The ability of future e+e− colliders to study the supersymmetric Higgs sector is examined. The effects of the radiative corrections are included. A global analysis is given for the production cross-sections of the neutral Higgs bosons over the full parameter space of the Higgs sector, which clarifies the integrated luminosity necessary for the detection of the neutral Higgs bosons. The branching ratios of the three neutral Higgs bosons are also computed.

The Cross

We studied the production of charginos and neutrilinos associated with Higgs and gauge bosons in the Minimal Supersymmetric Standard Model (MSSM) at linear colliders. Understanding the processes will help determine the couplings of charginos and neutralinos to Higgs and gauge bosons in the MSSM. We investigated the parameter space for values of μ between –2000 and 2000 GeV and values of M2 between 0 and 2000 GeV. We found that the cross sections of the processes reach only a few femtobarns at a e+e– colliders with [Formula: see text] GeV.

This study presents an overview of the potential of the ATLAS detector at LHC for the observation of the Higgs boson of the minimal supersymmetric Standard Model (MSSM). The expected rates, backgrounds and significances are discussed channel by channel using realistic assumptions for the detector performance. As final results, the ranges of the MSSM parameter space projected on the (mA, tan β) and (mh, tan β) planes, for which the expected significances for the discovery of the different channels exceed a 5σ value, are shown for the ATLAS detector alone and for combined results from the ATLAS and CMS detectors. It is concluded that the combined potential of the two LHC detectors should fully cover the Higgs sector of the MSSM parameter space. The sensitivity of the results to the upper limit of the allowed mass for the lightest Higgs boson is extensively discussed. The direct impact of the SUSY particle sector on such searches is neglected in this paper.

Effective Operators

Possible realistic scenarios are investigated in the minimal supersymmetric standard model (MSSM) Higgs sector extended by dimension-six effective operators. The CP-odd Higgs boson with low mass around 30–90 GeV could be consistently introduced in the regime of large threshold corrections to the effective MSSM two-doublet Higgs potential.

The theoretical structure of the Higgs sector of the Minimal Supersymmetric Standard Model (MSSM) is briefly described. An outline of Higgs phenomenology at future lepton colliders is presented, and some opportunities for probing the physics of the MSSM Higgs sector at an e-e- collider are considered.

The observation of [Formula: see text] at present experiments would be a clear sign of new physics. In this paper, we calculate this process in an extended Higgs sector framework where the decay is mediated by the exchange of spin zero particle with flavor changing neutral current couplings. If we identify the scalar with the newly discovered state at LHC with a mass ~125 GeV then we find that, after imposing all experimental constraints, the [Formula: see text] can be as high as ~10-6 and [Formula: see text] can be as high as ~10-7. We also calculate this process in the minimal supersymmetric standard model and find the [Formula: see text] is typically of the order ~10-8.
