ResumoWe describe the ϱ meson and Δ baryon in a coupled-channel formalism in which these hadrons are bound quark states in a closed channel and hadron scattering states in an open channel. We obtain good agreement with the known properties of the ϱ and Δ. Furthermore, we find that the coupling between channels produces substantial shifts in the calculated masses of the ϱ and Δ.
