Description

An accurate calibration of the energy measurement of electron and photon is paramount for many ATLAS physics analysis. The calibration of the energy measurement is performed in-situ using a large statistics of Z->ee events. A pre-requisite of this calibration is a good understanding of the material in front of the calorimeter and of the inter-calibration of the different calorimeter layers. Z->ee events are also employed to measure the energy resolution. The results obtained with the pp collisions data recorded in 2015 at sqrt(s)= 13 TeV, corresponding to an integrated luminosity of 3.2 fb-1, as well as the corresponding uncertainties on the electron and photon energy scales, are presented.
