Model is that of neutrino physics, we impose a constraint for any addition not to introduce new higher scales. As such, we introduce right-handed neutrinos with an electroweak scale mass. We study the Higgs decay H→νν and show that it leads to different signatures compared to those in the Standard Model, making it possible to detect them and to probe the nature of their couplings

Supersymmetric Higgs pair discovery prospects at hadron colliders

2000-01-01

We study the potential of hadron colliders in the search for the pair production of neutral Higgs bosons in the framework of the Minimal Supersymmetric Standard Model. Using analytical expressions for the relevant amplitudes, we perform a detailed signal and background analysis, working out efficient kinematical cuts for the extraction of the signal. The important role of squark loop contributions to the signal is emphasised. If the signal is sufficiently enhanced by these contributions, it could even be observable at the next run of the upgraded Tevatron collider in the near future. At the LHC the pair production of light and heavy Higgs bosons might be detectable simultaneously.

T-violation and CPT-invariance measurements in the CPLEAR experiment: a detailed description of the analysis of neutral-kaon decays to eπν

Angelopoulos, A.; Aslanides, E.; Backenstoss, G.

2001-01-01

A detailed description of the analysis of neutral kaons decaying to eπν is given, based on the complete set of data collected with the CPLEAR experiment. Using a novel approach involving initially strangeness-tagged K 0 and K 0 , time-dependent decay-rate asymmetries were measured. These asymmetries enabled T- and CPT-violation parameters to be measured in the context of a systematic study. The highlights of this study are the first direct observation of T violation and the direct determination of the CPT parameter Re(δ) with an accuracy improved by two orders of magnitude with respect to the current value.

BPS Lorentz-violating vortex solutions

Casana, Rodolfo; Ferreira Junior, Manoel M.; Hora, E. da

2011-01-01

In this work, we deal with the construction of static Bogomol'nyi-Prasad-Sommerfield (BPS) rotationally symmetric configurations on the dimensional CPT-even Lorentz-breaking photonic sector of the Standard Model Extension (SME). The main objective of this presentation is to show the possibility of obtaining such BPS solutions, even in the presence of a Lorentz-violating background. A secondary objective is to analyze the effects of this background on such topologically non-trivial BPS configurations. In order to obtain these results, we deal with some specific components of Lorentz-violating field, handling with the static Euler-Lagrange equation of motion to gauge field, from which we fix temporal gauge (absence of electric field) as a proper gauge choice. Also, considering this equation, we consistently determine an interesting configuration (discarding non-interesting ones) to the Lorentz-breaking sector. Using this configuration and the standard rotationally symmetric vortex Ansatz (which describes the behaviors of Higgs and gauge fields via two profile functions, g(r) and a(r), respectively), we construct a rotationally symmetric expression to the energy density of the system. To obtain BPS solutions, we rewrite this expression in order to have static vortex solutions satisfying a set of first order differential equations (BPS ones). The existence of such solutions is strongly constrained by a relation between some parameters of the model, including the Lorentz-breaking one. Naturally, we show that the total energy of these BPS solutions is proportional to their magnetic flux, which is quantized according to their winding number. Using suitable boundary conditions (near the origin and asymptotically), we numerically integrate the BPS equations (by means of the shooting method). By this way, we obtain solutions for some physical quantities (Higgs field, magnetic field and energy density) for several values of the Lorentz-violating parameters. From these

Search for the flavor-changing neutral current interactions of the top quark and the Higgs boson which decays into a pair of b quarks at $\\sqrt{s}=$ 13 TeV

Energy Technology Data Exchange (ETDEWEB)

Sirunyan, Albert M; et al.

2017-12-06

A search for flavor-changing neutral currents (FCNC) in events with the top quark and the Higgs boson is presented. The Higgs boson decay to a pair of b quarks is considered. The data sample corresponds to an integrated luminosity of 35.9 fb$^{-1}$ recorded by the CMS experiment at the LHC in proton-proton collisions at $\\sqrt{s}=$ 13 TeV. Two channels are considered: single top quark FCNC production in association with the Higgs boson (pp $\\to$ tH), and top quark pair production with FCNC decay of the top quark (t $\\to$ qH). Final states with one isolated lepton and at least three reconstructed jets, among which at least two are associated with b quarks, are studied. No significant deviation is observed from the predicted background. Observed (expected) upper limits at 95% confidence level are set on the branching fractions of top quark decays, $\\mathcal{B}$(t $\\to$ uH) $<$0.47% (0.34%) and $\\mathcal{B}$(t $\\to$ cH) $<$ 0.47% (0.44%), assuming a single nonzero FCNC coupling.

A search for flavor-changing neutral currents (FCNC) in events with the top quark and the Higgs boson is presented. The Higgs boson decay to a pair of b quarks is considered. The data sample corresponds to an integrated luminosity of 35.9 fb$^{-1}$ recorded by the CMS experiment at the LHC in proton-proton collisions at $ \\sqrt{s} = $ 13 TeV. Two channels are considered: single top quark FCNC production in association with the Higgs boson (${\\mathrm{p}}{\\mathrm{p}} \\to \\mathrm{t}\\mathrm{H}$), and top quark pair production with FCNC decay of the top quark ($\\mathrm{t} \\to \\mathrm{q}\\mathrm{H}$). Final states with one isolated lepton and at least three reconstructed jets, among which at least two are associated with b quarks, are studied. No significant deviation is observed from the predicted background.

A radiative corrections scheme for generation of the lepton masses

We consider in the context of 331 model of the electroweak interactions the generation of the lepton masses by introducing a single neutral right-handed singlet in a radiatively corrections scheme. By adding a lepton-baryon number violating term in the Higgs potential, we show that one can have the right mass spectrum for the leptons without introducing a sextet of Higgs fields which is present in the original model.

Kobayashi-Maskawa type of hard-CP-violation model with three-generation Majorana neutrinos

International Nuclear Information System (INIS)

Cheng, H.

1986-01-01

Within the framework of the Kobayashi-Maskawa (KM) type of hard CP-violation model with three-generation Majorana neutrinos, we point out that on-shell CP-violation phenomena (i.e., CP-violating effects taking place in on-shell processes), which are characteristic of Majorana neutrinos, can only occur in total-lepton-number-conserving reactions, and are unobservably small. Off-shell CP-nonconserving effects which arise from gauge bosons are undetectable, but those which are mediated by Higgs bosons could be seen in certain rare decays. It is emphasized that CP-odd effects intrinsic to Majorana behavior depend not only on the two CP-violating Majorana phases but also on the KM phase. We then demonstrate why the KM model, which has rich implications in the hadronic sector, leads to no observable CP-violating effects in leptonic processes (except in neutrino oscillations) directly related to the CP-odd KM phase

In Higgs-otic inflation a complex neutral scalar combination of the h{sup 0} and H{sup 0} MSSM Higgs fields plays the role of inflaton in a chaotic fashion. The potential is protected from large trans-Planckian corrections at large inflaton if the system is embedded in string theory so that the Higgs fields parametrize a D-brane position. The inflaton potential is then given by a DBI+CS D-brane action yielding an approximate linear behaviour at large field. The inflaton scalar potential is a 2-field model with specific non-canonical kinetic terms. Previous computations of the cosmological parameters (i.e. scalar and tensor perturbations) did not take into account the full 2-field character of the model, ignoring in particular the presence of isocurvature perturbations and their coupling to the adiabatic modes. It is well known that for generic 2-field potentials such effects may significantly alter the observational signatures of a given model. We perform a full analysis of adiabatic and isocurvature perturbations in the Higgs-otic 2-field model. We show that the predictivity of the model is increased compared to the adiabatic approximation. Isocurvature perturbations moderately feed back into adiabatic fluctuations. However, the isocurvature component is exponentially damped by the end of inflation. The tensor to scalar ratio varies in a region r=0.08–0.12, consistent with combined Planck/BICEP results.

Diphoton and diboson probes of fermiophobic Higgs bosons at the LHC

International Nuclear Information System (INIS)

Delgado, Antonio; Garcia-Pepin, Mateo; Quirós, Mariano; Santiago, José; Vega-Morales, Roberto

2016-01-01

Extensions of the Standard Model Higgs sector with electroweak charged scalars can possess exotic ‘Higgs’ bosons with vanishing or suppressed couplings to Standard Model fermions. These ‘fermiophobic’ scalars, which cannot be produced via gluon fusion, are constrained by LHC measurements of the 125 GeV Higgs boson to have a small vacuum expectation value. This implies that vector boson fusion and associated vector boson production are in general suppressed rendering conventional Higgs searches insensitive. However, Drell-Yan Higgs pair production, which is not present in the SM, can be sizeable even in the limit of vanishing exotic Higgs vacuum expectation value. We utilize this to show that diphoton searches at 8 TeV LHC already rule out a large class of neutral fermiophobic Higgs bosons below ∼110 GeV. This includes fermiophobic scalars found in two Higgs doublet as well as Higgs triplet and Georgi-Machacek type models. Our results extend the only relevant limit on fermiophobic Higgs bosons obtained by a recent CDF analysis of 4γ+X Tevatron data. Furthermore, diphoton limits are independent of the decay of the second Higgs boson and thus apply even for degenerate masses in contrast to the CDF search. We also find that if the fermiophobic Higgs has very enhanced couplings to photons, masses as large as ∼150 GeV can be ruled out while if these couplings are somehow highly suppressed, masses below ∼90 GeV can still be ruled out. Finally, we show that WW and ZZ diboson searches may serve as complementary probes for masses above the diphoton limit up to ∼250 GeV and discuss prospects at 13 TeV LHC.

Neutrino Masses from Neutral Top Partners

CERN Document Server

Batell, Brian

2015-01-01

We present theories of `Natural Neutrinos' in which neutral fermionic top partner fields are simultaneously the right-handed neutrinos (RHN), linking seemingly disparate aspects of the Standard Model structure: a) The RHN top partners are responsible for the observed small neutrino masses, b) They help ameliorate the tuning in the weak scale and address the little hierarchy problem, and c) The factor of $3$ arising from $N_c$ in the top-loop Higgs mass corrections is countered by a factor $3$ from the number of vector-like generations of RHN. The RHN top partners may arise in pseudo-Nambu-Goldstone-Boson (pNGB) Higgs models such as the Twin Higgs, as well as more general Composite, Little, and Orbifold Higgs scenarios, and three simple example models are presented. This framework firmly predicts a TeV-scale seesaw, as the RHN masses are bounded to be below the TeV scale by naturalness. The generation of light neutrino masses relies on a collective breaking of lepton number, allowing for comparatively large ne...

Masses, flavor mix and CP violation

International Nuclear Information System (INIS)

Chaussard, L.

2004-06-01

The author describes the relationships between masses, mixing of flavors and CP violation. This document is divided into 4 chapters: 1) fermions' masses, 2) mixing of flavors and CP violation, 3) beauty physics and 4) neutrino physics. In chapter 1 an attempt is made to explain what is behind the concepts of lepton mass and quark mass. As for neutrinos, the only neutral fermion, Dirac's and Majorana's views are exposed as well as their consequences. Fermion flavors are mixed in the process of mass generation and this mix is responsible for the breaking of CP and T symmetries. In chapter 2 the author shows how the analysis of particle oscillations from neutral mesons (K 0 , D 0 , B d 0 and B s 0 ) and from neutrinos can shed light on CP violation. Chapter 3 is dedicated to the contribution of beauty physics to the determination of the unitary triangle, through the oscillations of beauty mesons. In chapter 4 the author reviews the experimental results obtained recently concerning neutrino mass and neutrino oscillations and draws some perspectives on future neutrino experiments. (A.C.)

Charged Higgs boson searches and SemiConductor Tracker commissioning for the ATLAS experiment

CERN Document Server

Mohn, Bjarte Alsaker

The ATLAS (A Toroidal Lhc ApparatuS) experiment is one of four major experiments presently being installed at the upcoming Large Hadron Collider (LHC) at the European Centre for Nuclear Research (CERN) outside Geneva. In this thesis we present work done on both the simulation of the ATLAS physics potential for a charged Higgs boson and the construction of the Semiconductor Tracker (SCT) - a subdetector within the ATLAS Inner Detector. The discovery of a charged Higgs boson would be an unambiguous sign of physics beyond the Standard Model (SM) and it is thus of great interest to study the ATLAS potential for a charged Higgs discovery. Two such studies have been conducted for this thesis. In the first study a large-mass-splitting Minimal Supersymmetric Standard Model (MSSM) is assumed in which the charged Higgs boson decays into a W boson and a neutral Higgs may receive a large branching ratio.We conclude, however, that charged Higgs searches in this decay channel are made difficult by a large irreducible SM ba...

Neutral Higgs boson searches in the H→ττ→μμ decay channel

International Nuclear Information System (INIS)

Bethani, Agni

2013-10-01

This dissertation describes the search for Higgs bosons decaying to a pair of τ leptons both decaying to muons. The analysis was performed using events recorded by the CMS detector at the LHC in 2011 and 2012, at center-of-mass energy 7 TeV and 8 TeV respectively. The dataset corresponds to total integrated luminosity of 17 fb -1 , 4.9 fb -1 taken at 7 TeV center-of-mass energy and 12.1 fb -1 at 8 TeV. The results were interpreted in the context of both the Standard Model and the Minimal Supersymmetric Standard Model. Upper limits were set to the Higgs production cross section in the former case and on the (tan β, m A ) plane in the latter. The update of this analysis with more data, combined with other ττ final states, lead to the first evidence of the Higgs coupling to τ leptons. Included in this document is also the study of the Z boson production followed by Z → ττ decay with two muons in the final state. This analysis was performed with 36 pb -1 of data collected in 2010, at center-of-mass energy 7 TeV, by the CMS experiment. The result of this study was the measurement of the Z production cross section in proton-proton collisions. The analysis procedures developed for the Z boson decay to τ leptons were used to commission the Higgs boson searches in the same decay channel.

Applying exclusion likelihoods from LHC searches to extended Higgs sectors

2015-01-01

LHC searches for non-standard Higgs bosons decaying into tau lepton pairs constitute a sensitive experimental probe for physics beyond the Standard Model (BSM), such as supersymmetry (SUSY). Recently, the limits obtained from these searches have been presented by the CMS collaboration in a nearly model-independent fashion - as a narrow resonance model - based on the full 8 TeV dataset. In addition to publishing a 95 % C.L. exclusion limit, the full likelihood information for the narrowresonance model has been released. This provides valuable information that can be incorporated into global BSM fits. We present a simple algorithm that maps an arbitrary model with multiple neutral Higgs bosons onto the narrow resonance model and derives the corresponding value for the exclusion likelihood from the CMS search. This procedure has been implemented into the public computer code HiggsBounds (version 4.2.0 and higher). We validate our implementation by cross-checking against the official CMS exclusion contours in three Higgs benchmark scenarios in the Minimal Supersymmetric Standard Model (MSSM), and find very good agreement. Going beyond validation, we discuss the combined constraints of the ττ search and the rate measurements of the SM-like Higgs at 125 GeV in a recently proposed MSSM benchmark scenario, where the lightest Higgs boson obtains SM-like couplings independently of the decoupling of the heavier Higgs states. Technical details for how to access the likelihood information within HiggsBounds are given in the appendix. The program is available at http:// higgsbounds.hepforge.org. (orig.)

Exotic Higgs decays in a neutrino mass model with discrete S3 symmetry

CERN Document Server

Bhattacharyya, G; Päs, H

2010-01-01

Exotic Higgs decays can arise in lepton flavor models with horizontal symme- tries. We investigate the scalar sector of a neutrino mass model using an S3 family symmetry as an example. The model’s symmetry leads to an enlarged scalar sector with features that might be used to test the model experimentally, such as scalar particles with masses below 1 TeV and manifestly non-zero ma- trix elements for lepton flavor violating decays. We compare different decay channels of the scalars as well as leptonic processes that violate lepton flavor, in order to compare model predictions with experimental bounds.

Using the QCD factorization approach, we investigate the large branching ratios of B →φ K s decays and tjhe S φKs anomaly of B →K s decay in the two Higgs doublet model III. With the contributions of flavour-changing neutral current mediated by the neutral Higgs bosons H 0 , h 0 and A 0 at the tree level, we provide a coherent resolution to these anomalies within the constrained parameter spaces, which are 120 bs λ ss | <136. This will be really interesting in searching for the signs of new physics. (the physics of elementary particles and fields)

Cosmological Constraints on Decoupled Dark Photons and Dark Higgs

Any neutral boson such as a dark photon or dark Higgs that is part of a non-standard sector of particles can mix with its standard model counterpart. When very weakly mixed with the Standard Model, these particles are produced in the early Universe via the freeze-in mechanism and subsequently decay back to standard model particles. In this work, we place constraints on such mediator decays by considering bounds from Big Bang nucleosynthesis and the cosmic microwave background radiation. We find both nucleosynthesis and CMB can constrain dark photons with a kinetic mixing parameter between log ϵ ~ -10 to -17 for masses between 1 MeV and 100 GeV. Similarly, the dark Higgs mixing angle ϵ with the Standard Model Higgs is constrained between log ϵ ~ -6 to -15. Dramatic improvement on the bounds from CMB spectral distortions can be achieved with proposed experiments such as PIXIE.

The MSSM Parameter Space with Non-Universal Higgs Masses

CERN Document Server

Ellis, Jonathan Richard; Santoso, Y; Ellis, John; Olive, Keith A.; Santoso, Yudi

2002-01-01

Without assuming that Higgs masses have the same values as other scalar masses at the input GUT scale, we combine constraints on the minimal supersymmetric extension of the Standard Model (MSSM) coming from the cold dark matter density with the limits from direct searches at accelerators such as LEP, indirect measurements such as b to s gamma decay and the anomalous magnetic moment of the muon. The requirement that Higgs masses-squared be positive at the GUT scale imposes important restrictions on the MSSM parameter space, as does the requirement that the LSP be neutral. We analyze the interplay of these constraints in the (mu, m_A), (mu, m_{1/2}), (m_{1/2}, m_0) and (m_A, tan beta) planes. These exhibit new features not seen in the corresponding planes in the constrained MSSM in which universality is extended to Higgs masses.

The data collected by the OPAL experiment at sqrts=183 GeV were used to search for Higgs bosons which are predicted by the Standard Model and various extensions, such as general models with two Higgs field doublets and the Minimal Supersymmetric Standard Model (MSSM). The data correspond to an integrated luminosity of approximately 54pb-1. None of the searches for neutral and charged Higgs bosons have revealed an excess of events beyond the expected background. This negative outcome, in combination with similar results from searches at lower energies, leads to new limits for the Higgs boson masses and other model parameters. In particular, the 95% confidence level lower limit for the mass of the Standard Model Higgs boson is 88.3 GeV. Charged Higgs bosons can be excluded for masses up to 59.5 GeV. In the MSSM, mh > 70.5 GeV and mA > 72.0 GeV are obtained for tan{beta}>1, no and maximal scalar top mixing and soft SUSY-breaking masses of 1 TeV.

Lattice gauge fixing as quenching and the violation of spectral positivity

International Nuclear Information System (INIS)

Aubin, C.; Ogilvie, Michael C.

2004-01-01

Lattice Landau gauge and other related lattice gauge-fixing schemes are known to violate spectral positivity. The most direct sign of the violation is the rise of the effective mass as a function of distance. The origin of this phenomenon lies in the quenched character of the auxiliary field g used to implement lattice gauge-fixing, and is similar to quenched QCD in this respect. This is best studied using the Parrinello Jona-Lasinio Zwanziger formalism, leading to a class of covariant gauges similar to the one-parameter class of covariant gauges commonly used in continuum gauge theories. Soluble models are used to illustrate the origin of the violation of spectral positivity. The phase diagram of the lattice theory, as a function of the gauge coupling β and the gauge-fixing parameter α, is similar to that of the unquenched theory, a Higgs model of a type first studied by Fradkin and Shenker. The gluon propagator is interpreted as yielding bound states in the confined phase, and a mixture of fundamental particles in the Higgs phase, but lattice simulation shows the two phases are connected. Gauge-field propagators from the simulation of an SU(2) lattice gauge theory on a 20 4 lattice are well described by a quenched mass-mixing model. The mass of the lightest state, which we interpret as the gluon mass, appears to be independent of α for sufficiently large α

The arguments favouring gravitation as the 'Master Arrow of Time' are briefly reviewed and the possibility that CP violation observed in the neutral kaon system may be explained by a violation of the Equivalence Principle is discussed. It was attempted to demonstrate that the arguments against antigravity should be reconsidered and that the neutral kaon system, the most sensitive interferometric system at the disposal, is ideal to test the existence of antigravity.
