Abstract:

The status of exclusive two-body and three-body baryonic B decays is reviewed. The threshold enhancement effect in the dibaryon invariant mass and the angular distributions in the dibaryon rest frame are stressed and explained. Weak radiative baryonic B decays mediated by the electromagnetic penguin process

b\to s\gamma

are discussed. Puzzles with the correlation observed in

B^-\to p\bar pK^-

decay and the unexpectedly large rate observed for

B\to\Lambda_c\bar\Lambda_cK

are examined. The former may indicate that the

p\bar p

system is produced through some intermediate states, while the latter implies the failure of naive factorization for

\Lambda\bar\Lambda K

modes and may hint at the importance of final-state rescattering effects.
