Cross-sections for $\nu_{\mu}$ and $\bar{\nu_{\mu}}$ induced single pion production processes in the few GeV using NuWro

TL;DR

This paper investigates charged-current single pion production cross-sections induced by muon neutrinos and antineutrinos on hydrocarbon targets using the NuWro generator, comparing results with Miner$ u$A experimental data to improve neutrino oscillation background understanding.

Contribution

It provides detailed cross-section calculations for pion production processes using NuWro and compares them with experimental data, enhancing the modeling of neutrino interaction backgrounds.

Findings

Cross-sections calculated with NuWro agree with Miner$ u$A data within uncertainties.

Identifies the role of final state interactions in pion production.

Provides data useful for reducing systematic uncertainties in neutrino oscillation experiments.

Abstract

For a continued progress in the pursuit of neutrino oscillation parameters, we require to have a precise knowledge of the pion production processes which act as a source of backgrounds and systematic uncertainties in neutrino oscillation experiments because pions can mimic a final state electron (positron). Therefore a pion production principal interaction may appear to be quasi-elastic if the pion is absorbed in the final state interactions. Charged-current single pion production processes induced by $\nu_{\mu}$ and $\bar{\nu_{\mu}}$ interactions with hydrocarbon target $(CH_{2})$ has been studied using NuWro event generator and the cross-sections so obtained have been compared with the results of Miner$\nu$A experiment.
