hidden charm decays of $X(4014)$ in a $D^{\ast }{\bar{D}}^{\ast }$ molecule scenario

Abstract

Inspired by the recent observation of a new structure, $X(4014)$, in the process $\gamma \gamma \to \gamma \psi (2S)$, we evaluate the possibility of assigning $X(4014)$ as a $D^{\ast }{\bar{D}}^{\ast }$ molecular state with $I(J^{PC})=0(0^{++})$ by investigating the hidden charm decays of $X(4014)$. The partial widths of $J/\psi \omega$, ${\eta }_c\eta$ and ${\eta }_c{\eta }^{\prime }$ channels are evaluated to be about $(0.41\sim 5.00)$, $(2.05\sim 7.49)$ and $(0.11\sim 0.51)\mathrm{MeV}$, respectively. Considering the experimental observation and the present estimations, we proposed to search $X(4014)$ in the $\gamma \gamma \to J/\psi \omega$ process in Belle II.
