Measurement of the Left-Right Cross Section Asymmetry in Z Boson Production in e+e- Collisions

PDF Version Also Available for Download.

Description

A precise measurement of the left-right cross section asymmetry (A{sub LR}) for Z boson production by e{sup +}e{sup -} collisions has been performed at the SLAC Linear Collider with the SLD detector. Data for the 1993 run, with its significant improvements in luminosity and electron beam polarization, are presented. When combined with the (less precise) 1992 result, the preliminary result for the effective weak mixing angle is sin{sup 2} {theta}{sub W}{sup eff} = 0.2290 {+-} 0.0010.
