  Inclusive jet and dijet double-differential cross sections have been measured
in proton-proton collisions at a centre-of-mass energy of 7 TeV using the ATLAS
detector at the LHC. The cross sections were measured using jets clustered with
the anti-kt algorithm. The measurements are performed in the jet rapidity range
|y| < 4.4, covering jet transverse momenta from 20 GeV to 1.5 TeV and dijet
invariant masses from 70 GeV to 5 TeV. The data are compared to expectations
based on next-to-leading order QCD calculations corrected for non-perturbative
effects, as well as to next-to-leading order Monte Carlo predictions. The data
test the theory in a new kinematic regime, and provide sensitivity to parton
distribution functions in a region where they are currently not well
constrained.
