[SLAC] [SLAC Pubs and Reports] SLAC-PUB-8401A High-Precision Measurement of the Left-Right Z Boson Cross-Section Asymmetry Abstract % insert abstract here We present a measurement of the left-right cross-section asymmetry ($\alr$) for $\zo$ boson production by \ee\ collisions. The measurement includes the final data taken with the SLD detector at the SLAC Linear Collider (SLC) during the period 1996-1998. Using a sample of 383,487 $\zo$ decays collected during the 1996-1998 runs we measure the pole-value of the asymmetry, $\alro$, to be 0.15056$\pm$0.00239 which is equivalent to an effective weak mixing angle of $\swein=0.23107\pm0.00030$. Our result for the complete 1992-1998 dataset comprising 537 thousand $\zo$ decays is $\swein=0.23097\pm0.00027$.
