Analysis of the $\psi (4040)$ and $\psi (4160)$ decay into $D^{(\ast )}{\bar{D}}^{(\ast )}$, $D_s^{(\ast )}{\bar{D}}_s^{(\ast )}$

We have performed an analysis of the $e^{+}{e}^{-}\to D^{(\ast )}{\bar{D}}^{(\ast )}$ data in the region of the $\psi (4040)$ and $\psi (4160)$ resonances which have a substantial overlap and require sp…
