A Bethe-Salpeter-Equation study with the (A^2)-enhanced effective QCD coupling
Dyson-Schwinger equations provide an effective approach to physics of strong interactions. To reproduce the hadronic phenomenology well, the Dyson-Schwinger approach in the rainbow-ladder approximation must employ an effective interaction between quarks which is fairly strong at intermediate (Q^2 - 0.5 GeV^2) spacelike transferred momenta.
