Title: {gamma}*{gamma}*{yields}{pi}{sup 0} form factor from anti-de Sitter-space/QCD correspondence

Abstract

The recently measured {gamma}*{gamma}*{yields}{pi}{sup 0} anomalous form factor is analyzed using the D4/D8D8 holographic approach to QCD. The half-on-shell transition form factor is vector meson dominated and is shown to exactly tie to the charged-pion form factor. The holographic result compares well with the data for the lowest vector resonance.
