| Research Abstract |
We studied possible theoretical frameworks beyond the standard model and their phenomenological features on the basis of both neutrino masses and dark matter which were found through various recent experiments and observations. We clarified the quantitative relation between nature of neutrinos such as masses and mixing and nature of dark matter which appears in the relic abundance, direct and indirect searches. We extended the model to be supersymmetric and suggested that there appears two types of dark matter. Their nature was analyzed in the quantitative way. We also studied the baryon number asymmetry in the universe in these models.
