Abstract

The applications of the consistently coupled Schwinger-Dyson and Bethe-Salpeter approach to the \ensuremathη\ensuremath-\ensuremathη^\ensuremath' complex are extended to the two-photon transition form factors of \ensuremathη and \ensuremathη^\ensuremath' for spacelike transferred momenta. We compare our predictions with experiment and some other theoretical approaches.
