  Measurements of inclusive jet and dijet production cross sections are
presented. Data from LHC proton-proton collisions at sqrt(s) = 7 TeV,
corresponding to 5.0 inverse femtobarns of integrated luminosity, have been
collected with the CMS detector. Jets are reconstructed up to rapidity 2.5,
transverse momentum 2 TeV, and dijet invariant mass 5 TeV, using the anti-kt
clustering algorithm with distance parameter R = 0.7. The measured cross
sections are corrected for detector effects and compared to perturbative QCD
predictions at next-to-leading order, using five sets of parton distribution
functions.
