Book excerpt: The authors present three QCD studies performed by the SLD experiment at SLAC, utilizing the highly polarized SLC electron beam. They examined particle production differences in light quark and antiquark hemispheres, and observed more high momentum baryons and K−'s than antibaryons and K's in quark hemispheres, consistent with the leading particle hypothesis. They performed a search for jet handedness in light q- and {anti q}-jets. Assuming Standard Model values of quark polarization in Z° decays, they have set an improved upper limit on the analyzing power of the handedness method. They studied the correlation between the Z° spin and the event-plane orientation in polarized Z° decays into three jets.

Book excerpt: The authors present a measurement of the strong coupling a{sub s} derived from multijet rates using data collected by the SLD experiment at SLAC and find that a{sub s}(M{sub Z}2) = 0.118 " 0.002(stat.) " 0.003(syst.) " 0.010(theory). The authors present tests of the flavor independence of strong interactions via preliminary measurements of the ratios a{sub s}(b)/a{sub s}(udse) and a{sub s}(uds)/a{sub s}(bc). In addition, the authors have measured the difference in charged particle multiplicity between Z° --> b{bar b} and Z° --> u{bar u}, d{bar d}, s{bar s} events, and find that it supports the prediction of perturbative QCD that the multiplicity difference be independent of center-of-mass energy. Finally, they have made a preliminary study of jet polarization using the jet handedness technique.

This book was released on 2003-01-16 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the invited talks and contributed papers presented at the workshop on “Testing QCD Through Spin Observables in Nuclear Targets”, held at the University of Virginia in April 2002.The workshop was proposed in the context of the large number of experiments that have used polarized deuterons or polarized 3He to extract information about the spin parameters of the neutron. The motivation for this workshop was to study the effects of the nuclear medium on the spin properties of the bound nucleon and to explore issues in QCD that might be resolved through spin observables in nuclear targets: What is the effect of the nuclear medium on the measured asymmetries? How have the latest results on the spin structure of the nucleon and the nucleon form factors changed our thinking? What advances are anticipated in the development of polarized targets?

This book was released on 1990-08-06 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proceedings presents articles exploring the wide range of physics with can be addressed with measurements using both polarized beams and polarized targets. The conference concentrated on the physics to be done using polarized beams on polarized targets and include selected highlights on advances in the technology. Topics covered include studies of nuclear structure and few-body reactions to test fundamental symmetries, measurements of electromagnetic form factors and of the internal spin structure of nucleons, and tests of QCD.

Book excerpt: We present three measurements that exploit the highly-polarized incident electrons of the SLC facility to probe QCD and the hadronization process. We observe preliminary evidence for leading particle production in hadronic decays of the Zo to light-quark pairs. In a high-purity sample of quark jets, the momentum spectra of p, A0, and K( - ) are harder than those of p(bar), A(bar)0, and K(+), supporting the hypothesis that faster particles in jets are more likely to carry the primary quark or antiquark of the jet. Second, we present an improved limit on jet handedness, which seeks to measure the transport of quark spin through the hadronization process. Finally, we search for a correlation of the three jet event orientation with the Zo spin direction, which would indicate new physics beyond the Standard model.

Book excerpt: The International Workshop on Polarized Beams and Polarized Gas Targets was held in Cologne, Germany from June 6 to 9, 1995 as the last in a series held at 2-3 years intervals. It was attended by about 110 scientists; there were 47 invited and contributed talks, 5 round-table discussions and 17 poster contributions, all of which will appear as a written contribution in the Proceedings. The main subjects were Optically-Pumped Polarized Targets, Polarized Electron Sources, Atomic-Beam Polarized-Ion Sources, Optically-Pumped Polarized Ion Sources, Targets and Storage Rings. Significant progress and latest developments in this field were covered as well as future developments both from the technical, but also from the physics aspects.

This book was released on 2023-03-21 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Open Access book is drawn from lectures dispensed at the U.S. Particle Accelerator School (USPAS) Summer 2021 Spin Class, by experts in the field. It is an introduction to the dynamics of spin in charged particle accelerators, and to the accelerator components and spin manipulation techniques, including helical snakes and spin rotators, which enable and allow preserving beam polarization. It is aimed at graduate students or upper division undergraduate students with an interest in this multi-disciplinary field, which includes the future electron-ion collider at the Brookhaven National Laboratory, high energy lepton and proton collider projects, and other electric dipole moment search storage rings. It is also aimed at physicists or engineers working in accelerator-related fields who wish to familiarize themselves with spin dynamics and polarized beam concepts, tools, components, and purposes. This is an open access book.
