Query: Soft QCD Modeling of Meson Electromagnetic Form Factors   We summarize recent progress in soft QCD modeling based on the set of
Dyson--Schwinger equations truncated to ladder-rainbow level. We pay particular
attention to electromagnetic elastic and transition form factors of the pion.
This covariant approach accommodates quark confinement and implements the QCD
one-loop renormalization group behavior. The dressed quark propagators are
compared to the most recent lattice-QCD data.
