A precise measurement of the partial decay width ratio Rb0 = Γbb̄/Γhad
- Abstract:
- The partial decay width of the Z to bb̄ quark pairs has been measured by the DELPHI detector at LEP using data taken in the years 1992 to 1995. Decays of b-hadrons were tagged by several methods using tracks with large impact parameters and/or reconstructed secondary vertices, complemented by event shape variables. Combining these methods in a multivariate analysis the value Γ(Z → bb̄)/Γ(Z → had) = 0.21634 ± 0.00067 (stat) ± 0.00060 (syst) was obtained, where the cc̄ production fraction was fixed to its Standard Model value.
