Relativistic Models for Quasi-Elastic Neutrino-Nucleus Scattering

TL;DR

This paper compares two relativistic models for neutrino-nucleus quasielastic scattering, one phenomenological and one microscopic, analyzing their predictions against experimental MiniBooNE data.

Contribution

It introduces and compares two relativistic models for neutrino scattering, incorporating meson exchange currents and validating against experimental data.

Findings

Both models successfully describe differential cross sections.

Microscopic model provides detailed nuclear dynamics insights.

Models show good agreement with MiniBooNE data.

Abstract

Two relativistic approaches to charged-current quasielastic neutrino-nucleus scattering are illustrated and compared: one is phenomenological and based on the superscaling behavior of electron scattering data and the other relies on the microscopic description of nuclear dynamics in relativistic mean field theory. The role of meson exchange currents in the two-particle two-hole sector is explored. The predictions of the models for differential and total cross sections are presented and compared with the MiniBooNE data.
