Abstract
Reconstructed ii baryon decays and photon conversions in DELPHI are used to measure the Sigma(0) production rate from hadronic Z(0) decays at LEP. The number of Sigma(0) decays per hadronic Z decay is found to be: > = 0.070 +/- 0.010 (stat.) +/- 0.010 (syst.). The Omega(-) production rate is similarly measured to be: = 0.0014 +/- 0.0002 (stat.) +/- 0.0004 (syst.) by a combination of methods using constrained fits to the whole decay chain and particle identification.
