Higgs boson mass and muon g-2 with strongly coupled vector-like generations

Supersymmetry (SUSY) is one of the most attractive candidates for the theory beyond the Standard Model (SM). Among them, the minimal supersymmetric extension to the SM (MSSM) has been studied in detail. In the MSSM, it is difficult to explain the Higgs boson mass and the muon anomalous magnetic moment (the muon g-2) simultaneously for universal SUSY-breaking parameters, e.g. the minimal supergravity mediation. In this talk, to above problem, we introduce the effect of extra vector-like generations. As the important feature of this model, we discuss the infrared fixed point behavior. That leads to sizable extra Yukawa couplings of Higgs doublets between the second and vector-like generations in both quark and lepton sectors.
