$^3P_0$模型中$X(4140)$状态的规范解释
Canonical interpretation of the $X(4140)$ state within the $^3P_0$ model
摘要：
最近，LHCb合作已经确认了状态$X(4140)$，具有比以前的实验测量大得多的宽度$Γ= 83\pm 21^{+21}_{-14}$ MeV，这混淆了对其性质的理解。我们研究了$X(4140)$的$χ_{c1}(3P)$解释的可能性，考虑到质量和强衰变性质。
英文摘要：
Recently, LHCb collaboration has confirmed the state $X(4140)$, with a much larger width $Γ= 83\pm 21^{+21}_{-14}$ MeV than the previous experimental measurements, which has confused the understanding of its nature. We have investigated the possibility of the $χ_{c1}(3P)$ interpretation for the $X(4140)$, considering the mass and the strong decay properties.
