The reconstruction of the energy lost by a 120 GeV muon in the highly granular hadron calorimeter for the International Linear Collider

The Calice collaboration developed a new design of a hadron calorimeter, featured by both a high longitudinal granularity and a fine transverse segmentation. This property allows identifying and reconstructing the interaction of single particles with the detector with an unprecedented spatial resolution. The main topic of this note is the quantification of the systematic introduced by the operation of the detector at the energy scale of a minimum ionizing particle. The muon signal is the natural candidate for the observation of an improper behaviour of the detector, because it is the smallest physical signal with well defined and predicted peak and width. Besides, the reconstruction of the total energy lost by 120 GeV muons in the detector is shown, comparing the Monte Carlo expectation with the data collected during the test beam of a prototype of the hadron calorimeter.
