  The analysis of the recent charged-current neutrino-nucleus scattering cross
sections measured by the ArgoNeuT Collaboration requires relativistic
theoretical descriptions also accounting for the role of final-state
interactions. In this work, we evaluate differential neutrino-nucleus cross
sections with the relativistic Green's function model, where final-state
interactions are described in the inclusive scattering consistently with the
exclusive scattering using a complex optical potential. The sensitivity to the
parameterization adopted for the phenomenological optical potential is
discussed. The predictions of the relativistic Green's function model are
compared with the results of different descriptions of final-state
interactions.
