*Spontaneous CP violation in E6 SUSY GUT with SU(2) flavor and anomalous U(1) symmetries(*) Reviewed

Language：English   Publishing type：Research paper (scientific journal)  

We showed that in E6 grand unified theory with family symmetry, spontaneous CP violation can not only solve the SUSY CP problem but also realize reasonable Kabayashi-Maskawa phase. I think that this scenario is one of the most promizing scenario which explains the origin of the Kobayashi-Maskawa matrix.

Lepton flavor violation in SUSY GUT model with non-universal sfermion masses Reviewed

In E6 grand unified theory with horizontal symmetry, a specific sfermion mass spectrum is predicted. In this paper, we calculated the lepton flavor violation processes predicted by the sfermion mass spectrum. We pointed out that tau->mu gamma can be observed in (super) B factory and mu-> e gamma in MEG experiment.

Solution for little hierarchy problem and b-> s gamma Reviewed

When the standard model Higgs mass bound obtained by LEP is applied to the Higgs in supersymmetric models, the electroweak scale becomes unstable because of the large stop mass. This is called the little hierarchy problem. We pointed out that in the minimal supersymmetric standard model, there is a parameter region in which the coupling between the lightest higgs and Z boson becomes smaller than in the standard model and the higgs mass bound cannot be applied. We also pointed out that in the parameter region, all the Higgs bosons become light, but the contribution to the b->s gamma process can be cancelled by supersymmetric contribution.
