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 particles. 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 component from fragmentation and the component coming from the decay of b-hadrons. The measurement of the average charge multiplicity in <b(b)over bar> events was used to compute the mean fractional beam energy carried by the primary b-hadron, and the difference in charged particle multiplicity between <b(b)over bar> events and light quark (<u(u)over bar>, <d(d)over bar>, <s(s)over bar>) events.
