From the Feynman-Schwinger representation to the non-perturbative relativistic bound state interaction
Description: The authors write the 4-point Green function in QCD in the Feynman-Schwinger representation and show that all the dynamical information are contained in the Wilson loop average. They work out the QED case in order to obtain the usual Bethe-Salpeter kernel. Finally they discuss the QCD case in the non-perturbative regime giving some insight in the nature of the interaction kernel.
