Description
In this paper an investigation of the production of D*± mesons produced in e+e- collisions at energies around the Z0 pole is presented. Based on 115 D*± mesons with xD* = 2ED*/Ecm > 0.2 the properties of D* mesons produced in the reaction Z0 → canti c are studied. Fixing the yield and the fragmentation function of bottom quarks to the values obtained at LEP using lepton tags, an average energy fraction of the D*± mesons from primary charmed quarks of = 0.52±0.03±0.01 is found and Γsub(Z0→canti c) = (323±61±35) MeV is determined. The first error is the combined statistical and systematic error from this experiment, and the second the total error from other sources. (orig.)
