The electromagnetic calorimeter of the CMS experiment is designed to reach excellent energy resolution, essential for the discovery of narrow electromagnetic resonances, such as the Standard Model decay H?? ????. The non uniformity of the individual channels directly contributes to the calorimeter energy resolution. While the final performance will be achieved with in situ calibration exploiting physics...
The CMS object oriented Geant4-based program is used to simulate the complete central CMS detector (over 1 million geometrical volumes) and the forward systems such as the Totem telescopes, Castor calorimeter, zero degree calorimeter, Roman pots, and the luminosity monitor. The simulation utilizes the full set of electromagnetic and hadronic physics processes provided by Geant4 and detailed particle...
