Outline of Final Research Achievements

We discussed precision of the future long baseline experiments HK and DUNE, and showed that we can solve the degeneracies of hierarchy and octant. We discussed the sensitivity of HK, DUNE, T2HKK to the non-standard interactions, its dependence on the systematic errors and on the off-axis angle of the T2HKK, and we gave some insight on the future project. We also found new degeneracy which arises from the new CP phase in the presence of light sterile neutrinos. We proposed a new model which accounts for the IceCube Gap and the anomalous magnetic moment of muons and discussed its phenomenology, and discussed the possibility to discover lepton flavor violating processes at Bell-II, COMET, LHC, ILC.
