γ*γ→π([eta], [eta]) transition form factors
The surprising results by the BABAR Collaboration on the πγ transition form factor require new thoughts about the high-Q2 dependence of the form factors with virtual photons. We make use of the anomaly sum rule [J. Horejsi and O. Teryaev, Z. Phys. C 65, 691 (1995).] which relates the hadron spectral...
