TL;DR

This paper extends relativistic models from electron scattering to neutrino-nucleus interactions, comparing different FSI descriptions and analyzing scaling properties to improve understanding of quasielastic scattering processes.

Contribution

It introduces an extension of relativistic quasielastic models to neutrino scattering and compares various FSI approaches, including the relativistic Green's function method.

Findings

Both FSI approaches redistribute strength while conserving flux.

Differential cross sections are calculated at various energies.

Scaling properties are analyzed and discussed.

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.
