[Show abstract][Hide abstract] ABSTRACT: The precise measurement of hadronic jet energy is crucial to maximise the
physics reach of a future Linear Collider. An important ingredient required to
achieve this is the efficient identification of photons within hadronic
showers. One configuration of the ILD detector concept employs a highly
granular silicon-tungsten sampling calorimeter to identify and measure photons,
and the GARLIC algorithm described in this paper has been developed to identify
photons in such a calorimeter. We describe the algorithm and characterise its
performance using events fully simulated in a model of the ILD detector.

[Show abstract][Hide abstract] ABSTRACT: In order to profit from the high granularity of the calorimeters proposed for the ILC that are suitable for the Particle Flow Approach, specialised clustering algorithms have to be developped. GARLIC is such an algorithm with the goal to find and identify pointing photons in the electromagnetic calorimeter. This would help to improve the energy resolution on the photon contribution in jets.
