Analysis of the vertexes ${\Xi }_Q^{\ast }{\Xi }_Q^{\prime }V$, ${\Sigma }_Q^{\ast }{\Sigma }_{Q}V$ and radiative decays ${\Xi }_Q^{\ast }\to {\Xi }_Q^{\prime }\gamma$, ${\Sigma }_Q^{\ast }\to {\Sigma }_Q\gamma$

Abstract

In this article, we study the vertexes ${\Xi }_Q^{\ast }{\Xi }_Q^{\prime }V$ and ${\Sigma }_Q^{\ast }{\Sigma }_{Q}V$ with the light-cone QCD sum rules, then assume the vector meson dominance of the intermediate $\varphi (1020)$, $\rho (770)$ and $\omega (782)$, and calculate the radiative decays ${\Xi }_Q^{\ast }\to {\Xi }_Q^{\prime }\gamma$ and ${\Sigma }_Q^{\ast }\to {\Sigma }_Q\gamma$.
