We propose that the $X\left(3915\right)$ observed in the $J/\psi \omega$ channel is the same state as the ${\chi }_{c2}\left(3930\right)$, and the $X\left(3960\right)$, observed in the $D_s^{+}{D}_s^{-}$ channel, is an S-wave $D_s^{+}{D}_s^{-}$ hadronic molecule. In addition, the $J^{\mathit{PC}}=0^{++}$ component in the $B^{+}\to D^{+}{D}^{-}{K}^{+}$ assigned to the $X\left(3915\right)$ in the current Review of Particle Physics has the same origin as the $X\left(3960\right)$, which has a mass around 3.94 GeV. To check the proposal, the available data in the $D\overline{D}$ and $D_s^{+}{D}_s^{-}$ channels from both B decays and $\gamma \gamma$ fusion reaction are analyzed considering both the $D\overline{D}\text{-}{D}_s{\overline{D}}_s\text{-}{D}^{*}{\overline{D}}^{*}\text{-}{D}_s^{*}{\overline{D}}_s^{*}$ coupled channels with $0^{++}$ and a $2^{++}$ state introduced additionally. It is found that all the data in different processes can be simultaneously well reproduced, and the coupled-channel dynamics produce four hidden-charm scalar molecular states with masses around 3.73, 3.94, 3.99 and 4.23 GeV, respectively. The results may deepen our understanding of the spectrum of charmonia as well as of the interactions between charmed hadrons.

我们建议$X\left(3915\right)$观察到$杰/\psi \omega$通道与状态相同${\chi }_{C\mathrm{2个}}\left(3930\right)$, 和$X\left(3960\right)$, 在中观察到${丁}_{秒}^{+}{丁}_{秒}^{-}$通道，是S波${丁}_{秒}^{+}{丁}_{秒}^{-}$强子分子。除此之外${杰}^{\mathit{个人电脑}}=0^{++}$中的组件${乙}^{+}\to {丁}^{+}{丁}^{-}{钾}^{+}$分配给$X\left(3915\right)$在当前的粒子物理学评论中与$X\left(3960\right)$，其质量约为 3.94 GeV。要检查提案，可用数据在$丁\overline{丁}$和${丁}_{秒}^{+}{丁}_{秒}^{-}$来自B衰减和$\gamma \gamma$聚变反应进行了分析，同时考虑到$丁\overline{丁}\text{-}{丁}_{秒}{\overline{丁}}_{秒}\text{-}{丁}^{*}{\overline{丁}}^{*}\text{-}{丁}_{秒}^{*}{\overline{丁}}_{秒}^{*}$耦合通道与$0^{++}$和一个${\mathrm{2个}}^{++}$状态另外介绍。发现不同过程中的所有数据都可以同时很好地再现，耦合通道动力学产生四个隐藏的魅力标量分子态，质量分别约为 3.73、3.94、3.99 和 4.23 GeV。结果可能会加深我们对 charmonia 光谱以及迷人强子之间相互作用的理解。
