Canonical interpretation of the $X (4140)$ state within the $^{3} P_{0}$ model

Wei Hao, Guan-Ying Wang, En Wang +2

Recently, the LHCb Collaboration has confirmed the state $X (4140)$ , with a mass $M = 4146.5 \pm 4. 5_{- 2.8}^{+ 4.6}$ ~MeV, and a much larger width $Γ = 83 \pm 2 1_{- 14}^{+ 21}$ ~MeV than the pr…

The $ϕ (2170)$ production in the process $γ p \to η ϕp$

Chen-Guang Zhao, Guan-Ying Wang, Guan-Nan Li +2

We have studied the $γ p \to η ϕp$ reaction within the effective Lagrangian approach, by considering the contribution of the intermediate state $ϕ (2170)$ production, and the backgroun…

Triangle singularity in the $J / ψ \to K^{+} K^{-} f_{0} (980) (a_{0} (980))$ decays

Wei-Hong Liang, Hua-Xing Chen, Eulogio Oset +1

We study the $J / ψ \to K^{+} K^{-} f_{0} (980) (a_{0} (980))$ reaction and find that the mechanism to produce this decay develops a triangle singularity around $M_{\rm inv}(K^- f_0/K^-…

Analysis of the $e^{+} e^{-} \to J / ψD D ˉ$ reaction close to the threshold concerning claims of a $χ_{c 0} (2 P)$ state

En Wang, Wei-Hong Liang, Eulogio Oset

We analyze the $D D ˉ$ mass distribution from a recent Belle experiment on the $e^{+} e^{-} \to J / ψ D D ˉ$ reaction, and show that the mass distribution divided by phase space does…
