Electron reconstruction and identification efficiency measurements with the ATLAS detector using the 2011 LHC proton–proton collision data

다국어 초록 (Multilingual Abstract)

<P>Many of the interesting physics processes to be measured at the LHC have a signature involving one or more isolated electrons. The electron reconstruction and identification efficiencies of the ATLAS detector at the LHC have been evaluated using proton–proton collision data collected in 2011 at [FORMULA OMISSION] TeV and corresponding to an integrated luminosity of 4.7 fb[FORMULA OMISSION]. Tag-and-probe methods using events with leptonic decays of [FORMULA OMISSION] and [FORMULA OMISSION] bosons and [FORMULA OMISSION] mesons are employed to benchmark these performance parameters. The combination of all measurements results in identification efficiencies determined with an accuracy at the few per mil level for electron transverse energy greater than 30 GeV.</P>
