英文摘要Based on the data of BES and Belle, the production of D (D) over bar in the e(+)e(-) -> D (D) over bar scattering process is studied in this paper. We analyze the continuum and resonant contributions in the energy region from 3.7 to 4.4 GeV. In the chi(2) fit to data, we obtain the resonance parameters of c psi(3770), the branching ratio of psi(3770) -> D (D) over bar decay by confronting the data to the theoretical formula where both the contributions of the resonances, continuum and interference effects are included. We obtain the branching ratio of psi(3770) -> D (D) over bar decay is 97: 2% +/- 8: 9%, as well as the branching ratio of psi(4040), psi(4160) -> D (D) over bar decays.
