Measurement of αs from energy-energy correlations at the Z0 resonance
Abstract
We determine the strong coupling αs from a comprehensive study of energy-energy correlations (EEC’s) and their asymmetry (AEEC’s) in hadronic decays of Z0 bosons collected by the SLD experiment at SLAC. The data are compared with all four available predictions of QCD calculated up to O(αs2) in perturbation theory, and also with a resummed calculation matched to all four of these calculations. We find large discrepancies between αs values …
