Lepton production cross sections in quasielastic $\nu/\bar{\nu}-$A scattering

TL;DR

This paper calculates (anti)neutrino-induced charged-current quasielastic cross sections on various nuclear targets at energies up to 1 GeV, considering lepton mass effects, nuclear medium effects, and form factor uncertainties to aid neutrino oscillation experiments.

Contribution

It provides detailed cross section calculations including nuclear medium effects and lepton mass considerations, which are crucial for interpreting neutrino oscillation data.

Findings

Lepton mass effects significantly influence cross sections.

Nuclear medium effects alter the cross section values.

Uncertainties in form factors impact the precision of predictions.

Abstract

We present the results of (anti)neutrino induced CCQE cross sections from some nuclear targets in the energy region of $E_\nu \le 1 GeV$. The aim of the study is to confront electron and muon production cross sections relevant for $\nu_\mu \leftrightarrow \nu_e$ or $\bar\nu_\mu \leftrightarrow \bar\nu_e$ oscillation experiments. The effects due to lepton mass and its kinematic implications, second class currents and uncertainties in the axial and pseudoscalar form factors are discussed for (anti)neutrino induced reaction cross sections on free nucleon as well as the nucleons bound in a nucleus where nuclear medium effects influence the cross section. The calculations have been performed using local Fermi gas model with nucleon correlation effects. The details are given in Ref.[1].
