Hidden charm dynamically generated resonances and the $e^{+}{e}^{-}\to J/\psi D\bar{D}$, $J/\psi D{\bar{D}}^{\ast }$ reactions

D. Gamermann, E. Oset

We analyze two recent reactions of Belle, producing $D\bar{D}$ and $D{\bar{D}}^{\ast }$ states that have an enhancement of the invariant $D\bar{D}$, $D{\bar{D}}^{\ast }$ mass distribution close to thr…
