  "abstract": "We study the decay \\(η_c\\to p\\bar{p}η\\) by combining the SU(3) flavor structure of the primary production with final-state interactions in the \\(pη\\) and \\(\\bar{p}η\\) subsystems, using the chiral unitary approach. The low-energy \\(S_{11}\\) dynamics, including the dynamically generated \\(N^*(1535)\\), is incorporated into the complete coupled-channel amplitude, and a phenomenological \\(N^*(1895)\\) contribution is included coherently. The \\(pη\\) and \\(\\bar{p}η\\) invariant-mass distributions are well described, and the \\(p\\bar{p}\\) distribution is predicted as a kinematic reflection of the \\(ηN\\) dynamics. The results support the dynamical interpretation of the \\(N^*(1535)\\) and suggest possible additional \\(S_{11}\\) strength near \\(1.9\\)~GeV.",
