Outline of Final Research Achievements

After the discovery of the Higgs particle in 2012, researchers, including ourselves, revealed that the Standard Model of particle physics can be theoretical consistent up to the Planck scale, which is quadrillion times larger than the currently observed TeV scale. On the other hand, the success of the Standard Cosmology has made certain that we need physics beyond the Standard Model such as the dark matter and the inflation. Under this situation, we have proposed the critical Higgs inflation, in which the Higgs field causes the inflation, and studied various physical consequences.
