They are based on data from LHC proton-proton collisions at root s = 7 TeV corresponding to an integrated luminosity of 5.0 fb(-1) collected with the CMS detector in 2011. The ratio of these two measurements is obtained as a function of the rapidity and transverse momentum of the jets. Significant discrepancies are found comparing the data to leading-order simulations and to fixed-order calculations at next-to-leading order, corrected for nonperturbative effects, whereas simulations with next-to-leading-order matrix elements matched to parton showers describe the data best.eninfo:eu-repo/semantics/openAccessMeasurement of the Ratio of Inclusive Jet Cross Sections Using the Anti-K(t) Algorithm With Radius Parameters R=0.5 and 0.7 in Pp Collisions at Root S=7 TevArticle10.1103/PhysRevD.90.07200610.1103/PhysRevD.90.072006
