Nucleon resonances in πN→η'N and J/ψ→pη'

We are aiming to study the J/Ψ→Pη' decay in an isobar model and the effective Lagrangian approach on the basis of the coupling constants extracted from the πN→η'N reaction.After a careful exploration of the contributions of the S_(11)(1535),P_(11)(1710),P_(13)(1900),S_(11)(2090) and P_(11)(2100) resonances,we conclude that either a subthreshold resonance or a broad P-wave state in the near threshold range seems to be indispensable to describe the present data of the πN→η'N.Furthermore,at least one broad resonance above η'N threshold is preferred.With this detailed analysis,we give the invariant mass spectrum and Dalitz plot of the J/Ψ→Pη' decay for the purpose of assisting the future detailed partial wave analysis.It is found that the J/Ψ→Pη' data are useful for disentangling the above or below threshold resonant contribution,though it still further needs the differential cross section data ofπN→η'N to realize some of the resonant and non-resonant contribution.
