【摘要】T2K is a long-baseline neutrino experiment, aiming at precise measurements of neutrino oscillation parameters, including the mixing angle 23 and CP violation phase. T2K uses a beam produced in J-PARC in Japan that can provide both muon neutrinos and anti-neutrinos. An off-axis near detector complex has been built at a distance of 280 m from the proton target in order to measure the un-oscillated neutrino/anti-neutrino spectra. Then those spectra are compared to the oscillated measurements in the Super-Kamiokande detector, which is a 50 kton water detector at a distance of 295 km from the beam. This comparison gives the oscillation parameter information. In this talk, the oscillation results with data runs from 2010 to 2017, which consists of 14.7 x 10E20 accumulated POT in neutrino mode and 7.6 x 10E20  POT in anti-neutrino mode will be presented. It is the first time that T2K announced CP-conservation excluded at 90% C.L.
