Abstract
A study of the fragmentation properties of charm and bottom quarks int o D mesons is presented. From 263 700 Z0 hadronic decays collected in 1991 with the DELPHI detector at the LEP collider, D0, D+ and D+ are reconstructed in the modes K- pi+, K- pi+pi+ and D0pi+ followed by D0- ->K- pi+, respectively. The fractional decay widths GAMMA(Z0-->D/DXBAR )/GAMMA(h) are determined, and first results are presented for the pro duction of D mesons from ccBAR and bbBAR events separately. The averag e energy fraction of D+/- in charm quark fragmentation is found to be [X(E)(D)]c=0.487+/-0.015 (stat)+/-0.005 (sys.). Assuming that the fr action of D(s) and charm-baryons produced at LEP is similar to that ar ound 10 GeV, the Z0 partial width into charm quark pairs is determined to be GAMMA(c)/GAMMA(h)=0.187+/-0.031 (stat)+/-0.023 (sys). The proba bility for a b quark to fragment into B(s)BAR or b-baryons is inferred to be 0.268+/-0.094 (stat)+/-0.100 (sys) from the measured probabilit y that it fragments into a B0BAR or B-.
