Geant4 Simulation and Comparison with Reconstructed Muon Events at the H8 Testbeam

This document presents the first comparison of experimental data taken at H8 with the Geant4 simulation. The work investigates the secondary particles production by muons and their possible impact on track segment reconstruction in comparison with Geant4 predictions. The basic elements of the analysis are the reconstructed track segments on each of the three MDT stations of the testbeam setup. The purpose of the work is twofold: to provide simulation of the data collected for track reconstruction and alignment studies and to perform validation of the Geant4 physics content. Here the reliability of the developed simulation code is validated through the agreement found with data which can be estimated at the level of 1% absolute.
