Possible new resonance at the $D^{\ast }{\bar{D}}^{\ast }$ threshold in $e^{+}{e}^{-}$ annihilation

Abstract

We argue that the recent CLEO-c data on $e^{+}{e}^{-}$ annihilation into pairs of charmed mesons at c.m. energy around 4.0 GeV are not well described by a single resonance $\psi (4040)$, but can be better understood if there is an additional narrow resonance with mass within few MeV from the $D^{\ast }{\bar{D}}^{\ast }$ threshold.
