Abstract

The relative production ratio of 3-jet events to the total number of hadronic events was studied in e+e- annihilations at centre-of-mass energies between 54 and 61.4 GeV. The QCD scale parameter has been determined to be ΛMS=254-47+55±56 MeV on the basis of a QCD cascade with the next-to-leading logarithmic approximation.
