Analysis of the vertexes *QQ*φ, *QQ*K*, Q**QK* and Q**Q with the light-cone QCD sum rules

Abstract

In this article, we parameterize the vertexes *QQ*φ, *QQ*K*, Q**QK* and Q**Q with four tensor structures due to Lorentz invariance, and study the corresponding four strong coupling constants with the light-cone QCD sum rules.
