Electron versus Muon Neutrino Induced Cross Sections in Charged Current Quasielastic Processes

Differences between νₑ and ν_μ 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 ⁴⁰Ar and ¹²C targets. We demonstrate that a proper treatment of the final nucleon's wave function confirms the dominance of ν_μ over νₑ induced cross sections at forward lepton scattering.
