Outline of Final Research Achievements

We studied flavor physics in physics beyond the standard model. Rare processes, such as lepton-flavor violating processes, and also electric dipole moments are sensitive to beyond the standard model. We showed the relations between the observables and the fundamental parameters in the models, and gave constraints on the models including supersymmetric models and extended Higgs models by combining the results of Higgs measurements and new particle searches at LHC. We also discussed the electroweak baryogeneis in the extended Higgs models. We constructed realistic grand unified models based on the LHC results, and predicted the proton decay rates. We also constructed realistic models to predict quark and lepton masses, and discussed leptogenesis in the models.
