The dynamically generated $N (1535)$ state in the $Λ_{c}^{+} \to p K ˉ^{0} π^{0}$ decay

Ying Li, En Wang, Li-Sheng Geng +1

We present a theoretical analysis of the process $Λ_{c}^{+} \to p K ˉ^{0} π^{0}$ within the chiral unitary approach, with particular emphasis on the dynamically generated $N (1535)$ reso…

Radiative decays of the $Ω (2012)$ as a hadronic molecule

Qing-Hua Shen, Jun-Xu Lu, Li-Sheng Geng +2

We present a theoretical investigation of the radiative decay process $Ω (2012) \to γ Ω$ , where the $Ω (2012)$ resonance with spin-parity $J^{P} = \frac{3}{2}^{-}$ , is treated as a dynamica…

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…
