| Outline of Final Research Achievements |
I have analyzed the vacuum structure of scalar potentials in supersymmetric models and showed the existance of some new vacua. Such new vacua include so-called false vacua on which the Universe we live is never realized. I derived the conditions to avoid the false vacua and gave new constraints on the parameters of supersymmetry breaking terms, Higgs mass terms and neutrino mass terms. Especially, based on latest data reported from the LHC experiment, I have analyzed the vacuum structure of the Next-to-Minimal Supersymmetric Standard Model implementing the Mirage mediation, which can explain the mass of the Higgs particle, and gave constraints on the supersymmetry breaking parameters.
