Saturation and Energy Corrections for TeV Electrons and Photons

This note presents a study of the response of the CMS electromagnetic calorimeter ECAL to high energy electrons and photons (from 500 to 4000 GeV), using the full simulation of the CMS detector. The longitudinal containment and the lateral extension of high energy showers are discussed, and energy a...

description This note presents a study of the response of the CMS electromagnetic calorimeter ECAL to high energy electrons and photons (from 500 to 4000 GeV), using the full simulation of the CMS detector. The longitudinal containment and the lateral extension of high energy showers are discussed, and energy and eta dependent correction factors F(E_meas, eta), where E_meas = E_ECAL + E_HCAL, are determined in order to reconstruct the incident particle energy, using the energies measured in the ECAL and in the hadronic calorimeter HCAL. For ECAL barrel crystals with energy deposit higher than 1700 GeV, improvements are proposed to techniques aimed at correcting for the effects of electronics saturation.
