Abstract
The b quark semi-leptonic branching ratios are measured using the hadronic events containing one or two leptons. 950 000 Z{sup 0} hadronic disintegrations were obtained in the DELPHI experiment during 1991-1992. Thus one of the elements of the CKM matrix may be determined. Using information contained in hadron jets with two opposite-sign leptons, the cascade ratios of the beauty hadron semi-leptonic disintegrations are evaluated. The baryon production rate in beauty events is analyzed, and the charmed Lambda baryon production cross-section is measured. 93 figs., 23 tabs., 75 refs.
