Molecular Charmonium: A New Spectroscopy?

Recent data compel us to interpret several peaks in the cross section of e/sup -/e/sup +/ annihilation into hadrons as being due to the production of four-quark molecules, i.e., resonances between two charmed mesons. A rich spectroscopy of such states is predicted and may be studied in e/sup -/e/sup +/ annihilation.
