Abstract

We present evidence for the production of Ξ·-, Ξ- in e+e- annihilation into hadrons. Our measurements yields: 0.026 ± 0.008 (stat.) ± 0.009 (syst.) Ξ-- per hadronic event at W ∼ 34 GeV. Using our previous measurements of Λ, Λ and p,p production we obtain the relative yields (Ξ-, Ξ-/(Λ, Λ = 0.087 ± 0.03 (stat.) ± 0.03 (syst.) and (Ξ-, Ξ-/(p, p = 0.033 ± 0.011 (stat.) ± 0.011 (syst.).
