Description

Electron-positron-annihilations into hadrons were observed in the region of the UPSILON(9.46 GeV) and the UPSILON' (10.02 GeV) resonances at the storage ring DORIS with the nonmagnetic NaI lead-glass detector. Distributions of sphericity and charged multiplicity were measured. Outside the resonances the data show a clear two-jet structure, while the decays of the resonances are compatible with the predictions of a three-gluon model. (orig.)
