Abstract
In the framework of Dyson-Schwinger equations (DSE), we compute the transition form factor, . For the first time, in a continuum approach to quantun chromodynamics (QCD), it was possible to compute on the whole domain of space-like momenta. Our result agrees with CELLO, CLEO and Belle collaborations and, with the well-known asymptotic QCD limit, . Our analysis unifies this prediction with that of the pion's valence-quark parton distribution amplitude (PDA) and elastic electromagnetic form factor.
