Photon-meson transition form factors of light pseudoscalar mesons

Abstract

The photon-meson transition form factors of light pseudoscalar mesons ${\pi }^0$, $\eta$, and ${\eta }^{\prime }$ are systematically calculated in a light-cone framework, which is applicable as a light-cone quark model at low $Q^2$ and is also physically in accordance with the light-cone pQCD approach at large $Q^2$. The calculated results agree with the available experimental data at high energy scale. We also predict the low $Q^2$ behaviors of the photon-meson transition form factors of ${\pi }^0$, $\eta$ and ${\eta }^{\prime }$, which are measurable in $e+A(Nucleus)\to e+A+M$ process via Primakoff effect at JLab and DESY.
