Abstract

The Compact Muon Solenoid (CMS) experiment implements a sophisticated two-level triggering system composed of a custom-designed hardware Level-1 trigger and a software High-Level-Trigger. A new Level-1 trigger architecture with improved performance is now being used to maintain thresholds compatible with the CMS physics program despite the challenging luminosity conditions experienced during Run II. We present the performance of the upgraded CMS electron and photon trigger. The calorimeter trigger system plays a central role in achieving the ambitious physics program of Run II. The upgraded trigger uses the granularity of the calorimeters to optimally reconstruct the electromagnetic trigger objects. The performance of the new trigger system will be presented, based on proton-proton collision data collected in Run II. The selection techniques used to trigger efficiently will be presented, along with the strategies employed to guarantee efficient triggering for new resonances and other new physics signals involving electron/photon final states.
