Electron identification at CDF

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 powerful for rejecting the backgrounds such as the {pi}{sup {plus minus}} {minus} {pi}{sup 0} overlaps, the {pi}{sup 0}/{gamma} conversions and interactive {pi}{sup {plus minus}} in electromagnetic calorimeter: The energy- momentum match cut can decrease the background due to the {pi}{sup {plus minus}} {minus} {pi}{sup 0} 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 {plus minus} 3%. The charge of electrons from W decay can be determined in the pseudorapidity range of {vert bar}{eta}{vert bar} < 1.7 at CDF. The charge determination is useful for background estimation of Drell-Yan physics and heavy flavor physics. 5 refs., 5 figs
