Outline of Final Research Achievements

The discovery of the Higgs particle with 125 GeV mass at the LHC experiment has a great impact on the establishment of the standard model of particle physics, the directions beyond the standard model, and cosmology based on it. We have investigated, in the light of the discovery of the Higgs particle, the influences on the model buildings of supersymmetric standard models, the inflation models driven by the Higgs boson, the dark radiaton of the Universe in the Higgs portal models, and the cosmological implications of the supersymmetric Peccei-Quinn models and so on.
