Nuclear effects in charged-current quasielastic neutrino-nucleus scattering

TL;DR

This paper compares two relativistic models for predicting charged-current quasielastic neutrino-nucleus scattering cross sections, analyzing meson-exchange effects and comparing results with MiniBooNE data.

Contribution

It introduces a comparison between the SuSA and a relativistic mean field microscopic model for neutrino-nucleus interactions, including meson-exchange currents.

Findings

Both models provide predictions consistent with experimental data.

Meson-exchange currents significantly affect the two-particle two-hole sector.

Results highlight differences and similarities between the two approaches.

Abstract

After a short review of the recent developments in studies of neutrino-nucleus interactions, the predictions for double-differential and integrated charged current-induced quasielastic cross sections are presented within two different relativistic approaches: one is the so-called SuSA method, based on the superscaling behavior exhibited by electron scattering data; the other is a microscopic model based on relativistic mean field theory, and incorporating final-state interactions. The role played by the meson-exchange currents in the two-particle two-hole sector is explored and the results are compared with the recent MiniBooNE data.
