We study the J/ψ→p¯ηp and J/ψ→p¯K+Λ reactions with a unitary chiral approach. We find that the unitary chiral approach, which generates the N∗(1535) dynamically, can describe the data reasonably well, particularly the ratio of the integrated cross sections. This study provides further support for the unitary chiral description of the N∗(1535). We also discuss some subtle differences between the coupling constants determined from the unitary chiral approach and those determined from phenomenological studies. |
