Charge and Transition Form Factors of Light Mesons with Light-Front Quark Model
Abstract
Description
The charge and transition form factors of pion ($F_π$, $F_{πγ}$, and $F_{πγ^*}$) are studied with the light-front quark model. We find that our results for $F_π$ and $F_{πγ}$ agree very well with experimental data. Furthermore, the decay constants of $η$ and $η'$ are evaluated. We also calculate $F_{ηγ}$ and $F_{η'γ}$ and compare with the experimental data.
