The u-channel Lambda_c exchange enhances rescattering via Dbar(*) Sigma_c states in the piN to J/psiN reaction, producing clear peaks for Pc(4312) (1/2^-) and Pc(4457) (3/2^-) at microbarn cross sections while suppressing other states.

Belle and Belle II collaborations summarize new hadron spectroscopy measurements on bottomonium, charmonium, hidden-charm/strangeness pentaquarks, and baryons from combined data exceeding 1.5 ab^{-1}.
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.
