Nuclear effects in Neutrino Nuclear Cross-sections

TL;DR

This paper investigates how nuclear effects influence neutrino and antineutrino scattering cross-sections, accounting for nucleon motion and medium modifications, with a focus on quasielastic and pion production processes.

Contribution

It provides a detailed theoretical analysis of nuclear effects in neutrino scattering using local density approximation and $ riangle$ resonance models.

Findings

Nucleon motion significantly affects scattering cross-sections.

Medium modifications alter weak transition strengths and $ riangle$ properties.

Results improve understanding of neutrino-nucleus interactions.

Abstract

Nuclear effects in the quasielastic and inelastic scattering of neutrinos(antineutrinos) from nuclear targets have been studied. The calculations are done in the local density approximation which take into account the effect of nucleon motion as well as renormalisation of weak transition strengths in the nuclear medium. The inelastic reaction leading to production of pions is calculated in a $\Delta$ dominance model taking into account the renormalization of $\Delta$ properties in the nuclear medium.
