Abstract
We study two-body baryonic decays of pseudoscalar B mesons to charmed-baryon-antibaryon pairs, where baryons (or antibaryons) are orbital ground states in spin doublets or quartets. The four-fermion interaction theory forbids F-wave decays for spin-quartet-quartet final-state configurations. SU(6) symmetry requires that all decay amplitudes are expressed by no more than eight parameters: three for S wave, four for P wave, and one for D wave. Both c inclusive and some exclusive branching ratios are studied based on the assumption of two-body dominance in baryonic decays of B mesons. Results are listed in tables. © 1990 The American Physical Society.
