Abstract

The theoretical derivation from QCD of the {Mathematical expression} potential with velocity-dependent corrections is reconsidered. In particular the problem of ordering between momenta and functions of position in the Hamiltonian is discussed and exact relations among the various potentials are derived. Explicit expressions for the long-range behaviour of the potentials are given, the effect of the velocity-dependent corrections on the quarkonium spectrum is evaluated and compared with the results obtained by different proposals based on more heuristic considerations.
