Abstract: (Elsevier)

A detailed description is presented of the method used and the results obtained for measuring various decay widths of the B-mesons into baryon-antibaryon pairs: (i) into two light baryons: B → p p , Δ p , … , (ii) into one light and one charmed baryon: B → p Σ c , p Λ c ,… , (iii) into two charmed baryons: B → Σ c , Ξ c , Λ c Ξ c ,… , (iv) the decays induced by the b → s and b → d penguin contributions: B → p Σ, p Λ, Δ Σ,… . As a by-product, we present the result for the B-meson decay constant, f B , obtained from the new QCD sum rule and the values of many other analogous constants for transitions of various currents into baryons.

B: nonleptonic decay
nonleptonic decay: B
B: width
baryon: pair production
pair production: baryon
baryon: wave function
quantum chromodynamics: sum rule
current: chiral
CKM matrix matrix
numerical calculations: interpretation of experiments
