Abstract

We present high statistics measurements of the energy-energy correlation (EEC) and its related asymmetry (AEEC) in e+e- annihilation at a c.m. energy of 34.6 GeV. We find that the energy dependence as well as the large angle behaviour of the latter are well described by perturbative QCD calculations to Oα(s 2). Non-perturbative effects are estimated with the help of fragmentation models in which different jet topologies are separated using (e{open}, δ) cuts, and found to be small. The extracted values of {Mathematical expression} lie between 100 and 300 MeV.
