Radiative vertex $VP\gamma$ and $\eta -{\eta }^{\prime }$ mixing in light-cone sum rules

Jian-Mei Hou, Chang-Qiao Du, Hong Chen +1

In this work, we calculate radiative vertex $VP\gamma$ ($V=\varphi ,\omega ,\rho$ and $P=\eta ,{\eta }^{\prime }$) by utilizing $\omega -\varphi$ mixing scheme and taking into account the contributions of the three-particle twist-4…
