Status of A{sub LR} measurement at SLD

PDF Version Also Available for Download.

Description

The SLD Collaboration is making a precision measurement of the left-right asymmetry (A{sub LR}) at the SLAC Linear Collider, exploiting the significantly improved luminosity and the high electron-beam polarization of over 60%. General features of the polarized source and polarimetry are described. The experimental method is briefly presented, together with the preliminary values of the raw asymmetry, which should lead to a precision in the measurement of sin{sup 2}{theta}{sub W}{sup eff} of {plus_minus}0.0008 {plus_minus} 0.0005. The collaboration is preparing a proposal for an extended run for one million Z{sup o}s with improved polarimetry to reach an ultimate level of {delta} … continued below
