Research Abstract

We have investigated new physics beyond the Standard Model explaining neutrino masses, dark matter and baryon asymmetry of the universe. In particular, the extension by right-handed neutrinos with masses smaller than the electroweak scale has been considered. We have discussed baryogenesis by right-handed neutrino oscillations and the direct searches of right-handed neutrinos.
