[en] F dynamical mechanism for the production of baryons in e⁺e^- annihilations both on and off the upsilon resonance is presented. Parton showers are produced using an approximation to QCD perturbation theory. Color singlet clusters are formed and 'decay' into hadrons through a simple phase-space process. Baryon-antibaryon pairs are produced in the decay of high mass clusters and are more abundant at the upsilon since the initial state of three gluons results in more high mass clusters than does the quark-antiquark initial state of the continuum.
