摘要：
T2K is a long-baseline experiment built to measure neutrino oscillations. A muon neutrino (anti-neutrino) beam is produced at the J-PARC accelerator complex and sent towards the near detector located 280 meters away from the neutrino source and the far detector at 295 kilometers. The change in the measured intensity and composition of the beam is used to extract the oscillation parameters. The T2K experiment has provided 2 sigma confidence intervals for delta(CP) phase and improved the precision of the theta(23) and Delta m(32)(2) measurement. A summary of the neutrino oscillation results for 1.49 x 10(21) POT in neutrino-mode and 1.63 x 10(21) POT in anti-neutrinomode (January 2010-May 2018) is presented.
