  "abstract": "The LHCb Collaboration has recently reported the first observation of the decay $${\\bar{B}}_s^0\\rightarrow \\Lambda _c^+\\bar{\\Lambda }_c^-$$ B ¯ s 0 → Λ c + Λ ¯ c - , along with measurements of the branching fractions for both $${\\bar{B}}^0\\rightarrow \\Lambda _c^+\\bar{\\Lambda }_c^-$$ B ¯ 0 → Λ c + Λ ¯ c - and $${\\bar{B}}_s^0\\rightarrow \\Lambda _c^+\\bar{\\Lambda }_c^-$$ B ¯ s 0 → Λ c + Λ ¯ c - . In this work, we investigate these two decays within the framework of final state re-scattering. Our results show that the predicted branching fractions are consistent with the experimental measurements, which indicates the significant role of long-distance final-state interactions in such baryonic B decays. Furthermore, we present predictions for the direct CP asymmetries and the asymmetry parameters. Numerically, both decays exhibit nearly vanishing direct CP asymmetries and suppressed longitudinal polarizations $$\\alpha $$ α , whereas the sizable values of $$\\beta $$ β and $$\\gamma $$ γ reflect strong interference between the two helicity amplitudes and provide sensitive probes of the decay dynamics.",
