Here, we add the resonant γp → N*_c¯c → J/ψp amplitudes to examine the effects of N*_c¯c excitations on the cross sections of γp→J/ψp in the near threshold energy region covered by the recent experiments at Jefferson Lab. The N*_c¯c → MB transition matrix elements are determined from the partial decay widths predicted by the considered meson-baryon coupled-channel models of N*_c¯c.
