MSSM Higgs bosons associated with high-pT jets at hadron colliders
نویسندگان
چکیده
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), is presented. The expectations for the hadronic cross section at the Large Hadron Collider are discussed using reasonable kinematical cuts. In particular the contributions from superpartner loops to the cross section and their dependence on the parameters of the MSSM are investigated and found to be significant. Comparisons show that the production rate for h0 + jet in the MSSM can differ widely from the corresponding standard-model prediction. E-mail: [email protected] E-mail: [email protected]

Distributions for Higgs + jet at hadron colliders: MSSM vs SM
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. We discuss the theoretical predictions for the differential cross sections at the Large Hadron Collider and the Tevatron. In particular, w...
متن کاملCP-violating MSSM Higgs at Tevatron and LHC
We analyze the prospect for observing the intermediate neutral Higgs boson (h2) in its decay to two lighter Higgs bosons (h1) at the presently operating hadron colliders in the framework of the CP violating MSSM using the PYTHIA event generator. We consider the lepton+ 4-jets+ E/T channel from associate Wh2 production, with Wh2 → Wh1h1 → lνlbb̄bb̄. We require two or three tagged b-jets. We explic...

متن کاملProbing the Higgs self-coupling at hadron colliders using rare decays
We investigate Higgs boson pair production at hadron colliders for Higgs boson masses mH<140 GeV and the rare decay of one of the two Higgs bosons. While in the standard model the number of events is quite low at the CERN Large Hadron Collider ~LHC!, a first, albeit not very precise, measurement of the Higgs boson self-coupling is possible in the gg→HH→bb̄gg channel. A luminosity-upgraded LHC co...
متن کاملImpact of the Susy Decays on the Search for the Mssm Higgs Bosons at the Lhc
In the context of the Minimal Supersymmetric extension of the Standard Model, we discuss the impact of the decays of the neutral Higgs bosons into supersymmetric particles, charginos/neutralinos and sfermions. We show that these decay modes could be dominant, when they are kinematically accessible, thus strongly suppressing the branching ratios for the decay channels which are used to detect th...
