Measurement of the multiplicity of gluons splitting to bottom quark pairs in hadronic Z(0) decays

Abstract:

An inclusive measurement of the average multiplicity of bb̄ pairs from gluons, gbb̄, in hadronic Z0 events collected by the DELPHI experiment at LEP, is presented. A counting technique, based on jet b-tagging in 4-jet events, has been used. Looking for secondary bottom production in events with production of any primary flavour, by requiring two b-tagged jets in well defined topological configurations, gave gbb̄ = (0.21 ± 0.11(stat) ± 0.09(syst))%. This result was checked with a different met...
