Abstract

Using the ARGUS detector at the e+e storage ring DORIS II at DESY, we have measured the inclusive production of D0, D+ and D*(2010)+ mesons inB decays and in nonresonant e+e annihilation around 10.6 GeV. The inclusive branching ratios forB decays to D0, D+ and D*+ mesons are found to be (52.2±8.2±3.5)%, (27.2±6.3±3.5)% and (34.8±6.0±3.5)% respectively. Thus, D0 and D+ production account for about 70% of the charm produced in B decays, neglectingbu contributions to the total width. The production cross sections and momentum spectra for continuum e+e annihilation are also presented.
