Abstract
We determine the strong coupling alpha(s) from a comprehensive study o f energy-energy correlations (EEC) and their asymmetry (AEEC) in hadro nic decays of Z(0) bosons collected by the SLD experiment at SLAC. The data are compared with all four available predictions of QCD calculat ed up to O(alpha(s)(2)) in perturbation theory, and also with a resumm ed calculation matched to all four of these calculations. We find larg e discrepancies between alpha(s) values extracted from the different O (alpha(s)(2)) calculations. We also find a large renormalization scale ambiguity in alpha(s) determined from the EEC using the O(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 a ll calculation, and over the EEC and AEEC results, we obtain alpha(s)( M(Z)(2)) = 0.124(-0.004)(+0.003)(expt.)+/-0.009(theory).
