Pion radiative decays of excited hidden-charm pentaquark molecules: from molecules to the reported states
Yu-Jie Tang, Wen-Yan Peng, Rui Chen +1
The discovery of the hidden-charm pentaquarks \(P_c(4312)\), \(P_c(4440)\) and \(P_c(4457)\) by the LHCb collaboration are very likely to identify as the \(Σ_c^{(*)}\bar{D}^{(*)}\…

Exploring pion emission properties of (strange) hidden-charm molecular pentaquarks in a chiral quark model
Li-Cheng Sheng, Yu-Jie Tang, Yu-Xin Wan +2
The internal structure of the exotic and pentaquarks remains an open question. To address this, we demonstrate that pion emission serves as a sensitive probe by calc…
