Description
The electromagnetic calorimeter (ECAL) of the CMS experiment at LHC plays has a crucial role in various physics analyses, spanning from Higgs measurements to the exploration of new physics phenomena. Achieving optimal resolution for electron and photon energy measurements, as well as accurately assessing the electromagnetic component of jets and quantify missing transverse energy, necessitates precise calibration of the detector and its individual channels. To maintain stable energy response over time, a laser monitoring system is utilized to detect radiation-induced alterations in the detector, compensating for them at the reconstruction stage. Moreover, each channel undergoes in-situ calibration using physics events (W and Z electrons, photons from low mass resonance decays). This contribution will describe the methodologies employed for ECAL energy and new time calibration algorithms used by CMS; in addition the new automated system designed to streamline calibration workflows during data taking will be introduced. Finally we'll present the ECAL performance during LHC Run3.
