Electron and photon performance measurements with the ATLAS detector using the 2015-2017 LHC proton-proton collision data
Abstract
This paper describes the reconstruction of electrons and photons with the ATLAS detector, as employed for measurements and searches exploiting the complete LHC Run 2 dataset. An improved energy clustering algorithm is introduced, and its implications for the measurement and identification of electrons and photons are discussed in detail. Corrections and calibrations that affect performance, including energy calibration, identification and isolation efficiencies, and the measurement of the charge of reconstructed electron candidates are determined using up to 81 fb of proton-proton collision data collected at 13 TeV between 2015 and 2017.
