Description
Summary:A systematic method of deriving the quark-antiquark potential is developed. The whole procedure is organized as a 1/c expansion. Up to order 1/c2, the Eichten-Feinberg spin-dependent potential is recovered and new velocity-dependent terms are obtained. As essential step of the derivation is the identification of a Pauli-type two-particle propagator, which satisfies a suitable Schrödinger equation. The short- and large-distance behaviour of the potentials is studied.
