Inclusive and dijet jet production measured with the ATLAS detector

Inclusive jet and dijet double differential cross sections have been measured in proton proton collisions using the ATLAS detector. The cross sections were measured using jets clustered with the anti−kT algorithm. The data are compared to predictions based on next-to-leading order QCD calculations corrected for non perturbative effects, as well as to next-to-leading order Monte Carlo predictions. Ratios of cross sections measured at different centre of mass energies allow for reduced experimental and/or theoretical uncertainties. An NLO QCD analysis of the data indicates constraining power for the gluon density.
