Abstract: The excitations of nucleon resonances with hidden charm, $N^*_{c\bar{c}}$, in the $\gamma p$ reactions are investigated by using the predictions from the available meson-baryons (MB) coupled-channel models. For the $\gamma\,p\rightarrow J/\psi\, p$ process, we first… read more here.

Abstract: 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… read more here.

DOI: 10.1103/physrevd.95.074031
Abstract: In this work, we investigate the possibility to interpret two nucleon resonances, the $N(1875)$ and the $N(2100)$ as hadronic molecular states from the $\Sigma^*K$ and $\Sigma K^*$ interactions, respectively. With the help of the effective… read more here.
