Abstract

The Mark II detector at SPEAR has been used to study D-meson production in e+e- annihilation at center-of-mass energies between 3.8 and 6.7 GeV. The neutral and charged D mesons are identified from their K and K decay modes. Measurements of RD and of the inclusive differential cross section s ddz are presented. The quasi-two-body cross sections DD, D*D, and D*D* are derived from an overall fit to the D recoil spectra. No evidence was found for the associated production of charmed mesons and charmed baryons. © 1982 The American Physical Society.
