Abstract
A sample of events enriched in <b(b)over bar> quark pairs was selected in the data recorded by the DELPHI experiment at LEP during 1992 and 1993, by the presence of secondary decay vertices from short-lived par ticles. Using this sample, the average multiplicities of K-S(0), K-+/- , p((p) over bar), Lambda(<(Lambda)over bar>) and of charged particles in <b(b)over bar> events have been measured, distinguishing the compo nent from fragmentation and the component coming from the decay of b-h adrons. The measurement of the average charge multiplicity in <b(b)ove r bar> events was used to compute the mean fractional beam energy carr ied by the primary b-hadron, and the difference in charged particle mu ltiplicity between <b(b)over bar> events and light quark (<u(u)over ba r>, <d(d)over bar>, <s(s)over bar>) events.
