| Outline of Final Research Achievements |
Performing the detailed analysis of neutrino oscillation, we showed that the degeneracy of the mass hierarchy, θ23, CP phase δ, and non-standard interactions can be determined. In the search for lepton flavor breaking, we found that the angular distribution of the emitted electrons can be used to determine the shape of the interaction. The process with the lepton and baryon number violations is shown to occur at observable levels that are consistent with other experiments, depending on the symmetry of the theory at high energies. By taking the systematic approach for neutrino mass models in terms of new particle interactions, a new mass model for the Dirac neutrino, which has not received much attention, is discovered.
