Fragmentation fractions of two-body b-baryon decays
We study the fragmentation fractions (fBb) of the b-quark to b-baryons (Bb). By the assumption of fΛb/(fu+fd)=0.25±0.15 in accordance with the measurements by LEP, CDF and LHCb Collaborations, we estimate that fΛb=0.175±0.106 and fΞb−,0=0.019±0.013. From these fragmentation fractions, we derive B(Λb...
