Abstract

We study the relativistic description of heavy qqBAR bound states in the context of the relativistic wave equation. We used some attractive QCD based potentials where the vector part incorporates in the two loop perturbation QCD effects at short distances while the scalar part approaches the linear confining potential at large distances. We calculate the energy levels, leptonic and hadronic decay widths, as well as the E1 rate transition for ccBAR and bbBAR. Results are compared with their experimental values.
