Canonical interpretation of the X(4140) state within the $$^3P_0$$ 3P0 model
Abstract Recently, the LHCb Collaboration has confirmed the state X(4140), with a mass $$M=4146.5\pm 4.5^{+4.6}_{-2.8}$$ M=4146.5±4.5-2.8+4.6 MeV, and a much larger width $$\Gamma =83\pm 21^{+21}_{-14}$$ Γ=83±21-14+21 MeV than the previous experimental measurements, which has confused the understa...

| description | Abstract Recently, the LHCb Collaboration has confirmed the state X(4140), with a mass $$M=4146.5\pm 4.5^{+4.6}_{-2.8}$$ M=4146.5±4.5-2.8+4.6 MeV, and a much larger width $$\Gamma =83\pm 21^{+21}_{-14}$$ 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 $$\chi _{c1}(3P)$$ χc1(3P) interpretation for the X(4140), considering the mass spectra predicted in the quark model, and the strong decay properties within the $$^3P_0$$ 3P0 model. We also predict the strong decay properties of the charmonium states $$\chi _{c0}(3P)$$ χc0(3P) and $$\chi _{c2}(3P)$$ χc2(3P) . Our results show that the X(4140) state with the small width given in PDG can be explained as the charmonium state $$\chi _{c1}(3P)$$ χc1(3P) in the $$^3P_0$$ 3P0 model, and high precision measurement of the width of the X(4140) is crucial to understand its nature. |
