Charmed meson production by e+e- annihilation

Compelling evidence is presented for the production of the lying (D0, D+) isodoublet of charmed mesons by e+e- annihilation. A study of the recoil mass spectra against these mesons reveals the presence of more massive charmed states, the D*0 and D*+, produced in association with the D isodoublet. Mass values and upper limits on the width of the D and D* are established, and the branching fractions for several D* decay modes are obtained. An analysis of the production and decay angular distributions shows that the D is probably a pseudoscalar state and the D* is probably a vector. Finally, upper limits are obtained for D0-antiD0 mixing
