Flavor structure, Higgs boson mass and dark matter in supersymmetric model with vector-like generations

Understand

We study a supersymmetric model in which the Higgs mass, the muon anomalous magnetic moment and the dark matter are simultaneously explained with extra vector-like generation multiplets.

• For the explanations, non-trivial flavor structures and a singlet field are required.
• In this paper, we study the flavor texture by using the Froggatt-Nielsen mechanism, and then find realistic flavor structures which reproduce the Cabbibo-Kobayashi-Maskawa matrix and fermion masses at low energy.
• Furthermore, we find that the fermion component of the singlet field becomes a good candidate of dark matter.
