Abstract
Within the Dyson-Schwinger-equation approach to modeling QCD for meson physics, we present new results for gρππ and the coupling constants and form factors for the transitions γ ∗πρ and γ ∗π 0γ. We discuss the role of the sub-dominant covariants of the π Bethe-Salpeter amplitude and investigate the asymptotic behavior of the γ ∗π 0γ form factor.
Keywords
