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

29 May 2020 Zhou Qin-Song Wang Jun-Zhang Xie Ju-Jun Liu Xiang

Within the effective Lagrangian approach, we study the $p\bar{p} \rightarrow \psi\eta$ [$\psi\equiv\psi(3686)$, $J/\psi$] reaction at the low energy where the contributions from nucleon pole and low-lying nucleon resonances, $N(1520)$, $N(1535)$ and $N(1650)$ are considered. All the model parameters are determined with the help of current experimental data on the decay of $\psi \to p \bar{p} \eta$... (read more)
