Baryonic B Meson Decays

We review the two- and three-body baryonic B decays with the dibaryon (BB '& nbsp;over bar ) as the final states. Accordingly, we summarize the experimental data of the branching fractions, angular asymmetries, and CP asymmetries. Using the W-boson annihilation (exchange) mechanism, the branching fractions of B ? BB '& nbsp;& nbsp;over bar are shown to be interpretable. In the approach of perturbative QCD counting rules, we study the three-body decay channels. In particular, we review the CP asymmetries of B ? BB '& nbsp;over bar M, which are promising to be measured by the LHCb and Belle II experiments. Finally, we remark the theoretical challenges in interpreting B(B & nbsp;? pp & nbsp;over bar rho(-& nbsp;))& nbsp;and B(B ? pp over bar mu(-)& nbsp;nu over bar( mu).
