Amongst the bound states produced by the strong interaction, radially excited meson and nucleon states offer an important phenomenological window into the long-range behavior of the coupling constant in Quantum Chromodynamics. We here report on some technical details related to the computation of the bound state’s eigenvalue spectrum in the framework of Bethe-Salpeter and Faddeev equations.
