报告使用 Z、W 和 J/psi 粒子的衰变对 LHC 上的 ATLAS 探测器的电子性能进行了详细测量。使用 2010 年在根 s = 7 TeV 处收集的数据，对应于近 40 pb(-1) 的积分光度。讨论了内部探测器和电磁量热器的相互对准、电子能量尺度和分辨率的确定以及响应均匀性和线性度方面的性能。还给出了电子识别、重构和触发效率，以及电荷错误识别概率。
Detailed measurements of the electron performance of the ATLAS detector at the LHC are reported, using decays of the Z, W and J/psi particles. Data collected in 2010 at root s = 7 TeV are used, corresponding to an integrated luminosity of almost 40 pb(-1). The inter-alignment of the inner detector and the electromagnetic calorimeter, the determination of the electron energy scale and resolution, and the performance in terms of response uniformity and linearity are discussed. The electron identification, reconstruction and trigger efficiencies, as well as the charge misidentification probability, are also presented.
