Studies on the Electron Reconstruction Efficiency for the Beam Calorimeter of an ILC Detector

Understand

In this talk recent simulation results on the single high energy electron reconstruction with the Beam Calorimeter for the ILD detector are presented.

• Guinea Pig is used to generate the e+e- pair background and GEANT4 for the simulation of electron showers in the calorimeter.
• An algorithm was developed for the sHEe reconstruction on top of the large e+e- background.
• The efficiency of the sHEe reconstruction is estimated for the nominal and SB-2009 ILC beam parameters.
