We have made the first measurement of the double-inclusive B/B energy distribution in e + e - annihilations, using a sample of 400000 hadronic Z 0 -decay events recorded in the SLD experiment at SLAC between 1996 and 1998. The small and stable SLC beam spot and the CCD-based vertex detector were used to reconstruct B/B-decay vertices with high efficiency and purity, and to...
We have measured gluon splitting into bottom quarks, g→b b ̄, in hadronic Z 0 decays collected by SLD between 1996 and 1998. The analysis was performed by looking for secondary bottom production in 4-jet events of any primary flavor. 4-jet events were identified, and in each event a topological vertex-mass technique was applied to the two jets closest in angle in order to identify them as...
