This review starts with a brief introduction to the charged Higgs boson (H±) in the Minimal Supersymmetric Standard Model (MSSM). It then discusses the prospects of a relatively light H± boson search via top quark decay at Tevatron/LHC, and finally a heavy H± boson search at LHC. The viable channels for H± search are identified in both the cases, with particular emphasis on the H±→τν decay channel. The effects of NLO QCD correction in the SM as well as the MSSM are discussed briefly.

The results of the QCD corrections to the [Formula: see text] decay within the minimal super-symmetric standard model such that gluinos and scalar quarks are taken within the relevant loop diagram are presented. The mixing of the scalar partners of the left- and right-handed top quarks which is proportional to the top quark mass is included. The standard corrections via gluons and quarks are about +7% for a charged Higgs mass of 300 GeV and about −10% for a Higgs mass of 800 GeV. The standard corrections can be shown to diminish or enhance by a non-negligible amount of certain values of the supersymmetric parameter space. The sign changes can also be obtained.

One loop mediated charged Higgs bosons decays H± → W±V, V = Z, γ are studied in the Minimal Supersymmetric Standard Model (MSSM) with and without CP violating phases. We evaluate the MSSM contributions to these processes taking into account B → Xsγ constraint as well as experimental constraints on the MSSM parameters. In the MSSM, we found that in the intermediate range of tan β ≲ 10 and for large At and large μ, where the lightest top squark becomes very light and hence non-decoupled, the branching ratio of H± → W±Z can be of the order 10−3 while the branching ratio of H± → W±γ is of the order 10−5. We found also that the CP violating phases of soft SUSY parameters can modify the branching ratio by about one order of magnitude. We also show that MSSM with CP violating phases lead to CP-violating asymmetry in the decays H+ → W+V and H− → W−V. Such CP asymmetry can be rather large and can reach 80% in some region of parameter space.

We compute the baryon asymmetry generated at the electroweak phase transition by the Higgs scalar sector of the minimal supersymmetric standard model. Because of large enhancement effects from low momentum modes, Higgs particles may be responsible for the observed baryon asymmetry even though CP-violation in the Higgs sector only appears at the one-loop level. We also discuss the approximations made in the analysis and suggest possible improvements.

Focus Point

We investigate the focus points of the renormalization group equations of the minimal supersymmetric standard model. We show that within this model the up- and down-type Higgs mass soft supersymmetry breaking parameters have focus point behavior at the electroweak scale simultaneously when appropriate conditions are fulfilled. The focus point scenario holds for large tan β. This two-focus-point scenario allows to fix the pole top-quark mass which is within the experimentally allowed interval. The main goal of this paper is the investigation of the influence of the existence of focus points on the determination of the mass of the lightest Higgs boson.
