摘要：

We study the four-body baryonic B -> B1B2M1M2 decays with B-1,B-2 (M-1,M-2) being charmless baryons (mesons). In accordance with the recent LHCb observations, each decay is considered to proceed through the B -> M1M2 transition together with the production of a baryon pair. We obtain that B (B- -> Lambda(p) over bar pi(+)pi(-)) = (3.7(-1.0)(+1.5)) x 10(-6) and B((B) over bar (0) -> p (p) over bar pi(+)pi(-), p (p) over bar pi K-+(-)) = (3.0 +/- 0.9, 6.6 +/- 2.4) x 10-6, in agreement with the data. We also predict B(B- -> Lambda(p) over barK(+)K(-)) = (3.0(-0.9)(+1.3)) x 10(-6), which is accessible to the LHCb and BELLE experiments. (C) 2017 The Author(s). Published by Elsevier B.V.
