Özet

Measurements of inclusive jet and dijet production cross sections are presented. Data from LHC proton-proton collisions at root s = 7 TeV, corresponding to 5.0 fb(-1) 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-k(T) 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.
