Abstract
A detailed study of hadronic interactions is presented using data recorded with the highly granular CALICE silicon-tungsten electromagnetic calorimeter. Approximately 350,000 selected pi(-) events at energies between 2 and 10 GeV have been studied.
The predictions of several physics models available within the GEANT4 simulation tool kit are compared to this data. A reasonable overall description of the data is observed; the Monte Carlo predictions are within 20% of the data, and for many observables much closer.
The largest quantitative discrepancies are found in the longitudinal and transverse distributions of reconstructed energy. (C) 2015 Published by Elsevier B.V.
