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

Abstract

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