Research Abstract

To understand the neutrino mixing phenomena and to study theorigin of neutrino mass, the neutrino scattering experiment (Fermilab E954 SciBooNE)and the long baseline neutrino oscillation experiment (J-PARC E11 T2K) were conductedby using the accelerator neutrino beams. In SciBooNE, we measure the neutrino crosssections with the world best precision. In T2K, we discover the new oscillation channelfrom a muon neutrino to an electron neutrino. In consequence, we greatly advance theknowledge of neutrinos.
