Calibration of electrons and photons with the ATLAS detector, and its impact on ATLAS precision measurements
Résumé
Since the discovery of the Higgs boson a lot of effort has been devoted to the measurement of its properties. One of its key parameter is its mass, which has been measured by the ATLAS detector at the LHC. For this measurement a precision calibration of the ATLAS electromagnetic calorimeter is required. The details of this calibration as well as the current understanding of the detector will be described. The measurement of mH and the impact of the calibration will be described.
