Sensitivity of accelerator-based neutrino experiments to neutrino-electron scattering radiative corrections

Abstract

Future long-baseline experiments will measure neutrino oscillation properties with unprecedented precision that will search for clear signatures of CP violation in the leptonic sector. Near detectors can measure the neutrinoelectron scattering with high statistics, giving the chance for its precise measurement. We study in this work the expectations for the measurement of radiative corrections in this process. We focus on the determination of contributions that are exclusive to the neutrino channels, particularly on the neutrino charge radius. We illustrate how the perspectives in a first clear measurement of this effective quantity are encouraging.
