Data were collected with electron and hadron beams in the energy range 8 to 80 GeV.  The analysis described here focuses on the interactions of pions in the calorimeter.  One of the main objectives of the CALICE program is to validate the Monte Carlo tools available for the design of a full-sized detector.  The interactions of pions in the Si-W calorimeter are therefore confronted with the predictions of various physical models implemented in the GEANT4 simulation framewo","authors_text":"A.
