Exploring $K Ξ^{}$ and $K^{} Ξ$ molecular states and the triangle singularity in the $K^{-} p \to K Ξ (1530)$ reaction

Ke Wang, Fei Huang, Bing-Song Zou

We investigate the $K^{-} p \to K Ξ (1530)$ reaction within an effective Lagrangian approach, exploring possible $K Ξ^{*}$ and $K^{*} Ξ$ hadronic molecular states and the role of the tria…

Sifting out the neutral and charged components of $X (3872)$ from a spin observable

Ke Wang, Yu-Fei Wang, Bo-Chao Liu +1

In this work, we propose a new method to detect the composition of the $X (3872)$ state. Based on a widely accepted interpretation that $X (3872)$ is a weakly bound $S$ -wave molecule…

Effects of hadronic molecule $N (2080) 3/ 2^{-}$ on $K^{*+} Λ$ photoproduction

Wen-Ya Tian, Neng-Chang Wei, Yu-Fei Wang +2

In our previous work [Phys. Rev. C {\bf 101}, 014003 (2020)], we have analyzed all available data on differential cross sections and spin density matrix elements for the $γp \to K^…

Nature of the $P_{c}$ states from compositeness criteria

Yu-Fei Wang, Chao-Wei Shen, Deborah Rönchen +3

Based on a coupled-channel approach, we investigate the structures of four $P_{c}$ states through compositeness criteria. Toward a more precise description of the states, we have obt…

Search for the $Σ (1380) 1/ 2^{-}$ state in $Λ_{c}^{+} \to γ π^{+} Λ$ decay by triangle singularity

Ke Wang, Yu-Fei Wang, Bo-Chao Liu +1

In this work, we investigate the resonance production in $Λ_{c}^{+} \to γ π^{+} Λ$ decay through the triangle singularity (TS) mechanism, within an effective Lagrangian approach. We find…
