Abstract
Proc. of DIS 2012, 223-226; DESY
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-$k_{t}$ algorithm. The
measurements are performed in the jet rapidity range $\vert{\rm y}\vert < 4.4$,
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.
