TL;DR

This study analyzes how positive hadron showers develop in a high-granularity calorimeter, comparing experimental data from CERN and FNAL with Geant4 simulations to improve understanding of hadronic interactions.

Contribution

It provides detailed measurements of proton and pion showers in a highly granular calorimeter and compares these with Geant4 simulations, enhancing modeling accuracy.

Findings

01

Calorimeter response varies with particle type and energy.

02

Simulation results show good agreement with experimental data.

03

Spatial shower characteristics are characterized across energies.

Abstract

Showers produced by positive hadrons in the highly granular CALICE scintillator-steel analogue hadron calorimeter were studied. The experimental data were collected at CERN and FNAL for single particles with initial momenta from 10 to 80 GeV/c. The calorimeter response and resolution and spatial characteristics of shower development for proton- and pion-induced showers for test beam data and simulations using Geant4 version 9.6 are compared.
