Abstract

Abstract: The production of strange baryons ine <superscript>+</superscript> e <superscript>–</superscript> annihilation has been studied at centre of mass energies of 34.8 GeV and 42.1 GeV, using the TASSO detector at DESY. Inclusive cross-sections have been obtained for$$\begin{gathered} \hfill \\ 0.218_{ - 0.011}^{ + 0.011} \pm 0.021 \hfill \\ \end{gathered} $$ and $$0.256_{ - 0.029}^{ + 0.030} \pm 0.025$$ at $$\sqrt s = 34.8$$ and 42.1 GeV respectively. The $$0.014_{ - 0.003}^{ + 0.003} \pm 0.004$$ at $$\sqrt s = 34.8 GeV$$ . An investigation has been made of the extent to whichLambda<superscript>0</superscript> are produced in pairs. TheLambda<superscript>0</superscript> cross-section has been studied as a function of event sphericity.
