Production rate of bb(bar) quark pairs from gluons and bb(bar)bb(bar) events in hadronic Z Decays
The OPAL collaboration, G. Abbiendi
The rates are measured per hadronic Z decay for gluon splitting to bb(bar) quark pairs, g_bb, and of events containing two bb(bar) quark pairs, g_4b, using a sample of four-jet eve…
