We investigate the light-quarkonium spectrum using a covariant Dyson–Schwinger–Bethe–Salpeter-equation approach to QCD. We discuss splittings among as well as orbital angular momentum properties of various states in detail and analyze common features of mass splittings with regard to properties of the effective interaction. In particular, we predict the mass of $$\bar{s}s$$s¯s exotic $$1^{-+}$$1-+ states, and identify orbital angular momentum content in the excitations of the $$\rho $$ρ meson…
