The inclusive jet cross section for proton-proton collisions at a centre-of-mass energy of 7$~\mathrm{TeV}$ was measured by the CMS Collaboration at the LHC with data corresponding to an integrated luminosity of 5.0$~\mathrm{fb}^{-1}$. The measurement covers a phase space up to 2$~\mathrm{TeV}$ in jet transverse momentum and 2.5 in absolute jet rapidity. The statistical precision of these data leads to stringent constraints on the parton distribution functions of the proton. The data provide important input for the gluon density at high fractions of the proton momentum and for the strong coupling constant at large energy scales. Using predictions from perturbative quantum chromodynamics at next-to-leading order, complemented with electroweak corrections, the constraining power of these data is investigated and the strong coupling constant at the Z boson mass $M_{\mathrm{Z}}$ is determined to be $\alpha_S(M_{\mathrm{Z}}) = 0.1185 \pm 0.0019\, (\mathrm{exp})\, ^{+0.0060}_{-0.0037}\, (\mathrm{theo})$, which is in agreement with the world average.

Concepts and results of determinations of the strong coupling in hadron collisions are discussed. A recent [alpha]{sub s} result from the inclusive jet cross section in p{bar p} collisions at √s = 1.96 TeV is presented which is based on perturbative QCD calculations beyond next-to-leading order. Emphasis is put on the consistency of the conceptual approach. Conceptual limitations in the approach of extracting as from cross section data are discussed and how these can be avoided by using observables that are defined as ratios of cross sections. For one such observable, the multijet cross section ratio R32, preliminary results are presented.

The inclusive jet cross section is measured in pp collisions with a center-of-mass energy of 7 TeV at the LHC using the CMS experiment. The data sample corresponds to an integrated luminosity of 34 inverse picobarns. The measurement is made for jet transverse momenta in the range 18-1100 GeV and for absolute values of rapidity less than 3. The measured cross section extends to the highest values of jet pT ever observed and, within the experimental and theoretical uncertainties, is generally in agreement with next-to-leading-order perturbative QCD predictions.
