Abstract: Recently, LHCb collaboration has confirmed the state $X(4140)$, with a much larger width $\Gamma= 83\pm 21^{+21}_{-14}$ MeV than the previous experimental measurements, which has confused the understanding of its nature. We have investigated the possibility of the $\chi_{c1}(3P)$ interpretation for the $X(4140)$, considering the mass and the strong decay properties.<br />Comment: 4 pages, 1 figure, 1 table, contribution to 18th International Conference on Hadron Spectroscopy and Structure (HADRON 2019)
