|Outline of Final Research Achievements
We conducted research on neutrino oscillation, measurements by using an anti-neutrino beam, and development of high performance photon-sensor for a next generation large-scale neutrino experiment. In the T2K experiment, we observed the signal from the muon neutrino to the electron neutrino and found the appearance of the electron neutrino with significance of 7.3 σ. We measured the oscillation probability to the electron neutrino and constrained the neutrino CP violation parameter for the first time in the world (δCP = - 0.5 π was the best). An anti-neutrino beam was generated, and the parameters of anti-neutrino oscillation were measured with the highest precision.
We studied the sensitivity of neutrino CP violation with the next-generation experiment, Hyper Kamiokande. We also succeeded in developing a high performance photon-sensor (joint work with Hamamatsu Photonics).
