Abstract

Results on K0 and Λ production in e+e- annihilation at c.m. energies of 14, 22 and 34 GeV are presented. The shape of the K0 and Λ differential cross sections are very similar to each other and to those of π±, K± and {Mathematical expression}. Scaling violations are observed for K0 production. We obtain a value for the probability to produce strange quark-antiquark pairs relative to that to produce up or down quark-antiquark pairs of 0.35±0.02±0.05. The value of Rh=σ(e+e-→hX)/σ μμ is shown to rise steadily with c.m. energy for all particle species. At 34 GeV we find 1.48±0.05 K0 and 0.31±0.03 Λ per event. We have searched for possible Λ polarization. The production of K0's and Λ's in jets is examined as a function of pT2 and rapidity and compared to that of all charged particles; the yields in two and three jets are also investigated. Results are presented from events with two baryons {Mathematical expression} observed.
