Abstract

Reconstructed Λ baryon decays and photon conversions in DELPHI are used to measure the Σ⁰ production rate from hadronic Z⁰ decays at LEP. The number of Σ⁰ decays per hadronic Z decay is found to be: (Equation presented). The Ω^- production rate is similarly measured to be: (Equation presented) by a combination of methods using constrained fits to the whole decay chain and particle identification.
