Description

The T2K experiment is a long-baseline neutrino experiment designed to measure $\nu_{\mu } \longrightarrow \nu_{\mu}$ and $\nu_{\mu } \longrightarrow \nu_{e}$ oscillation. With the recent firm establishment of $\nu_{e}$ appearance by T2K, future precision $\nu_{e}$ appearance measurements can be used to explore CP violation in neutrino interactions. However such an exploration requires detailed understanding of the $\nu_{e}$ ($\bar{\nu}_{e}$) interactions, as well as contamination of $\nu_{e}$ ($\bar{\nu}_{e}$) in the $\nu_{\mu}$ ($\bar{\nu}_{\mu}$) beam. To this end, the T2K off-axis $\pi^{0}$ detector (P0D) has been used to measure $\nu_{e}$ charged current interaction rates on water. We present the details of the analysis, including the selection criteria and the systematic uncertainties. Finally, we will discuss prospects for the charged current $\bar{\nu}_{e}$ interaction rate measurement with the P0D.
