| Abstract: A measurement of the double-differential inclusive jet cross section, as a function of jet transverse momentum $p_{\mathrm{T}}$ and absolute jet rapidity $|y|$, is presented. Data from LHC proton-proton collisions at $\sqrt{s}=$ 8 TeV, corresponding to an integrated luminosity of 19.71 fb$^{-1}$, have been collected with the CMS detector. Jets are reconstructed with the anti-$k_{\mathrm{T}}$ clustering algorithm for a jet size parameter R=0.7 in a phase space region covering jet $p_{\mathrm{T}}$ up to 2.5 TeV and jet rapidity up to $|y|=$ 3.0. The measured jet cross section is corrected for detector effects and compared to predictions of perturbative QCD at next-to-leading order using various sets of parton distribution functions. From the measured double-differential jet cross section the strong coupling constant value is found to be $\alpha_{\mathrm{S}}(\mathrm{M_Z}) =$ 0.1164$^{+0.0060}_{-0.0043}$, using the CT10 NLO parton distribution function set. Constraints on parton distribution functions based on the inclusive cross section measurement are presented. | ||
