Available in PDF, EPUB and Kindle. Book excerpt: An extensive experimental program to study spin physics at low and moderate four-momentum transfer, Q{sup 2}, is in progress at Jefferson Lab. In this regime, soft processes as resonance excitation and higher twist contribution play a dominant role and the measurement of spin observables is a fundamental tool to understand such phenomena and identify the relevant degrees of freedom. In these proceedings I will describe the ongoing experimental program and I will discuss preliminary and final results.

Book excerpt: Two recent experiments in Hall A of Jefferson Lab have explored the spin structure of the neutron. Experiment E99-117 focused on measuring the neutron spin asymmetry A1(superscript n) to high precision at x = 0.33, 0.47 and 0.60 and Q2 = 2.7, 3.5 and 4.8 (GeV/c)2, respectively. A second experiment, E97-103, measured the polarized spin structure function g2(superscript n) at x (almost equal to) 0.2 for five values of the momentum transfer Q2 from 0.58 to 1.36 (GeV/c)2. Preliminary results from these experiments will be presented and compared to theoretical models.

Book Synopsis Spin Physics With Clas At Jefferson Laboratory by :
Download or read book Spin Physics With Clas At Jefferson Laboratory written by and published by . This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Inelastic scattering using polarized nucleon targets and polarized charged lepton beams allows the extraction of spin structure functions that provide information about the spin structure of the nucleon. A program designed to study such processes at low and intermediate Q2 for the proton and deuteron has been pursued by the CLAS Collaboration at Jefferson Lab since 1998. The data with high statistical precision and extensive kinematic coverage allows us to better constrain the polarized parton distributions and to accurately determine various moments of g1 as a function of Q2. The latest results are presented, illustrating our contribution to the world data, with comparisons of the data with NLO global fits, phenomenological models, chiral perturbation theory, the GDH and Bjorken sum rules, and tests of global duality.

Book excerpt: Inelastic scattering using polarized nucleon targets and polarized charged lepton beams allows the extraction of double and single spin asymmetries that provide information about the helicity structure of the nucleon. A program designed to study such processes at low and intermediate Q2 for the proton and deuteron has been pursued by the CLAS Collaboration at Jefferson Lab since 1998. Our inclusive data with high statistical precision and extensive kinematic coverage allow us to better constrain the polarized parton distributions and to accurately determine various moments of spin structure function g1 as a function of Q2. The latest results are shown, illustrating our contribution to the world data, with comparisons of the data with NLO global fits, phenomenological models, chiral perturbation theory and the GDH and Bjorken sum rules. The semi-inclusive measurements of single and double spin asymmetries for charged and neutral pions are also shown, indicating the importance of the orbital motion of quarks in understanding of the spin structure of the nucleon.

Book Synopsis Transverse Spin Physics by : Vincenzo Barone
Download or read book Transverse Spin Physics written by Vincenzo Barone and published by World Scientific. This book was released on 2003-01-29 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to the theory and phenomenology of transverse-spin effects in high-energy hadronic physics. Contrary to common past belief, it is now rather clear that such effects are far from irrelevant. A decade or so of intense theoretical work has shed much light on the subject and brought to surface an entire class of new phenomena, which now await thorough experimental investigation. Over the next few years a number of experiments world-wide (at BNL, CERN, DESY and JLAB) will run with transversely polarised beams and targets, providing data that will enrich our knowledge of the transverse-spin structure of hadrons. It is therefore timely to assess the state of the art, and this is the principal aim of the volume.An outline of the book is as follows. After a few introductory remarks (Chapter 1), attention is directed in Chapter 2 to transversely polarised deeply-inelastic scattering (DIS), which probes the transverse spin structure function g2. This existing data are reviewed and discussed (for completeness, a brief presentation of longitudinally polarised DIS is also provided). In Chapter 3 the transverse-spin structure of the proton is illustrated in detail, with emphasis on the transversity distribution and the twist-three parton distribution contributing to g2. Model calculations of these quantities are also presented. In Chapter 4, the QCD evolution of transversity is studied at leading and next-to-leading order. Chapter 5 illustrates the g2 structure function and its related sum rules within the framework of perturbative QCD. The last three chapters are devoted to the phenomenology of transversity, in the context of Drell-Yan processes (Chapter 6), inclusive leptoproduction (Chapter 7) and inclusive hadroproduction (Chapter 8). The interpretation of some recent single-spin asymmetry data is discussed and the prospects for future measurements are reviewed.
