We perform a general SU(3)F analysis of b→ cc¯ s(d) decays of members of the beauty baryon antitriplet to a member of the light baryon octet and a singlet. Under several reasonable assumptions we found |A(Ξb0→ΛS)/A(Ξb0→Ξ0S)|≈1/6|Vcb∗Vcd/(Vcb∗Vcs)| and | A(Λ b→ Σ S) / A(Λ b→ Λ S) | ∼ 0.02 . These two relations have been recently probed by LHCb for the case of S = J/ψ. The former agrees with the measurement, while for the latter our prediction lies close to the upper bound set by LHCb.
