[QUOTE="vanhees71, post: 6279359, member: 260864"] Already the first sentence in the above quoted document makes me a bit puzzled. Particularly in the case of QCD you have to be specific about in which context the strong coupling ##\alpha_{\text{s}}=g^2/(4 \pi)## is measured. The quoted value seems to be a value measured in deep inelastic scattering at energy-transfer scales around the Z-boson mass of around 90 GeV. [/QUOTE]
