Direct measurement of parity violation in the coupling of Z0bosons to b quarks using a mass tag and momentum-weighted track charge
Physical Review Letters 81:5 (1998) 942-946
Abstract:
We present a direct measurement of the parity-violation parameter Ab using a self-calibrating track-charge technique. In the SLAC Linear Collider Large Detector (SLD) experiment we observe hadronic decays of Z0 bosons produced in collisions between longitudinally polarized electrons and unpolarized positrons at the SLAC Linear Collider. A sample of bb events is selected using the topologically reconstructed mass of B hadrons. From our 1993–1995 sample of approximately 150 000 hadronic Z0 decays we obtain Ab = 0.911 ± 0.045(stat)±0.045(syst). © 1998 The American Physical Society.Direct measurement of parity violation in the coupling of Z0 bosons to b quarks using a mass tag and momentum-weighted track charge

Review of αs measurements
Acta Physica Polonica B 28:3-4 (1997) 701-723
Abstract:
Determinations of αs are reviewed. Current results are limited to a precision of around 3-20%, largely by theoretical uncertainties. All measurements are consistent with a 'world average' value of 0.118 ± 0.005 and there is no evidence of any discrepancy between 'low-Q2, and 'high-Q2, results.Design and performance of the SLD vertex detector: a 307 Mpixel tracking system
