Measurement of $R_b$ = $\Gamma_{b\overline{b}}$/$\Gamma_{had}$ using leptons, event shape and multivariable tags at LEP
The partial decay width of the Z to bb quark pairs has been precisely measured by the LEP collaborations using methods based on lifetime tags. In this paper, alternative measurements using lepton, event shape and multivariate tags are presented and the combined results are compared with the lifetime...
