Fig. 11.9 Mean longitudinal shower profile, starting at the layer of the first interaction, for pion
beams in CALICE iron-scintillator analog hadronic calorimeter. Pion energies are 8 GeV (left),
18 GeV (center) Top row: data (circles) compared with FTFP_BERT physics list of GEANT4
version 9.4. The parts deposited by different particles (electrons/positrons, pions and protons) in
the simulation are shown. Lower 3 rows: ratios between selected physics lists and data. (We note
that the CHIPS and LHEP physics lists were withdrawn in Geant4 release 10.0). Reproduced from
