| Outline of Final Research Achievements |
We have studied some extended theoretical frameworks of the standard model from a view point that neutrino masses, dark matter abundance and baryon number asymmetry in the Universe should be explained in them, simultaneously. As such an interesting extension, we have adopted radiative neutrino mass models which are constructed by introducing new scalar fields to the standard model. We have examined the neutrino masses and mixing, the dark matter abundance and the generation of baryon number asymmetry in the model to find that they could be explained consistently. We have also shown that the model could realize inflation which is consistent with the data obtained through CMB observations.
