Analysis of shower shapes of pions and protons from the tungsten analogue hadronic calorimeter

In this report, analysis results of test-beam data taken with the CALICE tungsten analogue hadronic calorimeter prototype are presented. Proton and pion-induced showers originating from a particle beam of an momentum range of 25-150 GeV are examined. As a first part of the study, a comparison between data and two GEANT4 Monte-Carlo simulations with regard to variables describing hadronic shower fluctuations is performed. In the second part of this report, the separation potential of the W-AHCAL for protons and pions is discussed.
