Abstract
The production rates of mesons in charm and bottom events
at centre-of-mass energies of about
and the partial width of primary
pairs
in hadronic
decays
have been
measured at LEP using almost 4.4
million hadronic
decays
collected with the OPAL detector between 1990 and
1995.
Using a combination of several charm quark tagging methods based on fully and
partially reconstructed
mesons, and a bottom
tag based on identified muons and electrons,
the hadronisation fractions of charm and bottom
quarks into
mesons have been found to be
and
The fraction of events in hadronic
decays,
,is determined to be
