摘要
An update of measurements of the strong coupling constant is given, representing the status of September 2002. The results convincingly prove the energy dependence of and are in excellent agreement with the expectations of Quantum Chromodynamics, QCD. Evolving all results to the rest energy of the boson, the new world average of is determined from measurements which are based on QCD calculations in complete NNLO perturbation theory, giving
