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 φ(4040), but can be better understood if there is an additional narrow resonance with mass within few MeV from the D* D̄* threshold.
