Description

Differential jet cross sections and distributions have been measure inclusively, in dijet events and in multijet events, using information from the ATLAS calorimeters and tracking detectors. The inclusive jet measurements extend from 20 GeV to 1.5 TeV, and the dijet measurements cover a very wide mass range. Measurements based on tracking alone are sensitive only to the charged-particle content of the jet, but all accurate measurements down to low transverse momentum, where the onset of hard scattering can be studied as jets emerge from some scattering events. A wide range of QCD-based calculations is confronted with the data, ranging from soft physics models the high multiplicity partonic matrix elements and NLO QCD calculations matched to parton shower simulations, testing the understand of QCD in a new kinematic range.
