Neutrino nucleus reactions at high energies within the GiBUU model

TL;DR

This paper uses the GiBUU model to analyze neutrino and antineutrino interactions with iron at medium energies, comparing results with experimental data and predicting outcomes for future experiments.

Contribution

It applies the comprehensive GiBUU model to high-energy neutrino-nucleus reactions, including all relevant channels and final state interactions, providing new predictions for pion spectra in Miner$ u$a.

Findings

Final state interactions significantly alter outgoing hadron spectra.

Model results agree with NOMAD and MINOS cross section data.

Predicted pion spectra for Miner$ u$a are provided.

Abstract

The GiBUU model, which implements all reaction channels relevant at medium neutrino energy, is used to investigate the neutrino and antineutrino scattering on iron. Results for integrated cross sections are compared with NOMAD and MINOS data. It is shown, that final state interaction can noticeably change the spectra of the outgoing hadrons. Predictions for the Miner$\nu$a experiment are made for pion spectra, averaged over NuMI neutrino and antineutrino fluxes.
