| contents | The decay behavior of an exotic state can be used to probe its internal structure. We note that the hidden-charm pentaquark states, $P_ψ^{N}(4312)$, $P_ψ^{N}(4440)$, and $P_ψ^{N}(4457)$, have only been observed in the $J/ψp$ channel. In this work, we employ the effective Lagrangian approach to systematically investigate the two-body and three-body decays of the heavy quark spin symmetry multiplet of hadronic molecules $\bar{D}^{(*)}Σ_c^{(*)}$. Our results show that the partial decay widths of the hidden-charm pentaquark molecules into $\bar{D}^{(*)}Λ_c π$ are sizable so that $\bar{D}^{(*)}Λ_c π$ are promising channels to search for them, which can help clarify their molecular nature. |
