AbstractAbstract
[en] Energy-energy-correlations (EEC) have been measured with the JADE detector at c.m. energies of 14 GeV, 22 GeV and in the region 29 GeV < Esub(cm) < 36 GeV. Corrected results are presented of EEC and their asymmetry, which can be directly compared to theoretical predictions. At < Esub(cm) > = 34 GeV a comparison with second order QCD predictions yields good agreement for the string model fragmentation resulting in a value of the strong coupling constant αsub(s) = 0.165 +- 0.01 (stat.) +- 0.01 (syst.). The independent fragmentation models, which yield values of αsub(s) between 0.10 and 0.15 depending on the treatment of energy and momentum conservation and of the gluon splitting, do not provide a satisfactory description of the data over the full angular range.
