The strong coupling constant is computed from three-loop lattice perturbation theory for eight Wilson loops and six Creutz ratios. Three lattice spacings of the MILC 2+1 unquenched lattice data sets were used to perform a continuum extrapolation and estimate the higher order corrections. The light q
Recent results for the cross section of electron-positron annihilation into hadrons and for the decay rates of the Z-boson and the Ο -lepton into hadrons including corrections of order Ξ± 4 s are reviewed. The consistency between two values of Ξ±s measured at vastly different energies constitutes a st
