The $q\bar{q}$ relativistic interaction in the Wilson loop approach

Abstract

We study the $q\bar{q}$ relativistic interaction starting from the Feynman-Schwinger representation of the gauge-invariant quark-antiquark Green function. We focus on the one-body limit and discuss the obtained non-perturbative interaction kernel of the Dirac equation.
