| Outline of Final Research Achievements |
This project was aiming to solve so called LSND problem which is the unexplained electron neutrino appearance signal in larger mass different square region. The result we obtained was presented at INFN Gran Sasso Laboratory on April 2017.
As a result of analysis for 7000 neutrino interaction observed in the OPERA experiment, we observed 32 electron neutrino candidate events in total. Thanks to this enlarged statistics, we could perform shape analysis rather than counting method. In the 3+1 neutrino oscillation framework, we obtained effective mixing angle on muon and electron neutrino sin^2(2theta_mue) less than 0.019 at large mass difference square.
