A dressed quark propagator representation in the Bethe–Salpeter description of mesons
Abstract:Using a non-perturbative approach that involves the Dyson–Schwinger equations of QCD and an effective interaction within their rainbow-ladder truncation scheme, we explore the effectiveness of a parametrization of dressed quark propagators in studying meson properties. The propagator parametrization is also used to extract useful information about a possible constituent-like behavior of the dynamical solution in the heavy quark mass limit and the effect on physical observables. Other benefits of this approach are also discussed and analyzed.
