Jet energy scale measurements and their systematic uncertainties in proton-proton collisions at vs=13??TeV with the ATLAS detector

Jet energy scale measurements and their systematic uncertainties are reported for jets measured with the ATLAS detector using proton-proton collision data with a center-of-mass energy of vs=13??TeV, corresponding to an integrated luminosity of 3.2??fb-1 collected during 2015 at the LHC. Jets are reconstructed from energy deposits forming topological clusters of calorimeter cells, using the anti-kt algorithm with radius parameter R=0.4. Jets are calibrated with a series of simulation-based corrections and in situ techniques. In situ techniques exploit the transverse momentum balance between a jet and a reference object such as a photon, Z boson, or multijet system for jets with 200.8) is derived from dijet pT balance measurements. For jets of pT=80??GeV, the additional uncertainty for the forward jet calibration reaches its largest value of about 2% in the range |?|>3.5 and in a narrow slice of 2.2<|?|<2.4.
