Charge and Transition Form Factors of Light Mesons with Light-Front Quark Model

Abstract

The charge and transition form factors of pion ($F_\pi$, $F_{\pi\gamma}$, and $F_{\pi\gamma^*}$) are studied with the light-front quark model. We find that our results for $F_\pi$ and $F_{\pi\gamma}$ agree very well with experimental data. Furthermore, the decay constants of $\eta$ and $\eta'$ are evaluated. We also calculate $F_{\eta\gamma}$ and $F_{\eta'\gamma}$ and compare with the experimental data.
