## Abstract

Results on K^{0} and Λ production in e^{+}e^{-} annihilation at c.m. energies of 14, 22 and 34 GeV are presented. The shape of the K^{0} 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 K^{0} 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 R^{h}=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 K^{0} and 0.31±0.03 Λ per event. We have searched for possible Λ polarization. The production of K^{0}'s and Λ's in jets is examined as a function of p_{T}^{2} 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.
