Abstract
Following lattice results for the quark-antiquark satic energy when mixing with an open flavor meson-meson configuration is considered, we build a Born-Oppenheimer potential for J^{PC}=1^{--} charmonium states below their first S- wave meson-meson threshold. We show that a good description of the mass and decay properties of the experimentally well established resonances in this spectral region, including conventional states and the unconventional psi(4260), is feasible.
