Abstract
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 +1.3−1.0 )%, 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)%.
