Abstract
Fragmentation functions for charged particles in Z(0) --> q (q) over bar ev ents have been measured Tor bottom (b), charm ic) and light (uds) quarks as well as for all flavours together. The results are based un data recorded between 1990 and 1995 using the OPAL detector at LEP. Event samples with di fferent flavour composition were formed using reconstructed D*(+/-) mesons and secondary vertices. The xi(p) = In(1/x(p)) distributions and the positi on of their maxima xi(0) are also presented separately for uds, c and b qua rk events. The fragmentation function for b quarks is significantly softer than for uds quarks.
