本文描述了用ATLAS探测器重建电子和光子，用于测量和利用完整的大型强子对撞机RUN 2数据集进行搜索。介绍了一种改进的能量聚类算法，并详细讨论了它对瞬发电子和光子的测量和识别的意义。影响性能的校正和校准，包括能量校准、识别和隔离效率，以及重建电子候选电荷的测量，使用在2015年至2017年期间从S=13TeV根收集的高达81 FB(-1)的质子-质子碰撞数据来确定。
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 root s = 13 TeV between 2015 and 2017.
