DOI: 10.1103/physrevc.100.035206
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.

DOI: 10.1103/physrevc.97.024307
Abstract: In coupled-channel models the poles of the scattering S-matrix are located on different Riemann sheets. Physical observables are affected mainly by poles closest to the physical region but sometimes shadow poles have considerable effect, too.… read more here.

Abstract: The $\alpha$ inelastic scattering on $^{16}$O is investigated with the coupled-channel calculation using the $\alpha$-nucleus coupled-channel potentials, which are microscopically derived by folding the the Melbourne $g$-matrix $NN$ interaction with the $^{16}$O and $\alpha$ densities.… read more here.

DOI: 10.1103/physrevd.104.074025
Abstract: We apply the diabatic framework, a QCD-based formalism for the unified study of quarkoniumlike systems in terms of heavy quark-antiquark and open-flavor meson-meson components, to the description of coupled-channel meson-meson scattering. For this purpose, we… read more here.

DOI: 10.1103/physrevd.104.114001
Abstract: The f0(1710) was previously proposed to be dynamically generated state by interactions between vector mesons. We extend the study of f0(1710) by including its coupling to channels of pseudoscalar mesons within coupled-channel approach. The channels… read more here.

Abstract: We study the excited $B$ mesons' contributions to the coupled-channel effects under the framework of ${}^3P_0$ model for the bottomonium. Contrary to what has been widely accepted, the contributions of $P$ wave $B$ mesons are… read more here.
