Abstract

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.
