Nucleon Emision Off Nuclei Induced By Neutrino Interactions

TL;DR

This paper reviews nuclear effects influencing neutrino-nucleus cross sections, comparing models for quasi-elastic reactions at around 1 GeV, with focus on medium corrections and nucleon rescattering.

Contribution

It provides a comparative analysis of existing models describing nuclear effects in neutrino interactions at ~1 GeV energy.

Findings

Different models vary in their treatment of medium corrections.

Rescattering of ejected nucleons significantly impacts cross section predictions.

Recent MiniBoone data helps constrain theoretical models.

Abstract

We make a review of the main nuclear effects that affect neutrino-nucleus cross sections. We discuss how the different models in the literature try to describe these different effects, and thus try to compare between them. We focus on the quasi-elastic reaction in the neutrino energy region of around 1 GeV, where recent data from MiniBoone are available. Among the issues discussed are the different treatment of medium corrections to initial and nal state nucleon wave functions and the problem of the rescattering of ejected nucleons.
