BELLE Data on the $π^0 γ* γ$ Form Factor: A Game Changer?    [PDF]

S. S. Agaev, V. M. Braun, N. Offen, F. A. Porkert

We extend our analysis of the $\pi^0\gamma^*\gamma$ form factor by including a comparison with the new BELLE data. The necessity of new precision measurements in a broad interval of momentum transfers is emphasized.
