Abstract
It is discussed how various Ansätze for the dressed quark-photon (qqγ) vertices Γµ(q,q˘) influence the asymptotics of the γ*γ → π0 transition form factor. In this regard, we rectify certain misconceptions present in the literature.
Keywords
γ*γ → π0 transition; form factor; dressed quark-photon (qqγ) vertices
