  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.
