This book was released on 1997-04-15 with total page 906 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experiments using highly polarized intense beams and targets, and theoretical studies of spin and polarization phenomena, are now providing us with numerous additional details of the electroweak and strong interactions and the structure of matter. The spin structure of the nucleon has been measured over wide ranges of kinematic variables, and the cross sections have been calculated to several orders in perturbative field theory. At present, the influence of the higher twist contributions, the gluon spin, and the quark orbital angular momentum are under scrutiny. Quantum chromodynamics (QCD) captures a lot of our experimental knowledge of hard polarized scattering processes. Can our understanding of such processes within QCD be further improved?Hyperons produced in high energy reactions show how puzzling strong interactions between hadrons still are. Spin observables in experiments at intermediate energy are used to test parity and charge symmetries. Will they also reveal, at low energy, a violation of time reversal symmetry? We are on the verge of using parity violation measurements at intermediate electron scattering energies to determine the amount of strange quark contributions to the neutral weak form factor of the nucleon. The polarization of the sea quarks is expected to be measured soon in W± decays produced in high energy polarized proton interactions. Will the jets in polarized Z⁰ decays show a definite handedness? These and many other topics are discussed in these proceedings.

This book was released on 2014 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: We present the first results of a new global next-to-leading order analysis of spin-dependent parton distribution functions from the most recent world data on inclusive polarized deep-inelastic scattering, focusing in particular on the large-x and low-Q2̂ regions. By directly fitting polarization asymmetries we eliminate biases introduced by using polarized structure function data extracted under nonuniform assumptions for the unpolarized structure functions. For analysis of the large-x data we implement nuclear smearing corrections for deuterium and 3He nuclei, and systematically include target mass and higher twist corrections to the g_1 and g_2 structure functions at low Q2̂. We also explore the effects of Q2̂ and W2̂ cuts in the data sets, and the potential impact of future data on the behavior of the spin-dependent parton distributions at large x.

Available in PDF, EPUB and Kindle. Book excerpt: We investigate the ambiguities in defining polarized parton distributions. We point out that in addition to the well-known renormalization scheme dependence in the unpolarized case, there are extra ambiguities in defining polarized parton distributions. These include the definition of [Gamma]5 in d-dimension and interpretation of the anomalous contribution. Here, a new renormalization/factorization scheme called UV Subtraction (UVS) is proposed. In the new UVS scheme, it exploits the freedom in renormalization to eliminate the ambiguities arising from [Gamma]5 and anomalous contribution. We also discuss the consequences of these ambiguities on the calculable short-distance partonic hard parts and corresponding physical observables in processes like polarized DIS and Drell-Yan Production.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this meeting, as with the seven previous conferences in this series, was to bring together particle and nuclear physicists to share scientific reports and discuss areas of research which overlap both their disciplines. Its relevance has steadily grown as the areas of overlap between particle and nuclear physics have increased. In addition, the success of the standard model has provided a common underpinning for both disciplines as well as similar fundamental goals. Indeed, Quantum Chromodynamics (QCD) has proven to be "the" theory of strong interactions. As such, it forms the basis for nuclear physics as well as high energy hadronic interactions. Topics included are: QCD spectroscopy and dynamics, relativistic heavy ions, QCD and nuclear structure, lepton-hadron and hadron-hadron scattering, heavy quark and heavy lepton physics, spin physics, nuclear and particle astrophysics, neutrinos, accelerators, facilities and detectors, as well as tests of fundamental symmetries.
