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…

Light-cone sum rules analysis of the semi-leptonic $D_{s}^{+} \to f_{0} (980) (\to π^{+} π^{-}) e^{+} ν_{e}$ decay incorporating $f_{0} (980)$ mixing state twist-2 distribution amplitudes

Dan-Dan Hu, Xing-Gang Wu, Hai-Jiang Tian +2

The isospin-singlet scalar meson $f_{0} (980)$ is hypothesized to consist of two energy eigenstates, forming a mixture of $\frac{1}{2} (u ˉ u + d ˉ d)$ and $s ˉ s$ . Bui…

$η$ - $η^{'}$ mixing and its application in the $B^{+} / D^{+} / D_{s}^{+} \to η^{(')} ℓ^{+} ν_{ℓ}$ decays

Yu-Jie Zhang, Xing-Gang Wu, Dan-Dan Hu +1

In this paper, we take into account the intrinsic charm and gluonic contents into the $η - η^{'}$ mixing scheme and formulate the tetramixing $η - η^{'} - G - η_{c}$ to study the mixin…
