Study of e/gamma trigger for the electron calibration stream
Abstract
This note describes a study of the possibilities for selecting an electron calibration stream using the High level electron trigger (Level 2 and the event filter). Using the electromagnetic calorimeter reconstruction and the track reconstruction algorithms, an evaluation has been performed of the selection efficiencies and purities for different physics channels with single or double electrons in the final state. A study of the calibration stream composition, including the background from QCD processes, is presented.
