Light Stop, Heavy Higgs, and Heavy Gluino in Supersymmetric Standard Models with Extra Matters

Abstract

We have explored the possibilities of scenarios with heavy gluinos and light stops in the supersymmetric (SUSY) standard models with extra vector-like multiplets. If we assume the hierarchical structure for soft masses of the minimal supersymmetric standard model (MSSM) scalar fields and extra scalars, the light stop and the observed Higgs boson can be realized. In the context of the gaugino mediation, naturally these hierarchy for soft mass are created and the FCNC processes are suppressed. While the stau is the lightest SUSY particle (LSP) in broad parameter space, we have found the neutralino LSP is realized in the case that the non-zero soft parameters for the MSSM Higgs doublets or the non-universal gaugino masses are assumed.
