Universal behavior of the [Formula: see text] transition form factors
The photon transition form factors of π, η and [Formula: see text] are discussed in view of recent measurements. It is shown that the exact axial anomaly sum rule allows a precise comparison of all three form factors at high- [Formula: see text] independent of the different structures and distributi...
