Production of C and B flavored mesons and their decays at LEP

The production rates of D-0, D+, D-s(+), Lambda(c), D*(+), D*(0), D-s*(+), D** and D-s** hadrons in Z(0) --> c (c) over bar and Z(0) --> b (b) over bar measured by the LEP collaborations are presented. The measurements of the number of produced charm quarks in b-hadron decays and the partial width of the Z(0) going into a charm quark pair Gamma c (c) over bar/Gamma (c) over bar(had) derived from charm production rates are discussed. The LEP measurements of the semileptonic branching ratio Br(B--> l) are compared with results from CLEO and with recent theoretical calculations. From the production rates of pseudoscalar and vector mesons the ratio V/(V+P) in the D and the D-s sectors are determined and the results are compared with simple spill counting predictions. Finally the first observation of the radially excited D*' meson is discussed.
