Abstract

The production of $Λ$ hyperons in $e^{+} e^{-}$ annihilation has been measured as a function of their total momenta, transverse momenta, and the event thrust. The total production rate is 0.213±0.012±0.018 $Λ$ or $\bar{Λ}$ per hadronic event. The observation of correlations in rapidity and angles for events with two detected $Λ$ decays supports fragmentation models with local baryon-number compensation.
