Schwinger-Dyson approach and generalized impulse approximation for the pi0 gamma^* gamma transition

High Energy Physics - Phenomenology 2011-04-15 v1

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 GeV^2, 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.
