Description
In 2014 the T2K experiment will reverse the polarity of the magnetic horns
and begin running with an anti-neutrino beam for the first time. Differences
in the oscillation probabilities between neutrinos and anti-neutrinos may provide
insight into charge-parity violation in the leptonic sector. In order to
measure the the anti-electron neutrino contamination in T2K's anti-muon neutrino
beam, an anti-neutrino selection has been developed for the ND280 near detector
and tested using Monte-Carlo simulations of an anti-neutrino beam. The electron anti-neutrino
selection faces new challenges not seen in the electron neutrino selection. The most significant
challenge is the removal of protons which were removed by the charge requirement in the electron
neutrino selection but are a significant background in the electron anti-neutrino analysis.
