Description
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. 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.
In addition to a test of the theory in a new kinematic regime, the data also provide sensitivity to
parton distribution functions in a region where they are currently not well-constrained.
