Superscaling in electron-nucleus scattering and its link to CC and NC QE neutrino-nucleus scattering

TL;DR

This paper reviews the superscaling approach (SuSA) for neutrino-nucleus scattering, comparing its predictions with experimental data and analyzing the impact of scaling violations like meson exchange currents.

Contribution

It introduces the application of the SuSA model to both CC and NC neutrino-nucleus scattering and examines the effects of scaling violations on predictions.

Findings

SuSA provides reasonable predictions for cross sections.

Scaling violations significantly affect the results.

Meson exchange currents contribute to scaling violations.

Abstract

The superscaling approach (SuSA) to neutrino-nucleus scattering, based on the assumed universality of the scaling function for electromagnetic and weak interactions, is reviewed. The predictions of the SuSA model for bot CC and NC differential and total cross sections are presented and compared with the MiniBooNE data. The role of scaling violations, in particular the contribution of meson exchange currents in the two-particle two-hole sector, is explored.
