Abstract

A procedure is presented for evaluating the jet energy scale from direct photons in γ+jet events. The systematic shifts obtained on the jet energy scale with this technique are estimated. The range of applicability of this channel to calibrate the data is also discussed. The study is conducted using fully simulated events passed through the CMS detector including the effects of pile-up at an instantaneous luminosity of ℒ=2×10³³ cm^-2s^-1.
