Available in PDF, EPUB and Kindle. Book excerpt: The first measurement of the left-right cross section asymmetry (A{sub LR}) in Z° 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 (E{sub cm}) 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° decays, A{sub LR} is measured to be 0.102 ± 0.O44(stat) ± 0.003(syst), which determines the effective electroweak mixing angle to be sin2 [theta]{sub W}{sup eff} = 0.2375 ± 0.0056(stat) ± 0.0004(syst).

Book excerpt: The left-right cross section asymmetry for Z boson production in e[sup +]e[sup -] annihilation (A[sub LR]) has been measured at E[sub cm] = 91.55 GeV with the SLD detector at the SLAC Linear Collider (SLC) using a longitudinally polarized electron beam. The electron polarization was continually monitored with a Compton scattering polarimeter, and was typically 22%. We have accumulated a sample of [approximately]10,200 Z events. We find that A[sup LR] = 0.100 [plus minus] 0.044 [plus minus] 0.003 where the first error is statistical and the second is systematic. From this measurement, we determine the weak mixing angle defined at the Z boson pole to be sin[sup 2][theta](lept/w) = 0.2378 [plus minus] 0.0056.

This book was released on 1994 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors present a precise measurement of the left-right cross section asymmetry (A{sub LR}) for Z boson production by ee− collisions. The measurement was performed at a center-of-mass energy of 91.26 GeV with the SLD detector at the SLAC Linear Collider (SLC). The luminosity-weighted average polarization of the SLC electron beam was (63.0 ± 1.1)%. Using a sample of 49,392 Z decays, they measure A{sub LR} to be 0.1628 ± 0.0071 (stat.) ± 0.0028(syst.) which determines the effective weak mixing angle to be sin2 [theta]{sub W}{sup eff} = 0.2292 ± 0.0009(stat.) ± 0.0004(syst.). They combine this result with the result obtained in 1992 and obtain sin2 [theta]{sub W}{sup eff} = 0.2294 ± 0.0010, which constitutes the best measurement of sin2 [theta]{sub W}{sup eff} in a single experiment presently available.

Book excerpt: A precise measurement of the left-right cross section asymmetry (A{sub LR}) for Z boson production by ee− 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 sin2 [theta]{sub W}{sup eff} = 0.2290 ± 0.0010.

Book excerpt: The SLAC Linear Collider (SLC) has recently been upgraded to produce, accelerate, and collide a spin polarized electron beam. The average beam polarization during the 1992 run was (22.4 [plus minus] 0.7)%. The SLD Collaboration used the polarized beam to perform the first measurement of the left-right cross section asymmetry (A[sub LR]) for Z boson production by e[sup +]e[sup [minus]] collisions. The measurement was performed at a center-of-mass energy of 91.55 GeV with a sample of 10,224 Z decays. The measured value of A[sub LR] is 0.100 [plus minus] 0.044(stat.) [plus minus] O.004(syst.) which determines the effective weak mixing angle to be sin[sup 2][theta][sub W][sup eff] = 0.2378 [plus minus] 0.0056(stat.) [plus minus] 0.0005(syst.).
