"gamma^* gamma -> eta, eta' transition form factors in Schwinger-Dyson approach", invited talk at ECT* Collaboration Meeting on Dynamical Aspects of the QCD Phase Transition, Trento, Italy, 12-15 March 2001.

The bound-state Schwinger-Dyson and Bethe-Salpeter (SD-BS) approach is chirally well-behaved and provides a reliable treatment of the eta-eta' complex although a ladder approximation is employed. Two-photon processes are described well both for off shell photons and in the on-shell limit.
