Imposing the SU(3) flavor eigenstate condition on udsc c-bar pentaquarks in a constituent quark model yields two structures matching the masses of P_cs(4338) and P_cs(4459) plus two additional predicted states below the J/ψΛ threshold.

Using effective Lagrangians under molecular assumptions for η_c D* and J/ψ D*, the authors estimate B_c production branching ratios of 10^{-4} and 10^{-5} respectively, with decay widths O(MeV).
