Electron reconstruction and identification efficiency measurements with the atlas detector using the 2011 lhc proton-proton collision data

Mostrar todas las versiones(2)

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 √s =...
