AbstractAbstract
[en] Electron identification at CDF is performed using the information of lateral and longitudinal shower spread, the track-cluster position match and the energy-momentum match. The tracking chamber with a solenoidal magnetic field at CDF is useful for rejecting the backgrounds such as the π±-π0 overlaps, the π0 /γ conversions and interactive π± in electromagnetic calorimeter: The energy-momentum match cut can decrease the background due to the π±-π0 overlaps for non-isolated electrons with Et above 10 GeV by a factor of 20. The conversion electrons are identified using track information with an efficiency of 80 ± 3 %. The charge of electrons from W decay can be determined in the pseudorapidity range of | η | < 1.7 at CDF. The charge determination is important for background estimation of Drell-Yan physics and heavy flavour physics. (author)
