\begin{document}$J/\psi \phi$\end{document} scattering, heavy flavor hadrons, X(4160)"> \begin{document}$ J/\psi \phi $\end{document} invariant mass distribution in the \begin{document}$ e^+e^-\to \gamma J/\psi\phi $\end{document} reaction at a center-of-mass energy of \begin{document}$ \sqrt{s} = 4.6 $\end{document} GeV measured by the BESIII collaboration, which concluded that no significant signals were observed for \begin{document}$ e^+e^- \to \gamma X(4140) $\end{document} because of the low statistics. We show, however, that the \begin{document}$ J/\psi \phi $\end{document} invariant mass distribution is compatible with the existence of the \begin{document}$ X(4140) $\end{document} state, appearing as a peak, and a strong cusp structure at the \begin{document}$ D^*_s\bar{D}^*_s $\end{document} threshold, resulting from the molecular nature of the \begin{document}$ X(4160) $\end{document} state, which provides a substantial contribution to the reaction. This is consistent with our previous analysis of the \begin{document}$ B^+\to J/\psi\phi K^+ $\end{document} decay measured by the LHCb collaboration. We strongly suggest further measurements of this process with more statistics to clarify the nature of the \begin{document}$ X(4140) $\end{document} and \begin{document}$ X(4160) $\end{document} resonances."> The <i>X</i>(4140) and <i>X</i>(4160) resonances in the <inline-formula><tex-math id="Z-20190831131803">\begin{document}$ {{e^+e^-\to \gamma J/\psi \phi}}$\end{document}</tex-math><alternatives><graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="//www.macurncorp.com/cpc/article/app/id/f74bfd47-e086-494d-9b59-535f9902c9d6/CPC-2019-0222_Z-20190831131803.jpg"/><graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="//www.macurncorp.com/cpc/article/app/id/f74bfd47-e086-494d-9b59-535f9902c9d6/CPC-2019-0222_Z-20190831131803.png"/></alternatives></inline-formula> reaction -
