Belle data on the π0γ*γ form factor: A game changer?
Abstract
We extend our analysis [S. S. Agaev, V. M. Braun, N. Offen, and F. A. Porker, Phys. Rev. D 83, 054020 (2011)] of the π0γ*γ form factor by including a comparison with the new Belle data [S. Uehara (Belle Collaboration), arXiv:1205.3249]. The necessity of new precision measurements in a broad interval of momentum transfers is emphasized.
