Electron versus muon neutrino induced cross sections in charged current quasi-elastic processes

Nuclear Theory 2019-08-07 v2

Abstract

Differences between νe\nu_e and νμ\nu_{\mu} quasielastic cross sections are essential in neutrino oscillation analyses and CP violation searches for experiments such as DUNE and T2HK. The ratio of these is however poorly known experimentally and for certain kinematic regions theoretical models give contradictory answers. We use two independent mean-field based models to investigate this ratio using 40^{40}Ar and 12^{12}C targets. We demonstrate that a proper treatment of the final nucleon's wave function confirms the dominance of νμ\nu_{\mu} over νe\nu_e induced cross sections at forward lepton scattering.
