Neutral current (anti)neutrino scattering: relativistic mean field and superscaling predictions

TL;DR

This paper compares two nuclear models, SuSA and RMF, to predict neutral current neutrino and antineutrino scattering cross sections, fitting parameters to experimental data and providing new theoretical predictions.

Contribution

It introduces a comparative analysis of SuSA and RMF models for neutral current scattering, including parameter fitting and antineutrino predictions.

Findings

Good agreement with MiniBooNE data for the ratio $( u p o u p)/( u N o u N)$

Parameter fits suggest specific values for $M_A$ and $g_A^{(s)}$

Predictions extend to antineutrino scattering scenarios.

Abstract

We evaluate the neutral current quasi-elastic neutrino cross section within two nuclear models: the SuSA model, based on the superscaling behavior of electron scattering data, and the RMF model, based on relativistic mean field theory. We also estimate the ratio $(\nu p \to \nu p)/(\nu N \to \nu N)$ and compare with the MiniBooNE experimental data, performing a fit of the parameters $M_A$ and $g_A^{(s)}$ within the two models. Finally, we present our predictions for antineutrino scattering.
