New model comparison for semi-inclusive charged-current electron and muon neutrino scattering by ${}^{40}$Ar in the energy range of the MicroBooNE experiment

Abstract

In this work we present a comparison of semi-inclusive muon and electron neutrino cross sections with ${}^{40}$Ar target measured by the MicroBooNE Collaboration with the predictions of an unfactorized model based on the relativistic distorted wave impulse approximation (RDWIA) and the SuSAv2-MEC model implemented in the neutrino event generator GENIE. The predictions based on the RDWIA approach, with a realistic description of the initial state and a phenomenological relativistic complex optical potential for the description of final state interactions, better describe the measured cross sections than GENIE-SuSAv2 and RDWIA with a purely real potential.
