Abstract
Inclusive , and () production is investigated using data recorded by the aleph detector between 1992 and 1994. The momentum spectra and multiplicities are measured separately in , and decays. The number of protons found in b-hadron decays is used to estimate the fraction of b-baryons in b events to be assuming BR(b-baryon. From an additional study of proton-lepton correlations in b events, the branching ratio is obtained. The ratio is found to be .
