Abstract: From lattice indications we follow a Born-Oppenheimer approximation to build a quark-antiquark static 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 psi(4260) resonance is feasible.

Abstract: We show that a good description of the Upsilon(10860) properties, in particular the mass, the e(+) e(-) leptonic widths and the pi(+) pi(-) Upsilon(ns) (n = 1, 2, 3) production rates, can be obtained under the assumption that Upsilon(10860) is a mixing of the conventional Upsilon(5s) quark model state with the lowest P-wave hybrid state.
