Hidden-charm pentaquarks do not appear in J/ψ photoproduction because rescattering from ar{D}^{(*)}Σ_c intermediate states is suppressed relative to ar{D}^{(*)}Λ_c by a factor of roughly five in the relevant couplings.

Nonexistence of hidden-charm pentaquarks in $J/\psi$ photoproduction
Hidden-charm pentaquarks do not appear in J/ψ photoproduction because rescattering from ar{D}^{(*)}Σ_c intermediate states is suppressed relative to ar{D}^{(*)}Λ_c by a factor of roughly five in the relevant couplings.
