Measurement of inclusiveB meson decays into baryons

The decay ofB mesons into the baryonsp, Λ andΞ− 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→ΛX)=(4.2±0.5±0.6)% and Br(B→Ξ−X)<0.51% at the 90% confidence level. In addition investigations onp\(\bar p\), andΛ\(\bar p\) andΛ\(\bar \Lambda \) correlations were performed, yielding an approximately equal rate of protons and neutrons. From this one can derive a total baryonic branching ratio Br(B→baryons) of (7.6±1.4)%.
