Analysis of the vertexes ${\Omega }_Q^{\ast }{\Omega }_Q^{\ast }\varphi$, ${\Omega }_Q^{\ast }{\Xi }_Q^{\ast }{K}^{\ast }$, ${\Xi }_Q^{\ast }{\Sigma }_Q^{\ast }{K}^{\ast }$ and ${\Sigma }_Q^{\ast }{\Sigma }_Q^{\ast }\rho$ with the light-cone QCD sum rules

Abstract

In this article, we parameterize the vertexes ${\Omega }_Q^{\ast }{\Omega }_Q^{\ast }\varphi$, ${\Omega }_Q^{\ast }{\Xi }_Q^{\ast }{K}^{\ast }$, ${\Xi }_Q^{\ast }{\Sigma }_Q^{\ast }{K}^{\ast }$ and ${\Sigma }_Q^{\ast }{\Sigma }_Q^{\ast }\rho$ with four tensor structures due to Lorentz invariance, and study the corresponding four strong coupling constants with the light-cone QCD sum rules.
