Abstract:

We measure the hadronic branching ratios of the Z0 boson into heavy quarks: Rb=ΓZ0→bb̄/ΓZ0→hadrons and Rc= ΓZ0→cc̄/ΓZ0→hadrons using a multitag technique. The measurement was performed using about 400000 hadronic Z0 events recorded in the SLC Large Detector experiment at SLAC between 1996 and 1998. The small and stable SLAC Linear Collider beam spot and the CCD-based vertex detector were used to reconstruct bottom and charm hadron decay vertices with high efficiency and purity, which enables us to measure most efficiencies from data. We obtain, Rb=0.21604±0.00098(stat.)±0.00073(syst.)0.00012(Rc) and, Rc=0.1744±0.0031(stat.)±0.0020(syst.)0.0006(Rb). © 2005 The American Physical Society.

Abstract:

Exploiting the manipulation of the SLAC Linear Collider electron-beam polarization, we present precise direct measurements of the parity-violation parameters Ac and Ab in the Z-boson-c-quark and Z-boson-b-quark coupling. Quark-antiquark discrimination is accomplished via a unique algorithm that takes advantage of the precise SLAC Large Detector charge coupled device vertex detector, employing the net charge of displaced vertices as well as the charge of kaons that emanate from those vertices. From the 1996-1998 sample of 400000 Z decays, produced with an average beam polarization of 73.4%, we find Ac = 0.673 ± 0.029(stat) ± 0.023(syst) and Ab = 0.919 ± 0.018(stat) ± 0.017(syst). © 2005 The American Physical Society.
