Outline of Final Research Achievements

Although the Higgs boson was discovered, the essence of the Higgs boson and the structure of the Higgs sector remain unknown. Based on the idea that the Higgs sector is the window for new physics beyond the standard model, we have performed theoretical studies on various extended Higgs sectors in order to determine the essence of the Higgs boson and the structure of the Higgs sector by utilizing the current and future collider data from the LHC and the International Linear Collider. We have obtained the new results for the following subjects. 1) Phenomenological studies for the determination of the structure of the Higgs sector by using future collider experiments, 2) Theoretical studies on the essence of the Higgs boson and on the more fundamental physics behind the Higgs sector, 3) Model building to explain the phenomena which cannot be explained in the standard model, such as tiny neutrino masses, dark matter and baryon asymmetry of the Universe.
