BELLE Data on the ${\pi }^0\gamma \ast \gamma$ Form Factor: A Game Changer?

Abstract

We extend our analysis of the ${\pi }^0{\gamma }^{\ast }\gamma$ 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.
