Description

The origin of tiny neutrino masses, dark matter, and baryon asymmetry of the universe is still a mystery, and there is no doubt that there is new physics beyond the Standard Model. In a previous work, a new physics model at TeV-scale where all of them can be explained has been proposed, however the authors neglected CPV phases, and on the baryon asymmetry, they only showed the possibility of the strongly 1st order phase transition for the electroweak baryogenesis. We have extended this model to include CPV phases and evaluated neutrino masses, dark matter, and the baryon number asymmetry generated by the electroweak baryogenesis. In this talk, I will introduce this model and discuss the phenomenology at current and near future experiments including the ILC.
