摘要
A measurement is presented of the inclusive production of charged D* and neutral D mesons from nonresonant e+e- annihilation in the energy region near the (4S) resonance. The momentum distribution shows a large contribution at high momenta as expected for heavy quark production. Comparison of the spectrum with several phenomenological models is made. The relative yields of the D* and D mesons indicate that the charm cross section is dominated by the D* contribution.
