B-MESON EXCLUSIVE DECAYS INTO BARYONS

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 → pp, Δp, ..., (ii) into one light and one charmed baryon: B → pΣc, pΛc,..., (iii) into two charmed baryons: B → Σc, Ξc, ΛcΞc,..., (iv) the decays induced by the b → s and b → d penguin contributions: B → pΣ, pΛ, ΔΣ,.... As a by-product, we present the result for the B-meson decay constant, fB, obtained from the new QCD sum rule and the values of many other analogous constants for transitions of various currents into baryons. © 1990.
