| Abstract: A comprehensive analysis at next-to-next-to-leading order (NNLO) accuracy in quantum chromodynamics (QCD) is presented. It uses double-differential cross section measurements of inclusive jet production from the CMS Collaboration at centre-of-mass energies of 2.76, 7, 8, and 13 TeV. The result is a simultaneous determination of the value of the strong coupling constant at the mass of the Z boson $ \alpha_{\mathrm{s}}(M_{\mathrm{Z}}) $ together with the parton distribution functions of the proton. The value $ \alpha_{\mathrm{s}}(M_{\mathrm{Z}}) = $ 0.1176 $ ^{+0.0014}_{-0.0016} $ is obtained. By using the measurements in different intervals of jet transverse momenta, the running of the strong coupling is probed for energy scales between 100 and 1600 GeV. | ||
