Neutrino Interaction Calculations from MeV to GeV Region

TL;DR

This paper extends a nuclear electron model to neutrino interactions, incorporating nuclear correlations, FSI, and Coulomb effects, providing insights into neutrino-induced reactions and muon capture across various nuclei.

Contribution

It introduces an extended model for neutrino interactions that includes RPA correlations, FSI, and Coulomb corrections, and applies Monte Carlo methods for nucleon rescattering analysis.

Findings

RPA correlations are crucial for neutrino energies 100-500 MeV.

The model successfully describes inclusive muon capture across nuclei.

Monte Carlo simulations elucidate nucleon rescattering effects.

Abstract

The Quasi-Elastic (QE) contribution of the nuclear inclusive electron model developed in Nucl. Phys. A627 543 (1997) is extended to the study of neutrino/antineutrino Charged Current (CC) and Neutral Current (NC) induced nuclear reactions at intermediate energies. Long range nuclear (RPA) correlations, Final State Interaction (FSI) and Coulomb corrections are included within the model. RPA correlations are shown to play a crucial role in the whole range (100--500 MeV) of studied neutrino energies. Results for inclusive muon capture for different nuclei through the Periodic Table are also discussed. In addition, and by means of a Monte Carlo cascade method to account for the rescattering of the outgoing nucleon, we also study the CC and NC inclusive one nucleon knockout reactions off nuclei.
