Description
In the framework of Schwinger-Dyson Equations, we calculate the (neutral) Pion-to-two-photons transition form factor. This problem involves quantitatively careful parameterization of the quark propagator and the pion Bethe-Salpeter amplitudes in order to be able to numerically access large space-like momenta of the probing photons. Also, in order to be consistent with the so-called chiral anomaly, G(0)=1/2, and the low momentum experimental data, one must model a consistent quark-photon vertex. Our results are relevant for the experiments carried out at BaBar and Belle, and future experiments of Belle II.
