Performance of the ATLAS Electron and Photon Trigger in p-p Collisions at sqrt{s} = 7 TeV in 2011

Electron and photon triggers are used for signal selection in a wide variety of ATLAS physics analyses. Further dedicated triggers are provided for the collection of J/ψ →e+ e− , W→ eν and QCD background samples for calibration, efficiency and fake rate measurements. In the 2011 proton-proton data-t...

description Electron and photon triggers are used for signal selection in a wide variety of ATLAS physics analyses. Further dedicated triggers are provided for the collection of J/ψ →e+ e− , W→ eν and QCD background samples for calibration, efficiency and fake rate measurements. In the 2011 proton-proton data-taking period, the increasing luminosity and pile-up conditions at the LHC demanded the use of progressively higher energy thresholds and tighter selections to control the trigger rates. This note summarizes the evolution and performance of ATLAS electron and photon triggers used in 2011 data-taking.
