- W343914892 abstract "We present an improved direct measurement of the parity-violation parameter A{sub b} in the Z boson-b quark coupling using a self-calibrating track-charge technique applied to a sample enriched in Z {yields} b{bar b} events via the topological reconstruction of the B hadron mass. Manipulation of the SLC electron-beam polarization permits the measurement of A{sub b} to be made independently of other Z-pole coupling parameters. From the 1996-98 sample of 400,000 hadronic Z decays,produced with an average beam polarization of 73.4%, we find A{sub b} = 0.906 {+-} 0.022(stat.) {+-} 0.023(syst.)." @default.
