The first measurement of the left-right cross section asymmetry in Z0 boson production

Creators

Description

The first measurement of the left-right cross section asymmetry (ALR) in Z degrees boson production has been made with the SLAC Large Detector (SLD) at the SLAC Linear Collider (SLC). The measurement was performed at a center-of-mass energy (Ecm) of 91.55 GeV with a longitudinally polarized electron beam. The average beam polarization was (22.4 ± 0.6)%. Using a sample of 10,224 Z degrees decays, ALR is measured to be 0.102 ± 0.044(stat) ± 0.003(syst), which determines the effective electroweak mixing angle to be sin2θWeff = 0.2375 ± 0.0056(stat) ± 0.0004(syst)
