Outline of Final Research Achievements

In the SM, the Higgs mass of 125 GeV suggests that Higgs potential becomes unstable around 10^10 GeV. The SM framework alone does not realize vanishing Higgs potential at the Planck scale with the classical scale invariance. Concentrating on it, we can predict the magnitudes of dark matter and Majorana masses of right-handed neutrinos. We also construct a model that realize weak phase transition through the Bosonic seesaw mechanism with a strongly coupled dynamics, and obtained experimental predictions. We also construct a new model of explaining the origins of tiny neutrino masses or parity violation, and investigated its observability in experiments.
