Application of software compensation to 2011 W-AHCAL test beam data

The note presents a study of the application of a software compensation technique to pion showers detected in the CALICE highly granular scintillator-tungsten analogue hadron calorimeter during a test beam campaign in 2011. The software compensation technique was developed for the calorimeter with steel absorber and the same scintillator-SiPM active elements as in the prototype under study. The improvement of resolution due to software compensation in the calorimeter with tungsten absorber is 2–7%, which is smaller than the 10–25% improvement reported previously for the steel absorber calorimeter in the same energy range from 10 to 80 GeV. This reduced improvement by software compensation is expected, since the prototype with tungsten absorber is close to be compensating at hardware level.
