Description

Momentum spectra have been studied for D0 (anti D0) and D+- mesons produced near 4 GeV in e+e- annihilation and it is found 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 Esub(cm)=4.028 GeV allows determination of masses and branching ratios of D and D* states. Lastly it is found that events containing a D0 meson conserve strangeness, thus establishing upper limits on D0-anti D0 mixing and on the effects of charm changing neutral currents. (Auth.)
