Abstract: The charmonium and bottomonium spectra computed from a potential defined from a single gauge configuration, obtained from solving the classical field equations, is discussed. The theoretical spectra shows good agreement with the measured states. A discussion of possible interpretations, within the same non-relativistic potential model, for the new charmonia states $X(3872)$, $chi_{c1} (2P)$ and $Y(4260)$ is performed. In particular, we give predictions for electromagnetic E1 transitions for various scenarios.
