摘要
Precise calibration and alignment of the CMS electromagnetic calorimeter (ECAL) is crucial for achieving excellent ECAL performance required by many physics analyses employing electrons and photons. The methods used to inter-calibrate the ECAL energy response, using physics channels such as W/Z boson decays to electrons and pi(0)/eta decays to photon pairs, and also exploiting the azimuthal symmetry of the minimum bias events are presented here. In addition, the details of the alignment procedure used to calibrate the position measurements in ECAL relative to the CMS Tracker is also described. Lastly, results of the calibration and alignment obtained with Run 2 data are presented.
