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

Abstract

Inspired by the recent observation of a new structure, $X(4014)$, in the process $γγ\to γψ(2S)$, 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 $J/ψω$, $ η_{c}η$ and $η_{c}η^{\prime}$ channels are evaluated to be about $(0.41\sim 5.00)$, $(2.05\sim7.49)$ and $(0.11\sim0.51)\ \mathrm{MeV}$, respectively. Considering the experimental observation and the present estimations, we proposed to search $X(4014)$ in the $γγ\to J/ψω$ process in Belle II.
