Abstract
- Recently, the LHCb Collaboration has confirmed the state X(4140), with a mass M = 4146.5 ± 4. 5 - 2.8 + 4.6 MeV, and a much larger width Γ = 83 ± 21 - 14 + 21 MeV than the previous experimental measurements, which has confused the understanding of its nature. We will investigate the possibility of the χ c 1 (3 P) interpretation for the X(4140), considering the mass spectra predicted in the quark model, and the strong decay properties within the 3 P 0 model. We also predict the strong decay properties of the charmonium states χ c 0 (3 P) and χ c 2 (3 P) . Our results show that the X(4140) state with the small width given in PDG can be explained as the charmonium state χ c 1 (3 P) in the 3 P 0 model, and high precision measurement of the width of the X(4140) is crucial to understand its nature.
