Description

Results on hyperon production are reported for data accumulated at 10 GeV centre-of-mass energy with the ARGUS detector. Signals for both the octet states Λ, Σ0 and Ξ- and the decuplet states Σ±(1385), Ξ0(1530) and Ω- are observed (references to a specific state are to be interpreted as also implying the charge conjugate state), some for the first time in e+e- annihilation. Baryon rates from Υdir (1S) decays are enhanced by a factor of about 3 over the continuum. (orig.)
