Abstract

Preserving high reconstruction efficiency and best four-momentum measurements down to low p_T for electrons in CMS is a necessity for optimal discovery prospects in the ZZ* and WW* Higgs boson decay channels and in the leptonic decay of charginos and neutralinos. This is challenging in view of the material budget in front of the electromagnetic calorimeter ECAL and the presence of a strong magnetic field. The reconstruction for isolated electrons in CMS is described. The performances of electron identification, combining tracking and calorimetry information, are discussed.
