| Research Abstract |
The neutrino oscillation parameter,θ_13, which has still been unknown, is measured by the T2K experiment. The J-PARC neutrino beam is observed at Super-Kamiokande after 295km flight. This project takes charge of the analysis of Super-Kamiokande data from whole T2K activities. The 6 electron-like neutrinos are observed in the J-PARC neutrino beam sample. The resultant oscillation parameter is 0. 03<sin^22θ_13<0. 28(90% C. L.). This is the first result to give the finite value ofθ_13.
