| Outline of Final Research Achievements |
We discussed the possibility of resolving degeneracy of the mass hierarchy in the near future long baseline experiments such as the phase 2 T2K and Nova experiments. We extended the Kimura-Takamura-Yokomakura formulation, which was developed to obtain the analytic expression for the neutrino oscillation probability in the case with constant matter density, to the case where the matter density varies nonadiabatically and oscillations are averaged over. We discussed the constraint from the Superkamiokande atmospheric neutrino data on the nonstandard scenario of sterile neutrinos, which feel matter effect much larger than the standard case. We discussed the constraint from the Superkamiokande atmospheric neutrino data on and the sensitivity of the future Hyperkamiokande atmospheric neutrino experiment to the electron and tau components of the nonstandard interaction in the neutrino propagation, assuming the knwon constraint from the high energy atmospheric neutrino data.
