Abstract
The T2K (Tokai to Kamioka) experiment is a long-baseline neutrino experiment designed to measure numu disappearance and nue appearance from the numu beam. The T2K experimental setup consists of J-PARC (Japan Proton Accelerator Research Complex) accelerator, a near detector (ND280) and a far detector (Super-Kamiokande). With the recent firm establishment of nue appearance by T2K, future precision nue appearance measurements can be used to explore CP-violation in neutrino interactions. However such an exploration requires detailed understanding of the nue interactions, as well as contamination of nue in the numu beam. The presence of the nue component in the beam accounts for 1.2% of the beam, which is the main background in the nue appearance measurement. Moreover, as Super-Kamiokande is a large water Cherenkov detector, neutrino interaction measurements on water are important to constrain the neutrino cross-section systematic uncertainty. To this end, the T2K off-axis π0 detector (PØD) has been used to measure νe charged current interaction rates on water. The details of the analysis including the selection criteria and the systematic uncertainties are presented in this thesis. In addition, prospects for the charged current anti-nue interaction rate measurement with the PØD will be discussed. These are pioneering measurements of the nue interaction rate, particularly on water, which will become crucial in future CP-violation searches. | The T2K (Tokai to Kamioka) experiment is a long-baseline neutrino experiment designed to measure numu disappearance and nue appearance from the numu beam.
