Electrons and Photons play a crucial role at LHC in several fields. They provide important signatures for discovery of the Higgs Boson, for discovery of supersymmetry, or for the discovery of new heavy bosons like the Z’. Clean identification and excellent energy and momentum resolution where given high priority in the design of the CMS detector. The instrument, featuring a finely grained, high-resolution electromagnetic calorimeter and excellent tracking performances, is well equipped for the task of measuring these particles with high precision.

Abstract
Electrons and Photons play a crucial role at LHC in several fields. They provide important signatures for discovery of the Higgs Boson, for discovery of supersymmetry, or for the discovery of new heavy bosons like the Z’. Clean identification and excellent energy and momentum resolution where given high priority in the design of the CMS detector. The instrument, featuring a finely grained, high-resolution electromagnetic calorimeter and excellent tracking performances, is well equipped for the task of measuring these particles with high precision. In this contribution we will describe the CMS electron and photon identification and reconstruction capabilities.
