Production of charged pions off nuclei with 3...30 GeV incident protons and pions

TL;DR

This paper compares theoretical calculations of charged pion production off nuclei with experimental data from HARP and NA61/SHINE, covering beam energies from 3 to 30 GeV, to validate and extend the model predictions.

Contribution

It introduces a coupled channel transport model (GiBUU) for predicting pion production and compares its results with recent experimental data across a wide energy range.

Findings

Model agrees well with HARP data at 3-13 GeV

Predictions for 30 GeV data align with NA61/SHINE results

Provides validated predictions for pion and kaon production at higher energies

Abstract

We compare calculations for the production of charged pions by pion or proton beams off nuclei calculated within our coupled channel transport model (GiBUU) with recent data of the HARP collaboration for beam energies from 3 up to 13 GeV. Predictions for the 30 GeV data for pions and kaons from the NA61/SHINE experiment are included.
