This paper describes the reconstruction of electrons and photons with the ATLAS detector, 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 prompt 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−1 of proton-proton collision data collected at √ s = 13TeV between 2015 and 2017.

- Combined measurements of Higgs boson production and decay using up to $80$ fb$^{-1}$ of proton-proton collision data at $\sqrt{s}=$ 13 TeV collected with the ATLAS experiment (2019, methodology): “The analysis follows the strategy described in the previous publication [11], but employs improved event reconstruction and electron reconstruction [125] techniques, and defines additional event categories to enhance sensitivity to the production of the SM Higgs boson associated with a vector boson ”
- ATLAS data quality operations and performance for 2015-2018 data-taking (2019, unknown): “The ID system provides essential information for the reconstruction of physics objects such as electrons [5], muons [6], τ -leptons [7], photons [5] and jets [8], as well as for identification of jets containing b -hadrons [9], and for event-level quantities that use charged-particle tracks as input.”
