Regge behaviour within the Bethe-Salpeter approach

We present a calculation of the spectrum of light and heavy quark bound states in the rainbow-ladder truncation of Dyson-Schwinger/Bethe-Salpeter equations. By extending the formalism include the case of total angular momentum J = 3, we are able to explore Regge trajectories and make prediction of tensor bound states for light and heavy quarkonia.
