We have determined the strong coupling alpha-s from a comprehensive study ofenergy-energy correlations (EEC) and their asymmetry (AEEC) in hadronic decaysof Z0 bosons collected by the SLD experiment at SLAC. The data were comparedwith all four available predictions of QCD calculated up to O(alpha-s**2) inperturbation theory, and also with a resummed calculation matched to all fourof these calculations. We find large discrepancies between alpha-s valuesextracted from the different O(alpha-s**2) calculations. We also find a largerenormalization scale ambiguity in alpha-s determined from the EEC using theO(alpha-s**2) calculations; this ambiguity is reduced in the case of the AEEC,and is very small when the matched calculations are used. Averaging over allcalculations, and over the EEC and AEEC results, we obtainalpha-s(MZ)=0.124+0.003-0.004(exp.) +-0.009(theory).Comment: 37, SLAC-PUB-645
