Description
The analytic structure of two-body bound state amplitudes is embedded in the Nakanishi integral representation in terms of real functions. Within the rainbow-ladder truncation, we derive the integral equations for these Nakanishi spectral functions from the corresponding Bethe-Salpeter equations in Minkowski space. The resulting integral equations are then solved numerically using adaptive mesh grids with solutions verified in Euclidean space.
