Jet energy measurement and its systematic uncertainty in proton-proton collisions at s = 7 TeV with the ATLAS detector

Popis výsledku v původním jazyce

The jet energy scale (JES) and its systematic uncertainty are determined for jets measured with the ATLAS detector using proton?proton collision data with a centre-of-mass energy of s=7 TeV corresponding to an integrated luminosity of 4.7 fb 1 . Jets arereconstructed from energy deposits forming topological clusters of calorimeter cells using the anti- kt algorithm with distance parameters R=0.4 or R=0.6 , and are calibrated using MC simulations. A residual JES correction is applied to account for differences between data and MC simulations. This correction and its systematic uncertainty are estimated using a combination of in situ techniques exploiting the transverse momentum balance between a jet and a reference object such as a photon or a Z boson,for 20pjetT<1000 GeV and pseudorapidities |?|<4.5 . The effect of multiple proton?proton interactions is corrected for, and an uncertainty is evaluated using in situ techniques.
