Constraining the hidden-charm pentaquark predictions and discriminating the $P_{c} (4440)$ and $P_{c} (4457)$ spins through the effective range expansion

Fang-Zheng Peng, Li-Sheng Geng, Ju-Jun Xie

The Weinberg compositeness criterion dictates that a pure shallow bound state is characterized by a large scattering length $a_{0} ≫ O (1/ β)$ and a positive effective range…

Strong decays of $a_{0}$ , $f_{0}$ , $f_{2}$ , and $K_{2}^{*}$ resonances as dynamically generated states of two vector mesons

Qing-Hua Shen, Li-Sheng Geng, Ju-Jun Xie

The two-body strong decays of the $f_{0} (1500)$ , $f_{0} (1710)$ , $a_{0} (1710)$ , $f_{2} (1270)$ , $f_{2}^{'} (1525)$ , and $K_{2}^{*} (1430)$ resonances are investigated, assuming them as dynamically gene…

Identifying the two-pole structure of the $Λ (1405)$ using an SU(3) flavor filter

Ying-Bo He, Xiao-Hai Liu, Li-Sheng Geng +2

We propose a novel method to identify the two-pole structure of the $Λ (1405)$ . The two poles owe their origin to different quark flavor irreducible representations in the meson-bar…

The $Ω (2012)$ as a hadronic molecule

Ju-Jun Xie, Li-Sheng Geng

Recently, a new excited baryon state, $Ω (2012)$ , was observed in the invariant mass spectra of $K^{-} Ξ^{0}$ and $K_{S}^{0} Ξ^{-}$ by the Belle Collaboration. This state has a narrow width ($…

Theoretical study of $N (1535)$ and $Σ^{*} (1/ 2^{-})$ in the Cabibbo-favored process $Λ_{c}^{+} \to p K ˉ^{0} η$

Ying Li, Si-Wei Liu, En Wang +3

Motivated by the recent experimental measurements, we have investigated the Cabibbo-favored process $Λ_{c}^{+} \to p K ˉ^{0} η$ , where the $N (1535)$ resonance is dynamically generated…

Evidence of the low-lying baryon $Σ^{*} (1/ 2^{-})$ in the process $Λ_{c}^{+} \to η π^{+} Λ$

Wen-Tao Lyu, Sheng-Chao Zhang, Guan-Ying Wang +4

Motivated by the Belle measurements of the process $Λ_{c}^{+} \to η π^{+} Λ$ , we investigate this process by considering the contributions from the $Λ (1670)$ , $a_{0} (980)$ , and $Σ (1385)$ . In…
