Information on B decays with baryons in the final states is rather scarce. As such, a search for the two-body baryonic B decays by Belle showed that their relative probabilities are rather small. Moreover, the observation of the decays with branchin fractions considerably higher than expected indicates that color-suppressed B decays with baryons in the final state are likely to be sizable. This motivated a search for the color-suppressed decays B̄0 → D(*)0 pp̄.
