| Abstract: A measurement of the double differential inclusive jet cross section as a function of the jet transverse momentum $p_{\mathrm{T}}$ and the absolute jet rapidity $|y|$ is presented. Data from LHC proton-proton collisions at $\sqrt{s}= $ 13 TeV, collected with the CMS detector with an integrated luminosity of 36.3 fb$^{-1}$ (33.5 fb$^{-1}$) are analysed. Jets are reconstructed using the anti-$k_{\mathrm{T}}$ clustering algorithm with size parameters of 0.4 (0.7) in a phase space region covering jet $p_{\mathrm{T}}$ from 97 GeV up to 3.1 TeV and jet absolute rapidity up to $|y|=$ 2.0. The measured jet cross section is corrected for detector effects and compared with the predictions from perturbative QCD. These measurements, together with the multi-differential cross sections of $\mathrm{t\bar{t}}$ production, are used in a comprehensive QCD analysis to extract the parton distribution functions, the strong coupling, and the top quark mass, simultaneously. Using an effective field theory-improved QCD, also the Wilson coefficient of a 4-quark contact interactions model is determined. | ||
