The left-right forward-backward asymmetry for B quarks at the SLD

PDF Version Also Available for Download.

Description

The left-right asymmetry for b quarks, A{sub b}, is precisely predicted by the Weinberg-Salam-Glashow model of particle interactions, now the standard model for high-energy particle physics. As a test of this model, A{sub b} is directly measured at the SLC Large Detector (SLD) by taking advantage of the unique polarized electron beam at the Stanford Linear Collider (SLC) and measuring the left-right forward-backward asymmetry of b quarks. To measure the asymmetry, b quarks are identified using muons of high total and transverse momenta. The result for the 1993 data sample of 37,843 hadronic Z`s is A{sub b} = 0.91 {+-} ... continued below

The result for the 1993 data sample of 37,843 hadronic Z`s is A{sub b} = 0.91 {+-} 0.19 {+-} 0.06, where the first error is statistical and the second systematic. This result is in agreement with the standard model prediction of A{sub b} = 0.935.
