Abstract
T2K is a long baseline neutrino oscillation experiment studying the oscillation of Vμ to Ve over the 295 km baseline between the J-PARC accelerator and the Super-Kamiokande water Cherenkov detector.
A 3-flavour, 5 sample v/v joint analysis on the Run 1-9 dataset is performed to measure the neutrino CP phase, ꝺ, where values other than zero and nπ imply a difference in the oscillation of neutrinos and antineutrinos. The 2σ confidence level allowed interval when applying the constraint on sin2(Ɵ13) from reactors in normal mass ordering is [-2:966;-0:628] and for inverted mass ordering is [-1:799;-0:979]. Thus, CP conservation is rejected at 2σ, a world leading measurement.
Differences in event rates are expected for different true values of the neutrino mass ordering and thus T2K has some sensitivity to the neutrino mass ordering. A 3-flavour, 5 sample v/v joint analysis on the Run 1-9 dataset is performed to measure the neutrino mass ordering. No strong evidence against either mass ordering hypothesis is observed.
