Photon-meson transition form factors of light pseudoscalar mesons
The photon-meson transition form factors of light pseudoscalar mesons ${\ensuremath{\pi}}^{0}$, $\ensuremath{\eta}$, and ${\ensuremath{\eta}}^{\ensuremath{'}}$ 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 perturbative quantum chromodynamics approach at large ${Q}^{2}$. The calculated results …
