Analysis of the vertexes ${\mathrm{\Omega }}_Q^{\ast }{\mathrm{\Omega }}_Q\varphi$ and radiative decays ${\mathrm{\Omega }}_Q^{\ast }\to {\mathrm{\Omega }}_Q\gamma$

In this article, we study the vertexes ${\mathrm{\Omega }}_Q^{\ast }{\mathrm{\Omega }}_Q\varphi$ with the light-cone QCD sum rules, then assume the vector meson dominance of the intermediate $\varphi (1020)$, and calculate the radiative decays $\Omega_Q^*\to \Omega_Q \gamma$.
