- Title
An Assessment of Pseudoscalar and Vector Meson Electromagnetic Form Factors.

- Abstract
Within the framework of the Dyson-Schwinger/Bethe-Salpeter equations of quantum chromodynamics, we investigate the electromagnetic form factors of pseudoscalar and vector mesons with different hidden-flavor, from light to heavy quark sectors, and compare the results with those of the single-pole vector meson dominance (VMD) model. It is found that the charge radius of vector meson is larger than that of its pseudoscalar counterpart. As the current-quark mass increases, the electric form factor of the vector meson tends to approach that of its pseudoscalar counterpart, and gradually deviates from the prediction of the VMD model.
