【 摘 要 】

The T2K long baseline neutrino oscillation experiment in Japan uses a muon neutrino (antineutrino) beam produced by J-PARC and propagating through 295 km to the Super-Kamiokande water Cherenkov detector. The most recent oscillation results from T2K for neutrinos and antineutrinos are reported here. Both disappearance and appearance data are analyzed, providing leading results for sin2θ23and . When fitting using a prior on sin22θ13from reactor measurements, T2K is able to put the first constraints on the CP-violating phase δCP, disfavouring the CP-conserving values 0 and π at 90% C.L. Prospects for the future of T2K are also discussed.
