| Measurement of the double-differential inclusive jet cross section at √s= 13 TeV | ||
| CMS Collaboration | ||
| December 2015 | ||
| Abstract: A measurement of the double-differential inclusive jet cross section, as a function of jet transverse momentum pT and absolute jet rapidity |y|, is presented. The analysis is based on a data set of proton-proton collisions acquired by the CMS experiment at the LHC during 2015 at a center-of-mass energy of 13 TeV. The collected data correspond to an integrated luminosity of 72 pb−1 for rapidities up to |y|= 3 and 45 pb−1 for the forward rapidity region 3.2 <|y|< 4.7. Jets are reconstructed with the anti-kT clustering algorithm for two jet size parameters R= 0.7 and R= 0.4 in a phase space region covering jet pT up to 2 TeV and jet rapidity up to |y|= 4.7. The results are compared to fixed-order predictions of perturbative QCD and to simulations using various Monte Carlo event generators including parton showers, hadronisation, and multiparton interactions. | ||
