QCD POTENTIOLOGY

We review the connection between QCD and potential models of quarkonia in the framework of effective field theories, with an emphasis on non-perturbative methods such as lattice simulations. The static and heavy quark potentials are introduced and the applicability of the non-relativistic and adiabatic approximations are discussed. The rôles of so-called hybrid potentials are explored and we comment on the QCD analogue of the QED Lamb shift.
