Role of the low-lying nucleon resonances in the $p\bar{p}\to \psi \eta$ reaction

Qin-Song Zhou, Jun-Zhang Wang, Ju-Jun Xie +1

Within the effective Lagrangian approach, we study the $p\bar{p}\to \psi \eta$ [$\psi \equiv \psi (3686)$, $J/\psi$] reaction at the low energy where the contributions from nucleon pole and…
