Abstract

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 D^(*)Σ_c^(*). Our results show that the partial decay widths of the hidden-charm pentaquark molecules into D^(*)Λ_c π are sizable so that D^(*)Λ_c π are promising channels to search for them, which can help clarify their molecular nature.
