Abstract

Calibration of absolute jet energy scale in CMS experiment at \(\sqrt s = 7\) TeV using the W-mass constraint in t \(\bar t\) -events with W → q \(\bar t\) decay is made. Data sample with an integrated luminosity of 3 fb−1 is used. Calibration procedure is made for calorimetric jets, “Jet-Plus-Track” jets, and “Particle-Flow” jets. Statistical errors of calibration as well as systematical uncertainties of the method are up to 3%. The results are abstracted from degree thesis.
