Abstract
The partial decay width of the Z to <b(b)over bar> quark pairs has bee n measured by the DELPHI detector at LEP. B-hadrons, containing b-quar ks, were tagged by several methods using tracks with large impact para meters to the primary vertex complemented sometimes by event shape var iables or using leptons with high transverse momentum relative to the hadron, In order to reduce the systematic uncertainties, in all method s the b-tagging efficiency has been extracted directly from the data. Combining all methods, the value: Gamma(<b(b)over bar>)/Gamma(had) = 0 .2216 +/- 0.0016(stat.) +/- 0.0021(syst.) was found, where the <c(c)ov er bar> production fraction was fixed to its Standard Model value.
