Abstract
Multihadronic events measured with the CELLO detector in the energy range 14 to 46 GeV have been analyzed in terms of thrust, jet masses and the asymmetry of the energy-energy correlation. The data have been compared with 2nd order QCD calculations. From a study of the general properties of fragmentation effects, model-independent limits on ΛQCD and α s have been found to be 79 MeV < ΛQCD < 628 MeV and 0.117 < α s < 0.169 (at\(\sqrt s = 35\) GeV). The dependence of these results on the renormalization scheme is discussed.
