Why T2K should run in dominant neutrino mode to discover CP violation ?
arXiv:1702.07885
Abstract
The first hint of the leptonic CP phase $δ_{CP}=-90^\circ$ has already came from the long-baseline neutrino oscillation experiment T2K. This hint is derived from the neutrino data of T2K and currently it is running in the antineutrino mode. In this work we ask the question what should be the proportion of neutrino and antineutrino running of the T2K experiment to discover CP violation in the leptonic sector.
