A measurement of the calorimeter response to single hadrons and determination of the jet energy scale uncertainty using LHC Run-1 pp-collision data with the ATLAS detector

A measurement of the calorimeter response to isolated charged hadrons in the ATLAS detector at the LHC is presented. This measurement is performed with 3.2 nb - 1 of proton–proton collision data at s=7 TeV from 2010 and 0.1 nb - 1 of data at s=8 TeV from 2012. A number of aspects of the calorimeter...
