Improved direct measurement of the parity-violation parameter Ab using a mass tag and momentum-weighted track charge
The highly polarized SLC electron beam and precise vertexing capabilities of the SLD detector were exploited to perform a direct measurement of Ab=0.906±0.022(stat)±0.023(syst), from the 1996-1998 SLD data sample. Combined with previously published result based on the 1993-1995 data sample, Ab=0.907...
