Abstract

Based on experimental results from CESR and from SLAC’s crystal ball, charmonium (cc) and upsilon (bb) systems are analysed, by using a phenomenological confinement approach. We show that the potentialKr1/2 — (4/3)αs/r +C describes adequately the spectroscopy of the two families mantaining the 4.414 GeV state as charmonium’s 43S1. The dependence of the potential on flavour is also discussed.
