First Determination of the Strong Coupling Constant from the ttbar Cross Section
Approximate next-to-next-to-leading-order QCD predictions for the cross section of top-quark pair production are used together with different parton distribution functions to extract the strong coupling constant, $\alpha_S$, from the cross section measured by the CMS experiment in proton-proton coll...
