Jet energy resolution in proton-proton collisions at [equation] recorded in 2010 with the ATLAS detector

摘要

The measurement of the jet energy resolution is presented using data recorded with the ATLAS detector in proton-proton collisions at (sqrt{s}=7mbox{ TeV}). The sample corresponds to an integrated luminosity of 35?pb?1. Jets are reconstructed from energy deposits measured by the calorimeters 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 uncertainties. 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 resolution agrees with the data within?10?%.
