Contribution

It introduces a unified relativistic framework for electron and neutrino scattering, comparing FSI models and analyzing their effects on cross sections and scaling.

Findings

Relativistic Green's function and mean field approaches yield similar flux-conserving results.

Differential cross sections vary with energy and FSI model.

Scaling properties are consistent across models.

Abstract

Relativistic models developed for the exclusive and inclusive quasielastic (QE) electron scattering have been extended to charged-current (CC) and neutral-current (NC) neutrino-nucleus scattering. Different descriptions of final-state interactions (FSI) are compared. For the inclusive electron scattering the relativistic Green's function approach is compared with calculations based on the use of relativistic purely real mean field potentials in the final state. Both approaches lead to a redistribution of the strength but conserving the total flux. Results for the differential cross section at different energies are presented. Scaling properties are also analyzed and discussed
