Abstract

The measurement of the jet energy resolution is presented using data recorded with the ATLAS detector in proton-proton collisions at √ s = 7 TeV. The sample corre- sponds to an integrated luminosity of 35 pb − 1 . Jets are re- constructed from energy deposits measured by the calorime- ters and calibrated using different jet calibration schemes. The jet energy resolution is measured with two different in situ methods which are found to be in agreement within un- certainties. The total uncertainties on these measurements range from 20 % to 10 % for jets within | y | < 2 . 8 and with transverse momenta increasing from 30 GeV to 500 GeV. Overall, the Monte Carlo simulation of the jet energy reso- lution agrees with the data within 10 %.
