Final Performances for electron and photon calibration, reconstruction and identification with the ATLAS detector

Year: 2024

Type: conference-paper

Abstract: At the LHC, electrons and photons play a crucial role for precision measurements of the Higgs Bosons properties as well as of Standard Model parameters such as the weak mixing angle or the W boson mass. In addition, they are crucial for searches such as Di-Higgs production or Beyond Standard Model processes with multi-lepton final states. These challenging measurements rely on a good understanding of the detector performance in order to keep under control the systematic uncertainties arising from electron and photon detection. After triggering, prompt electron and photon detection goes through the steps: reconstruction, energy calibration, and identification. This work presents the final performances for each of those steps with the ATLAS detector for LHC Run 2.
