Relativistic descriptions of quasielastic charged-current neutrino-nucleus scattering: application to scaling and superscaling ideas

TL;DR

This paper compares relativistic models for neutrino-nucleus quasielastic scattering, analyzing their scaling properties and implications for interpreting experimental data from MiniBooNE.

Contribution

It introduces a comparative analysis of relativistic mean field and Green function approaches for neutrino scattering, focusing on scaling behaviors.

Findings

Both models produce similar inclusive cross sections.

Scaling and superscaling properties are confirmed in both approaches.

Results support the use of relativistic models for neutrino interaction analysis.

Abstract

The analysis of the recent experimental data on charged-current neutrino-nucleus scattering cross sections measured at MiniBooNE requires fully relativistic theoretical descriptions also accounting for the role of final state interactions. In this work we evaluate inclusive quasielastic differential neutrino cross sections within the framework of the relativistic impulse approximation. Results based on the relativistic mean field potential are compared with the ones corresponding to the relativistic Green function approach. An analysis of scaling and superscaling properties provided by both models is also presented.
