Production of $D^{(\ast )}{\bar{D}}^{(\ast )}$ near the thresholds in $e^{+}{e}^{-}$ annihilation

S. G. Salnikov, A. I. Milstein

It is shown that the nontrivial energy dependencies of $D\bar{D}$, $D{\bar{D}}^{\ast }$, and $D^{\ast }{\bar{D}}^{\ast }$ pair production cross sections in $e^{+}{e}^{-}$ annihilation are well desc…
