Branching fraction of Ξ b c + → Ξ c + J / ψ in the final-state-interaction approach
Abstract
The process of Ξ b c + → Ξ c + J / ψ is among the most favored modes for searching for bottom-charm baryons. However, its branching fraction has never been studied in theory. In this work, we investigate the branching fraction of Ξ b c + → Ξ c + J / ψ in the final-state-interaction approach, as it is dominated by the color-suppressed nonfactorizable contributions. A similar process, Λ b 0 → Λ 0 J / ψ , is used as a control mode to fix the model parameter. Consequently, the branching fraction of Ξ b c + → Ξ c + J / ψ is predicted to be ( 1.5 5 − 0.42 + 0.50 ) × 10 − 4 . With the production rate of bottom-charm baryons and the detection efficiencies of the final states, it is expected for considerable signal events to observe Ξ b c + in the near future.
