Etalonnage du calorimètre électromagnétique du détecteur ATLAS. Reconstruction des événements avec des photons non pointants dans le cadre d'un modèle supersymétrique GMSB

Abstract : The analysis of testbeam data is focused on the calibration of the ATLAS electromagnetic calorimeter. An electrical model has been developed to predict the shape of the physics pulse out of the calibration one's in order to produce optimal filtering coefficients. They are used to compute energy while minimizing electronic noise and getting rid of any possible time shift. Using these coefficients, the uniformity response is 0.6%, in agreement with the 0.7% global constant term required for the whole calorimeter. The study of non pointing photon is driven by the detection of long lived neutralinos predicted by GMSB SUSY models. A systematic study with a detailed simulation of the ATLAS detector was performed to determine the electromagnetic calorimeter angular resolution for such photons. Results were used to parametrized the detector response and to reconstruct SUSY events from this model.
