| Outline of Final Research Achievements |
The discovery of the Higgs particle at the LHC in 2012 filled the last gap of the Standard Model of the elementary particle physics. On the other hand, no symptom of the new physics has been seen. The discovered Higgs mass strongly suggests the criticality of the Higgs potential in the Standard Model, that is, the Higgs potential in the Standard Model becomes flat at very high scales. Given this situation, I have proposed a scenario where the Higgs potential in the Standard Model in the criticality is not altered up to very high scales and the Higgs field causes the cosmological inflation, and have studied its phenomenology. I have shown that the large Higgs field limit in the superstring theory opens up an extra dimension.
