Abstract

We have studied momentum spectra for D0 (D0) and D± mesons produced near 4 GeV in e+e- annihilation and find that production is dominated by two-body reactions involving D and D* states where the D* (charged and neutral) have masses near 2.01 GeV/c2. A detailed study of D momentum spectra near Ecm = 4.028 GeV allows determination of masses and branching ratios of D and D* states. Lastly we find that events containing a D0 meson conserve strangeness, thus establishing upper limits on D0-D0 mixing and on the effects of charm changing neutral currents.
