Abstract (data abstract)
SLAC-SLC. First measurement of the left-right cross section asymmetry for Z boson production by e+ e- collisions, using longitudinally polarized electron beam with average beam polarization of (22.4 +- 0.6) pct. From the results the effective weak mixing angle is determined to be 0.2378 +- 0.0056 +- 0.0005.
