| Research Abstract |
In this research, we searched for electron-neutrino events in Super-Kamiokande in the T2K neutrino oscillation experiment with the J-PARC neutrino beam. We observed 6 such events, while the expected number of background events was 1. 5. This is the indication for muon-neutrino to electron neutrino oscillations, suggesting the so-far unknown. 13 is rather large.
