Electron Reconstruction and Identification at √s = 7 TeV
We present results on the commissioning of CMS electron reconstruction and identification using the first LHC collisions at √s = 7 TeV recorded by the CMS detector, corresponding to an integrated luminosity of 198 nb{}^{-1}. The electron and photon Level 1 and HLT trigger efficiencies have...

| description | We present results on the commissioning of CMS electron reconstruction and identification using the first LHC collisions at √s = 7 TeV recorded by the CMS detector, corresponding to an integrated luminosity of 198 nb{}^{-1}. The electron and photon Level 1 and HLT trigger efficiencies have been measured from data. The main observables for CMS electron reconstruction, identification, isolation and conversion rejection have been measured and compared to Monte Carlo simulation. The performance of the electron reconstruction and identification has been studied on data. Efficiency and fake rate of different electron selections have been measured and compared to the Monte Carlo expectations. |
