Electromagnetic Shower Reconstruction for the Silicon Detector

This report presents a two-pass reconstruction algorithm for electromagnetic showers, based on studies with simulated photons in the highly segmented Silicon Tungsten calorimeter of the Silicon Detector concept for the International Linear Collider. It is shown that the initial reconstruction and identification of the dense shower cores allows shower separation down to 3 cm distance between two photons on the calorimeter surface. First results are shown for the subsequent collection of unassociated hits around the shower cores necessary to reconstruct complete energy deposits by individual particles
