چکیده

We discuss the observability of the lightest neutral Higgs boson in the constrained MSSM (CMSSM), with universal soft supersymmetry-breaking parameters, at hadron colliders such as the Tevatron and the LHC. We take account of the constraints on parameter space provided by LEP, the measured rate of b → sγ decay, the cosmological relic density Ωχh , and the recent measurement of gμ − 2. We normalize products of the expected CMSSM Higgs production cross sections and decay branching ratios σ × B relative to those expected for a Standard Model Higgs boson of the same mass. In the h → γγ channel, we find that [ σ(gg → h)×B(h → γγ) ]

The lightest Higgs Boson of mSUGRA, mGMSB and mAMSB at Present and Future Colliders: Observability and Precision Analyses

We investigate the physics of the lightest CP-even MSSM Higgs boson at the Tevatron, the LHC, a linear e+e− collider, a γγ collider and a μ+μ− collider. The analysis is performed in the three most prominent soft SUSY-breaking scenarios, mSUGRA, mGMSB and mAMSB. For all colliders the observability and parameter regions with suppressed production cross sections (compared to a SM Higgs boson with ...

Higgs Boson Production in Association with Scalar Top Quarks at Proton Colliders

We investigate the production of Higgs particles in association with the supersymmetric scalar partners of the top quark at proton colliders. In the minimal supersymmetric extension of the Standard Model, the cross sections for the production of the lightest neutral Higgs boson in association with top squark pairs can be rather large, substantially exceeding the rate for the associated Higgs bo...

Precision Analysis of the Lightest MSSM Higgs Boson at Future Colliders

We investigate the sensitivity of observables measurable in e+e−, γγ and μ+μ− 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 s...

Observability of the Lightest MSSM Higgs Boson with Explicit CP Violation via Gluon Fusion at the LHC

We investigate the observability of the lightest Higgs boson in the gluon–fusion channel at the CERN Large Hadron Collider (LHC) in the minimal supersymmetric Standard Model with explicit CP–violating mixing among three neutral Higgs bosons. The lightest Higgs boson with its mass less than 130 GeV can be detected at the LHC via its gluon–fusion production followed by the decay into two photons....

Distributions for MSSM Higgs boson + jet production at hadron colliders

We present pseudorapidity and transverse momentum distributions for the cross section for the production of the lightest neutral Higgs boson in association with a high-pT hadronic jet, calculated in the framework of the minimal supersymmetric standard model (MSSM). We discuss the theoretical predictions for the differential cross sections at the Large Hadron Collider and the Tevatron for the mo...
