MEASUREMENT OF GAMMA(B(B)OVER-BAR)/GAMMA(HAD) USING IMPACT PARAMETER MEASUREMENTS AND LEPTON IDENTIFICATION

1995 
The partial decay width of theZ to\(b\bar b\) quark pairs has been measured by the DELPHI detector at LEP.b-hadrons, containingb-quarks, were tagged by leptons with high transverse momentum relative to the hadron or by tracks with large impact parameters to the primary vertex.
