| Outline of Final Research Achievements |
Three parameters which are related to the neutrino oscillation are remained as unknown or unmeasured with enough precision. Especially, mass hierarchy pattern and CP phase in the MNS matrix are one of the main targets for the next generation neutrino experiment.
In this study, we reanalyze the physics potential of Tokai-to-Kamioka-and-Korea (T2KK) and Tokai-to-Kamioka-and-Oki(T2KO) proposal, which are the ideas for the extension of the T2K experiment, with more realistic conditions. From our analysis, the mass hierarchy is determined with 3-5 sigma by the T2KK experiment and 1-4 sigma by the T2KO experiment. We also find that the CP phase can be measured with the uncertainty of 20-50 degree by both experiments. These results are depending on the mass hierarchy and the value of CP phase which are realized in nature.
