Description
Starting from the QCD Lagrangian and taking into account both perturbative and nonperturbative effects, the method of vacuum correlators to derive the Dirac equation (rigorously for the Coulomb interaction and heuristically for the confining potential) for a system consisting of a light quark and heavy antiquark is used. As a result the confining potential is a Lorentz scalar, and the Coulomb part is the fourth component of a 4-vector. The energy spectrum of the Dirac equation is considered for these potentials
