摘要

ATLAS的电子和光子触发器覆盖了从5 GeV到几TeV的横向能量，对于记录各种物理学的信号至关重要:从标准模型过程到寻找新现象。为了应对不断增加的亮度和更具挑战性的堆积条件，在质量中心能量为13 TeV的情况下，需要优化触发器选择以控制速率并保持高效率。介绍了Run-2中的ATLAS电子和光子触发器，包括开发的新技术，即使在高堆积条件下也能保持其高性能，以及2018年数据采集的首次效率测量。

ATLAS Electron and Photon Trigger

ATLAS electron and photon triggers covering transverse energies from 5 GeV to several TeV are essential to record signals for a wide variety of physics: from the Standard Model processes to searches for new phenomena. To cope with ever-increasing luminosity and more challenging pile-up conditions at a centre-of-mass energy of 13 TeV, the trigger selections need to be optimized to control the rates and keep efficiencies high. The ATLAS electron and photon trigger in Run-2 is presented, including new techniques developed to maintain their high performance even in high pile-up conditions as well as the first efficiency measurements from the 2018 data taking.
