The resonances $X (4140)$ , $X (4160)$ , and $P_{cs} (4459)$ in the decay of $Λ_{b} \to J / ψ Λ ϕ$

Wen-Ying Liu, Wei Hao, Guan-Ying Wang +3

We study the decay of $Λ_{b} \to J / ψ Λ ϕ$ by taking into account the intermediate resonances $X (4140)$ , $X (4160)$ , and $P_{cs} (4459)$ . In addition to the peak of the $X (4140)$ , we also…

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

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

Recently, LHCb collaboration has confirmed the state $X (4140)$ , with a much larger width $Γ = 83 \pm 2 1_{- 14}^{+ 21}$ MeV than the previous experimental measurements, which has confus…

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

Guan-Ying Wang, Chen-Guang Zhao, En Wang +2

We have studied the $γ p \to η ϕp$ reaction within the effective Lagrangian approach, and our results show that there may be a peak, at least a bump structure around 2180 MeV associat…

Role of scalar $a_{0} (980)$ in the single Cabibbo Suppressed process $D^{+} \to π^{+} π^{0} η$

Man-Yu Duan, Jun-Ya Wang, Guan-Ying Wang +2

Taking into account that the scalar $a_{0} (980)$ can be dynamically generated from the pseudoscalar-pseudoscalar interaction within the chiral unitary approach, we have studied the s…

Enhancement near the $p ˉ Λ$ threshold in the $χ_{c 0} \to p ˉ K^{+} Λ$ reaction

Guan-Ying Wang, Man-Yu Duan, En Wang +1

We have analyzed the reaction $χ_{c 0} \to p ˉ K^{+} Λ$ reported by the BESIII Collaboration, taking into account the contributions from the intermediate $K (1830)$ , $N (2300)$ , and $…

Signatures of the two $K_{1} (1270)$ poles in $D^{+} \to ν e^{+} V P$ decay

Guan-Ying Wang, Luis Roca, En Wang +2

We analyze theoretically the $D^{+} \to ν e^{+} ρ K ˉ$ and $D^{+} \to ν e^{+} K ˉ^{*} π$ decays to see the feasibility to check the double pole nature of the axial-vector resonance $K_1(127…
