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…

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…

Triangle singularity in the $J / ψ \to γ p ˉ Δ$ decay

Ke Wang, Rong Li, Bo-Chao Liu

In this work, we study the role of triangle singularity in the $J / ψ \to γ p ˉ Δ$ decay. We find that through a triangle mechanism, involving a triangle loop composed by $ω$ , $π$ …

Studying triangle singularity through spin observables

Ke Wang, Shao-Fei Chen, Bo-Chao Liu

In this work, we study the spin density matrix element $ρ_{00}$ of the $ϕ$ in the decay $J / ψ \to η π ϕ$ . In previous studies, a band around 1.4 GeV on the $π^{0} ϕ$ distribution…
