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

High Energy Physics - Phenomenology 2008-11-26 v1

Abstract

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