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/physrevd.101.034018
Abstract: We calculate the effective potentials of the ΞcD¯(*), Ξc′D¯(*), and Ξc*D¯(*) system s with the chiral effective field theory up to the next-to-leading order. We simultaneously consider the short-, intermediate-, and long-range interactions. With the… read more here.

DOI: 10.3390/universe9060265
Abstract: Inspired by the LHCb observation of hidden-charm pentaquarks, i.e., Pc(4312), Pc(4440), and Pc(4457) in the J/ψp invariant mass spectrum, a calculation of the J/ψp scattering cross-section was performed using the quark-delocalization color screening model. The… read more here.
