New Model Comparison for Semi-inclusive Charged-current Electron and Muon Neutrino Scattering by Ar40 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 40Ar 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.
