dc.description.abstract	The production and decay of beauty baryons (b-baryons) have been studied using 1.7×106 Z hadronic decays collected by the DELPHI detector at LEP. Three different techniques were used to identify theb-baryons. The first method used pairs of a Λ and a lepton to tag theb-baryon decay. The second method associated fully reconstructed ΛC baryons with leptons. The third analysis reconstructed theb-baryon decay points by forming secondary vertices from identified protons and muons of opposite sign. Using these methods the following production rates were measured:
