Abstract
Neutrino oscillation has been observed and shown to be consistent with the idea that the oscillations are due to the co-existence of three mass and three flavor eigen-states. This is confirmed by the dependence on L/E and the observation of the explicit flavor changes associated with the oscillations in νμ → ντ and νμ → νe. The three mixing angles, which corresponds to the mixing of the three neutrino states, have been measured. They are large compared to those of quarks, especially the mixing of second and third generation is almost maximal. Reactor and accelerator data are consistent with three-neutrino framework at 10% level. Next generation long baseline neutrino experiments will clarify the mass hierarchy, relation of νμ, ντ and second, third mass states and may discover CP violation in neutrino oscillation. However, to investigate the structure of flavor physics further, it will be necessary to have critical tests of the three-neutrino framework itself and the origin of possible CP violation in lepton.
