Baryon production in ALEPH
  Several recent results of the ALEPH Collaboration covering different aspects of baryon production on the Z resonance are presented. In particular production rates of hyperons, the full kinematical reconstruction of the Lambda_b, observation of Xi_b in its semileptonic decay, and the measurements of the polarization of Lambda and Lambda_b baryons are discussed.
