Measurement of inclusiveB meson decays into baryons

The decay ofB mesons into the baryonsp, ? and?^- has been studied. The measured inclusive branching ratios for these decays are Br(B?p X) =(8.2±0.5_-1.0^+1.3)%, Br(B??X)=(4.2±0.5±0.6)% and Br(B??^-X)<0.51% at the 90% confidence level.

From this one can derive a total baryonic branching ratio Br(B?baryons) of (7.6±1.4)%.
