Abstract: (APS)
Differences between νe and νμ 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 Ar40 and C12 targets. We demonstrate that a proper treatment of the final nucleon’s wave function confirms the dominance of νμ over νe induced cross sections at forward lepton scattering.
