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/$Psi$$ ightarrow$ee, W$ ightarrow$e$ u$ and QCD background samples for calibration, efficiency and fake rate measurements. In the 20...

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/$Psi$$ ightarrow$ee, W$ ightarrow$e$ u$ and QCD background samples for calibration, efficiency and fake rate measurements. In the 2011 p-p 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 poster summarizes the evolution and performance of ATLAS electron and photon triggers used in 2011 p-p collision data-taking.
