| Outline of Final Research Achievements |
We proposed ``flaxion model”. This model not only explains the hierarchical flavor structure in the quark and lepton sector (including the neutrino sector), but also solves the strong CP problem as well as the Dark Matter puzzle. Moreover, the model can also explain the inflation and the cosmological baryon asymmetry in the Universe.
We also studied comprehensively the constraints and future prospects of the search for Higgs- and Z-resonant O(10 GeV) neutralino dark matter in supersymmetric models. It was shown that almost all the parameter space of the scenario will be probed complementarily by the collider search and the direct detection experiments.
We also conducted several other theoretical researches on Dark Matter.
