Abstract

We review the pion-photon transition form factor calculated in the Schwinger-Dyson approach and an impulse approximation. We present results for it far above the scales presently accessible for measurement, up to 36 GeV2, and demonstrate agreement with the analytically inferred asymptotic behavior, for which we also provide a new derivation. We discuss how measurements at Jefferson Lab can provide information on how quarks are dynamically dressed.
