Outline of Final Research Achievements

Now that we have gained the knowledge on the neutrino flavor mixing in the standard scenario, attention is being focused on new physics which can be probed by the neutrino experiments in the near future. One such example is the nonstandard flavor dependent interaction. In fact it was pointed out that there is some discrepancy between the mass squared difference of the solar neutrino data and that of the KamLAND experiment, and a hypothesis has been put forwarded to explain this difference from this nonstandard interaction. In our work we have discussed in detail how the experiments, such as atmospheric neutrino observation at Hyperkamiokande, the T2HKK experiment and the DUNE experiment can probe the nonstandard interaction.
