The dynamically generated $h_{1}$ state by the $K^{} K ˉ^{}$ interaction and its $K_{1} (1270) K ˉ$ and $b_{1} (1235) I ¨ $ decays

Qing-Hua Shen, Li-Sheng Geng, Xiang Liu +1

We investigate the dynamically generated $h_{1}$ state with spin-parity $J^{P} = 1^{+}$ and a mass around 1790~MeV, arising from the $K^{*} K ˉ^{*}$ interaction within the chiral unitary…

Study of $I ¨ _{c J} \to I^\cdot I^\cdot I^\cdot^{'}$ via intermediate charmed meson loop mechanisms and its implications for non-observation of $I^\cdot_{1} (1855)$ in $I ¨ _{c J}$ decays

Xin-Ru Wang, Shu-Qi Wang, Shi-Dong Liu +3

Recently, the BESIII Collaboration reported the first observation of the decays $I ¨ _{c J} \to I^\cdot I^\cdot I^\cdot^{'}$ in order to search for the $1^{-+}$ exotic state $I^\cdot_{1} (1855)$ . A partial…

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

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

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

Radiative decays of the $I^c ◯ (2012)$ as a hadronic molecule

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

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

Shedding light on the nature of $I ¨ (2170)$ state in the $e^{+} e^{-} \to I ¨ I ¨ ^{+} I ¨ ^{-}$ reaction

Xiang Wei, Qing-Hua Shen, Xiao-Hai Liu +1

We investigate the production of $I ¨ (2170)$ state in the $e^{+} e^{-} \to I ¨ I ¨ ^{+} I ¨ ^{-}$ reaction with the effective Lagrangian approach. In addition to the tree level contributions from t…

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 $a_{0} ≫ O (1/ I^^{2})$ and a positive effective range…
