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 ψ(4040), but can be better understood if there is an additional narrow resonance with mass within few MeV from the [Formula: see text] threshold.
