Hidden Charm Decays of $Y(4626)$ in a $D_s^{\ast +}{D}_{s1}(2536{)}^{-}$ Molecular Frame

In this work, we investigate the hidden charm decays properties of $Y(4626)$, where $Y(4626)$ is assigned as a $S-$wave $D_s^{\ast +}{D}_{s1}(2536{)}^{-}$ molecular state with $J^{PC}=1^{--}$. The partial widths of the processes $Y(4626)\to J\mathrm{/}\psi \eta$, $J\mathrm{/}\psi {\eta }^{\mathrm{\prime }}$, ${\eta }_c\phi$, and ${\chi }_{cJ}\phi ,(J=\{0,1,2\})$ are estimated by employing the effective Lagrangian approach. The present estimations indicate that the partial widths of the $J\mathrm{/}\psi \eta$ and $J\mathrm{/}\psi {\eta }^{\mathrm{\prime }}$ channels are of the order of 1 MeV, while the one of ${\chi }_{c1}\phi$ is of the order of 0.1 MeV. Thus, we propose to further examine the molecular interpretation of $Y(4626)$ by searching it in the cross sections for the $e^{+}{e}^{-}\to J\mathrm{/}\psi {\eta }^{(\mathrm{\prime })}$ processes, which should be accessible by the BES III and Belle II.
