Jet measurements in CMS

Measurements of jet cross sections in proton collisions with the CMS experiment are presented. Measurements are performed as a function of the jet transverse momentum pT and jet rapidity. Jets are reconstructed using the anti-kT clustering algorithm with different size parameters in a wide phase space region in jet pT and jet rapidity. The measured jet cross sections are corrected for detector effects and compared with the predictions from perturbative QCD.
