Energy Reconstruction with Software Compensation Techniques in a highly granular Scintillator - Tungsten Hadronic Calorimeter — •Christian Winter and Frank Simon for the CALICE-D collaboration — Max-Planck-Institut für Physik, Föhringer Ring 6, 80805 München

The CALICE Collaboration is developing highly granular calorimeters for future high-energy physics experiments. One of the technologies is the Analog Hadron Calorimeter (AHCAL), based on plastic scintillator tiles with SiPM readout. In the context of the multi-TeV e⁺e⁻ collider CLIC, the performance of the AHCAL was studied with Tungsten absorbers. We study the hadronic energy resolution of this prototype with local software compensation techniques, which apply energy-density dependent weights on local energy deposits to improve the energy reconstruction, primarily by correcting for the difference in response to electromagnetic and purely hadronic components of the particle showers. Preliminary results of a study perfomed on pion data from 10 GeV to 80 GeV recorded at the CERN SPS will be presented.
