The strong coupling $g_{XJ/\psi \varphi }$ of $X(4700)\to J/\psi \varphi$ in the light-cone sum rules

Yiling Xie, Dazhuang He, Xuan Luo +1

We assign the scalar tetraquark and the D-wave tetraquark state for $X(4700)$ and calculate the width of the decay $X(4700)$ $\to J/\psi \varphi$ within the framework of light-cone sum rules…
