Four-body baryonic decays of $B\to p\bar{p}{\pi }^{+}{\pi }^{-}({\pi }^{+}{K}^{-})$ and $\Lambda \bar{p}{\pi }^{+}{\pi }^{-}(K^{+}{K}^{-})$

Abstract

We study the four-body baryonic $B\to {\mathbf{B}}_1{\bar{\mathbf{B}}}_2{M}_1{M}_2$ decays with ${\mathbf{B}}_{1,2}$ ($M_{1,2}$) being charmless baryons (mesons). In accordance with the recent LHCb observations, each decay is considered to proceed through the $B\to M_1{M}_2$ transition together with the production of a baryon pair. We obtain that $\mathcal{B}(B^{-}\to \Lambda \bar{p}{\pi }^{+}{\pi }^{-})=(3.7_{-1.0}^{+1.5})\times 10^{-6}$ and $\mathcal{B}({\bar{B}}^0\to p\bar{p}{\pi }^{+}{\pi }^{-},p\bar{p}{\pi }^{+}{K}^{-})=(3.0\pm 0.9,6.6\pm 2.4)\times 10^{-6}$, in agreement with the data. We also predict $\mathcal{B}(B^{-}\to \Lambda \bar{p}{K}^{+}{K}^{-})=(3.0_{-0.9}^{+1.3})\times 10^{-6}$, which is accessible to the LHCb and BELLE experiments.
