Available in PDF, EPUB and Kindle. Book excerpt: My lectures at Cargese covered the very first physics results from the SLAC Linear Collider (SLC). At the time of this writing (December 1989), it seems most sensible to present a review of the results that were presented at the school in an updated form. The organization of this report will be to give a brief introduction to linear colliders and the SLC, then to describe the MARK II detector, and finally to review the current status of the three major physics topics discussed at Cargese: the Z line shape, from which we deduce the Z mass and width, and the number of neutrino species, the partonic structure of hadronic decays and a measurement of [alpha]{sub s}, and searches for new quarks and leptons. 39 refs., 27 figs., 3 tabs.

Available in PDF, EPUB and Kindle. Book excerpt: This paper presents the measurement by the Mark II experiment at the SLAC Linear Collider of the parameters of the Z boson resonance. The results are updated from those presented at the SLAC Summer Institute to include all data presented in the most recent Mark II publication, consisting of 19 nb−1 of data at ten different center-of-mass energies between 89.2 and 93.0 GeV. The resonance parameters are extracted by measuring the Z production cross section at a series of center-of-mass energies (scan points) near the Z peak, then fitting these data with the theoretical cross section. The four major aspects of the analysis are the determination at each scan point of the center-of-mass energy (E), the integrated luminosity, the number of Z decays and the expected cross section as a function of the resonance parameters, such as mass and width. I will discuss each of these steps in turn, after a brief description of the Mark II detector, then conclude with the results of the analysis. 7 refs., 9 figs., 3 tabs.

Book excerpt: Z[degrees] bosons have been produced by collisions of longitudinally polarized electrons with unpolarized positrons at the SLAC Linear Collider and their decays have been recorded by the SLD experiment. We present preliminary measurements of the properties of the resulting Z[degrees] decays into multi-hadronic final states. We find good agreement with the predictions of perturbative QCD and fragmentation models.

Available in PDF, EPUB and Kindle. Book excerpt: We have measured the resonance parameters of the Z boson using 480 hadronic and Leptonic Z decays collected by the Mark II Detector at the Stanford Linear Collider. We find the Mass to be 91.14 ± 0.12 GeV/c2, and the width to be 2.42{sup +0.45}{sub -0.35} GeV. If we constrain the visible width to its Standard Model value, we find a partial width to invisible decay modes corresponding to 2.8 ± 0.6 neutrino species with a 95% confidence level limit of 3.9. 9 refs., 1 fig., 4 tabs.

Download or read book Electron Positron Physics at the Z written by M. G. Green and published by CRC Press. This book was released on 1998 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive summary of studies of the Z boson in electron positron interactions. The results that have been obtained have achieved unprecedented accuracy and have firmly established the Electroweak Standard Model as the cornerstone of our current understanding of modern particle physics. The book introduces the background to the Standard Model and the role of the Z boson and describes briefly the accelerators and experiments involved in these results. The five main chapters deal with the detailed measurements of the electroweak parameters of the Z, the study of QCD, heavy quark physics, tau lepton physics and the search for new particles. Each chapter ends with a summary and outlook to prospects of future accelerators. Most of the results are from the first six years running at the first phase of electron positron collider, LEP, at energies corresponding to the Z mass, but results from the SLAC Linear Collider and some new results at higher energies are also included.

Available in PDF, EPUB and Kindle. Book excerpt: This work presents measurements of the parity-violation parameters A{sub c} and A{sub b} made at the Z pole. These measurements include the data taken with the SLD detector at the SLAC Linear Collider (SLC) during the period 1996-98. Heavy flavor events are selected with high efficiency and purity by searching for displaced vertices, identified with the SLD precision CCD vertex detector. Two methods are used for quark/antiquark discrimination: the net charge of the displaced vertex, and tracks in the displaced vertex identified as kaons by the SLD Cherenkov Ring Imaging Detector (CRID). The signal purities and analyzing powers are calibrated from the data to reduce the systematic errors and avoid experimental bias. The results are A{sub c} = 0.673 " 0.029 " 0.023 and A{sub b} = 0.919 " 0.018 " 0.017, where the first error is statistical and the second systematic. Fits to the electroweak data performed by the LEP Electroweak Working Group are used to study the consistency of the Standard Model, and to constrain the mass of the Standard Model Higgs boson.
