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.
