- W89309023 abstract "Recent investigations of QCD aspects of heavy quark events in [ital e][sup +][ital e][sup [minus]] collisions are presented. Using three jet fractions in these events the flavor independence of the coupling constant of QCD, [alpha][sub [ital s]], is verified: [alpha][sup [ital b]][sub [ital s]]/[alpha][sup [ital udsc]][sub [ital s]]=1.01[plus minus]0.03[plus minus]0.03. The average scaled energy of charmed and bottom hadrons in decays of the Z[sup 0] is determined. Comparing these results with measurements at lower energies clear evidence for scaling violation is established. Studies of the shape of the fragmentation function do not yet allow a significant discrimination between different theoretical models. A study of the differences between quark and gluon jets performed in a model independent way establishes, that gluon jets are softer and broader compared to quark jets in the same environment." @default.
