Studies towards optimisation of a highly granular calorimeter for future linear collider detectors — •Huong Lan Tran for the CALICE-D collaboration — Deutsches Elektronen Synchrotron DESY

The Particle Flow approach to calorimetry requires highly granular calorimeters and sophisticated software in order to reconstruct and identify individual particles in complex event topologies. The high calorimeter granularity can also provide a discrimination of the electromagnetic sub-showers in hadron showers. This discrimination can be utilised in an offline weighting scheme, the so-called software compensation technique, to reduce the fluctuation of the calorimeter response due to the electromagnetic sub-showers and therefore improves the energy resolution for single particles. The improvement in the single particle energy resolution can then lead to a better jet energy resolution. This talk will give a detailed description of the software compensation technique and its implementation in Particle Flow reconstruction. The impact of software compensation on the choice of optimal transverse granularity for the Analogue Hadronic Calorimeter (AHCAL) option of the International Large Detector (ILD) concept is also discussed.
