Within the Dyson-Schwinger equation approach to modeling QCD for meson physics, we present new results for g_rpp and the coupling constants and form factors for the transitions g^* pr and g^* p⁰ g. We discuss the role of the sub-dominant covariants of the p Bethe-Salpeter amplitude and investigate the asymptotic behavior of the g^* p⁰ g form factor.
