title = "D meson production and decay in e+e- annihilation at 4.03 and 4 GeV c.m. energy",
abstract = "Decay modes of the charmed mesons, D0 and D+, are studied in e+e- annihilation data at 4.03 and 4.41 GeV c.m. energy. The products of cross section times branching ratio are measured for the K-π+, K-π+π+π-, KSπ+π- and K-π+π+ final states. Upper limits are established for the Cabibbo forbidden decays via π+π-, K+K-, K+K- π+, K+π+π- and π+π-π+. The K-π+π+π- final state is shown to be dominated by K-π+ρ0.",

note = "In previous pubhcations \textbackslash{}[1,2\textbackslash{}],w e have estabhshed the existence of the charmed mesons D O and D +. The evidence for these new particles was found in a study of multihadron production from e+e - annihilation at c.m. energies above 4 GeV. To investigate the production and properties of these new mesons in some detail, we have collected large samples of data at energies where the multi-hadron annihilation cross section has maxima, namely 4.03 and 4.41 GeV \textbackslash{}[3\textbackslash{}].S amples of about 27000 and 25 000 hadronic events, corresponding to luminosities of 1270 nb -1 and 1630 nb -1 respectively, were recorded at these two energies. In this paper we present measurements of the products oB of cross section times branching ratio for several D O and D + decay modes at 4.03 and 4.41 GeV.
