英文摘要
We aim for improving the T2K sensitivity of electron neutrino appearance and proceeding towards future experiment for CP violation measurement. For these purpose, we performed a precise measurement of production cross section of the neutrino parent particles. Based on studies in this project, we reported the indication of electron neutrino appearance in 2011, and furthermore we reported the evidence with 3.2σsignificance in 2012. We also developed a new-type water Cherenkov detector in order to improve near-to-far extrapolation in T2k experiment. We have reported results of this project at international conferences, Physical Society of Japan meetings and journalarticles.
