Abstract
T2K reports its first results in the search for violation in neutrino oscillations using appearance and disappearance channels for neutrino- and antineutrino-mode beams. The data include all runs from January 2010 to May 2016 and comprise protons on target in neutrino mode, which yielded in the far detector 32 -like and -like events, and protons on target in antineutrino mode, which yielded 4 -like and -like events. Reactor measurements of have been used as an additional constraint. The one-dimensional confidence interval at 90% for the phase spans the range (, ) for normal mass ordering. The conservation hypothesis (, ) is excluded at 90% C.L.
