The heavy flavor conserving hadronic weak decay of the ground-state bottom baryons

In this work, the heavy-flavor-conserving (HFC) hadronic weak decays of bottom baryons are studied in the framework of the nonrelativistic constituent quark model (NRCQM). We show that the pole terms play an indispensable role in the description of the branching ratio of Ξ_b^- → Λ_b⁰π^-. With the pole terms included, we can make reliable predictions for Ξ_b⁰ → Λ_b⁰π⁰. A combined study of the HFC hadronic weak decays allows us to make a reasonable prediction for Ω_b^- → Ξ_b^-(0)π^0(-), which can be searched for at the LHCb and Belle-II experiments.
