论文摘要

在最近对新结构的观察$ x(4014)$的启发下,在$γγ\至γψ(2s)$的过程中,我们评估了分配$ x(4014)$作为$ d^\ ast \ ast \ bar {d}^\ ast $ ast $ molecular $ solecular chritage的可能性$ x(4014)$。 $ j/ψΩ$,$η_{c}η$和$η_{c}η^{\ prime} $通道的部分宽度被评估为$(0.41 \ sim 5.00)$,$($(2.05 \ sim7.49)$(0.11 \ sim7.49)$(0.11 \ sim0.51)。考虑到实验性观察和目前的估计,我们建议在Belle II中搜索$γγ\至J/ψΩ$过程中的$ x(4014)$。

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.
