Abstract

T2K reports its first results in the search for CP violation in neutrino oscillations using appearance and disappearance channels for neutrino- and antineutrino-mode beam. The data include all runs from Jan 2010 to May 2016 and comprise 7.482 × 10²⁰ protons on target in neutrino mode, which yielded in the far detector 32 e-like and 135 µ-like events, and 7.471 × 10²⁰ protons on target in antineutrino mode which yielded 4 e-like and 66 µ-like events. Reactor measurements of sin² 2θ13 have been used as an additional constraint. The one-dimensional confidence interval at 90% for δCP spans the range (−3.13, −0.39) for normal mass ordering. The CP conservation hypothesis (δCP = 0, π) is excluded at 90% C.L.
