Universal behaviour of the $γ^{*} γ \to (π^{0}, η, η^{'})$ transition form factors

Dmitri Melikhov, Berthold Stech

The photon transition form factors of $π$ , $η$ and $η^{'}$ are discussed in view of recent measurements. It is shown that the exact axial anomaly sum rule allows a precise comparison…

On the $γ^{*} γ \to π (η, η^{'})$ transition form factors

Dmitri Melikhov, Berthold Stech

The surprising results by the BarBar collaboration on the $π γ$ transition form factor require new thoughts about the high- $Q^{2}$ dependence of the form factors with virtual photons.…
