Description
An accurate calibration of the energy measurement of electron and photon is needed 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. The
Z->ee sample is also used to measure the energy resolution. The results obtained with the pp collisions data at sqrt(s)=13 TeV in 2016 (2015) corresponding to an integrated luminosity of 33.9 (3.1)fb-1 of sqrt(s)=13 TeV are presented as well as the corresponding uncertainties on the electron and photon energy scales.
