A Preliminary measurement of the gluon splitting rate into b\bar{b} pairs in hadronic Z0 decays
- SLAC
We present a measurement of the rate of gluon splitting into bottom quarks, g --> b anti-b, in hadronic Z0 decays collected by SLD from 1996 to 1998. The analysis was performed by looking for secondary bottom production in 4-jet events of any primary avor. A topological vertex mass technique was used to tag the two jets with the smallest angle between them as b/anti-b. We obtained a rate of g --> b anti-b per hadronic event to be (3.07 ± 0.71(stat:) ± 0.66(syst:)) × 10³ (preliminary).
