| Abstract: Measurements of the inclusive jet cross section with the anti-k$_{T}$ clustering algorithm are presented for two radius parameters, $R=0.5$ and $R=0.7$. The data from LHC proton-proton collisions at $\sqrt{s}$ = 7 TeV, corresponding to 5.0 fb$^{-1}$ of integratedluminosity, have been collected with the CMS detector. The ratio of the two measurements is derived as a function of the rapidity and transverse momentum of the jets. Significant discrepancies are found comparing the data to LO simulations and to fixed order calculations at NLO, corrected for non-perturbative effects, whereas simulations with NLO matrix elements matched to the parton showers describe the data quite well. This result is an indication of the importance of final state radiation in the description of the inclusive jet cross section with small radius parameter such as $R = 0.5$. | ||
