Measurements of the braching fractions for psi(3770)--> D0D0-bar,D+D-,DD-bar$ and the resonance parameters of psi(3770) and psi(2S)

M. Ablikim et al.

We report measurements of the branching fractions for $\psi (3770)\to D^0{\bar{D}}^0,D^{+}{D}^{-},D\bar{D}$ and resonance parameters of $\psi (3770)$ and $\psi (2S)$. By analyzing the line-shapes of…
