Analysis of the strong decay $X(4140)\to J/\psi \varphi$ via the light-cone QCD sum rules

Zun-Yan Di, Zhi-Gang Wang

In this article, we take the $X(4140)$ as the axialvector tetraquark state with the symbolic quark structure $[sc{]}_S[\bar{s}\bar{c}{]}_A+[sc{]}_A[\bar{s}\bar{c}{]}_S$, and calculate the…
