Description

T2K is a neutrino experiment in Japan that measures neutrino and antineutrino
oscillations using a baseline of 295 km, from the near detector "ND280" at
J-PARC, to the far detector "Super-Kamiokande" (SuperK) in Kamioka. ND280
measures the properties of the neutrino beam prior to oscillations, while
SuperK measures the beam after oscillations. In this talk, the most recent
results of neutrino oscillations will be presented, featuring world-leading
sensitivities on the search of Charge-Parity violation, by comparing
oscillation measurements of neutrinos and antineutrinos. Measurements of the
atmospheric oscillation parameters were also extracted, by observing the
disappearance of muon neutrinos and the appearance of electron neutrinos.
Combinations with other experiments such as SuperK and NOvA are also presented.
