Description
We outline the sensitivity of the Intermediate Water Cherenkov Detector (IWCD) under construction 870m from the source of the Tokai to Kamioka beam to Charged Current (CC) and Neutral Current (NC) NSI via the ratio of NC and CC quasi-elastic (QE) events. The IWCD will leverage measurements of the beam at multiple off-axis angles to reduce systematic uncertainties and precisely measure the scattering cross-section of neutrinos. We find the use of three off-axis measurements can greatly reduce degeneracies and probe flavor conserving isoscalar NC NSI with vector and axial structures below existing limits. We also demonstrate sensitivity to left chiral isoscalar CC NSI, as well as vector and axial flavor changing neutral currents (FCNC). These results validate the efficacy of multiple off-axis measurements as a means to make precise measurements by canceling systematic uncertainties.
