Probing the $γ γ^{*} \to η^{(')}$ Transition Form Factors with Newly Derived $η^{(')}$ -Meson Light-Cone Distribution Amplitudes

Dan-Dan Hu, Xing-Gang Wu, Yu-Jie Zhang +2

In the present work, we analyze the properties of the transition form factors (TFFs) for the $γ γ^{*} \to η^{(')}$ process, employing the $η^{(')}$ -meson light-cone distribut…
