Abstract:

The T2K collaboration reports two new results using a data set　consisting of 6.57 \times 10^{20} protons on target. Muon neutrino　disappearance analyses produce world-leading precision in the　measurement of the neutrino mixing parameter　\theta_{23}. Moreover,　electron neutrino appearance analyses constrain a CP violating phase　\delta_{CP} by combining our results with the \theta_{13} values　measured by reactor experiments. Our paper on the electron neutrino　appearance analyses (PRL 112, 061802 (2014)) was selected for a“Viewpoint in Physics” of APS,　http://physics.aps.org/articles/v7/15 .In addition to the above results, study on future sensitivities of T2K　will be presented.
