Phys. Rev. D 37, 1719–1743 (1988)Charm production in nonresonant e+e- annihilations at √s =10.55 GeVSee Also: Erratum Received 26 October 1987; published in the issue dated 1 April 1988 We report results on the differential and total cross sections for inclusive production of the charmed particles D*+, D*0, D0, D+, Ds, and Λc in e+e- annihilations at √s=10.55 GeV. Widely used quark fragmentation models are discussed and compared with the measured charmed-particle momentum distributions. This comparison, as well as that with measurements at other center-of-mass energies, shows the need to take QCD corrections into account and their importance for a correct interpretation of the model parameters. The observed rate of D0 and D+ production is compared to the expected total charm production cross section. We measure the probability of a charmed meson being produced as a vector meson and the D*+ decay branching fraction into D0π+. © 1988 The American Physical Society URL:
