Preliminary results from hadron shower data with the CALICE tile AHCAL prototype

This note presents preliminary CALICE results obtained analyzing the data collected during the test-beam running periods in 2006 and 2007 at CERN. The response of the Analog Hadronic Calorimeter (AHCAL) to hadronic showers is investigated and compared to various Monte Carlo models. Studies on the effect of the shower leakage on the reconstructed energy and energy resolution have been performed. First results are presented, which are obtained by applying a na¨ıve particle flow approach to reconstruct clusters in real data. This note summarizes the developments in the analysis of hadronic showers in the AHCAL and TCMT. Three main topics are covered: the study of the hadronic response of the calorimeter and comparison to MC models, shower leakage studies and two-shower separation studies.
