Abstract

The T2K experiment is a long baseline neutrino oscillation experiment located in Japan, using a neutrino beam generated at J-PARC accelerator complex. The beam may be produced in νμ or ¯νμ mode. The oscillations are studied by measuring neutrino interactions in near detector complex 280 meters from the beam source and in far detector Super-Kamiokande 295 km away. Particularly interesting aspect of the oscillation analysis is probing the CP violation phase δCP by comparing (νμ → νe) and (¯νμ → ν¯e) appearance probabilities. We present results of the joint oscillation analysis for neutrino and anti-neutrino samples based on total collected statistics of 3.13×1021 POT. CP conservation is excluded at 2 σ level and Normal Hierarchy is preferred with posterior probability of 89%.
