Abstract
The production of prompt muons in e+e- annihilation has been studied at centre of mass energies near 34.5 GeV. The measured semi-muonic branching ratios of b and c quarks are B(b»Xμv) =0.117±0.028±0.01 and B(c→Xμv)=0.082 ±0.012a-0.01+0.02. The fragmentation functions of heavy quarks are hard, b>=0.85a-0.12-0.07+0.10+0.02 and c> =0.77a-0.07-0.11+0.05+0.03. Limits have been set on flavour changing neutral current decays:B(b→Xμ+μ-) +μ- (95% confidence level).
