Measurement of the inclusive jet cross section in pp collisions at √sNN=2.76TeV

Abstract

The double-differential inclusive jet cross section is measured as a function of jet transverse momentum pTand absolute rapidity |y|, using proton-proton collision data collected with the CMS experiment at the LHC, at a center-of-mass energy of s√=2.76TeV and corresponding to an integrated luminosity of 5.43pb−1. Jets are reconstructed within the pTrange of 74 to 592GeVand the rapidity range |y|<3.0. The reconstructed jet spectrum is corrected for detector resolution. The measurements are compared to the theoretical prediction at next-to-leading-order QCD using different sets of parton distribution functions. This inclusive cross section measurement explores a new kinematic region and is consistent with QCD predictions.
