In-situ pseudo-rapidity inter-calibration to evaluate jet energy scale uncertainty and calorimeter performance in the forward region

The response of the ATLAS calorimeters to jets is studied by balancing the transverse momenta of dijets in pp collisions at sqrt(s)=7 TeV using 17nb-1 of integrated luminosity. The results indicate that the jet response, measured relative to a central reference region, is understood to better than 2...

description The response of the ATLAS calorimeters to jets is studied by balancing the transverse momenta of dijets in pp collisions at sqrt(s)=7 TeV using 17nb-1 of integrated luminosity. The results indicate that the jet response, measured relative to a central reference region, is understood to better than 2% for jets with |eta|<1.8, to better than 5% in the region 1.8<|eta|<2.8 and to approximately 10% in the region |eta|>2.8. The properties of jets that are reconstructed in the forward calorimeters are also measured.
