Available in PDF, EPUB and Kindle. Book excerpt: One of the main challenges in nuclear and particle physics in the last 20 years has been to understand how the proton''s spin is built up from its quark and gluon constituents. Quark models generally predict that about 60% of the proton''s spin should be carried by the spin of the quarks inside, whereas high energy scattering experiments have shown that the quark spin contribution is small OCo only about 30%. This result has been the underlying motivation for about 1000 theoretical papers and a global program of dedicated spin experiments at BNL, CERN, DESY and Jefferson Laboratory to map the individual quark and gluon angular momentum contributions to the proton''s spin, which are now yielding exciting results. This book gives an overview of the present status of the field: what is new in the data and what can be expected in the next few years. The emphasis is on the main physical ideas and the interpretation of spin data. The interface between QCD spin physics and the famous axial U(1) problem of QCD (eta and etaprime meson physics) is also highlighted. Sample Chapter(s). Chapter 1: Introduction (159 KB). Contents: Spin Experiments and Data; Dispersion Relations and Spin Sum Rules; g 1 Spin Sum Rules; Fixed Poles; The Axial Anomaly, Gluon topology and g (0) A; Chiral Symmetry and Axial U(1) Dynamics; QCD Inspired Models of the Proton Spin Problem; The Spin-Flavour Structure of the Proton; QCD Fits to g 1 Data; Polarized Quark Distributions; Polarized Glue o g(x, Q 2 ); Transversity; Deeply Virtual Compton Scattering and Exclusive Processes; Polarized Photon Structure Functions; Conclusions and Open Questions: How Does the Proton Spin?. Readership: Academics, as well as physicists working on particle and nuclear physics at the interface of theory and experiment.

This book was released on 2002 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have measured the spin structure functions g2{sup p} and g2{sup d} and the virtual photon asymmetries A2{sup p} and A2{sup d} over the kinematic range 0.02 (less-than or equal to) x (less-than or equal to) 0.8 and 0.7 (less-than or equal to) Q2 (less-than or equal to) 20 GeV2 by scattering 29.1 and 32.3 GeV longitudinally polarized electrons from transversely polarized NH3 and 6LiD targets. Our measured g2 approximately follows the twist-2 Wandzura-Wilczek calculation. The twist-3 reduced matrix elements d2{sup p} and d2(superscript n) are less than two standard deviations from zero. The data are inconsistent with the Burkhardt-Cottingham sum rule if there is no pathological behavior as x --> 0. The Efremov-Leader-Teryaev integral is consistent with zero within our measured kinematic range. The absolute value of A2 is significantly smaller than the A2

Available in PDF, EPUB and Kindle. Book excerpt: The spin structure function g2(x, Q2) and the virtual photon asymmetry A2(x, Q2) were measured for the proton using deep inelastic scattering. The experiment was conducted at the Stanford Linear Accelerator Center (SLAC), where longitudinally polarized electrons at 29.1 and 32.3 GeV were scattered from a transversely polarized NH3 target. Large data sets were accumulated using three independent spectrometers covering a kinematic range 0.02 (less-than or equal to) x (less-than or equal to) 0.8 and 1 (less-than or equal to) Q2 (less-than or equal to) 20 (GeV/c)2. This new data is the first data precise enough to distinguish between current models for the proton. The structure function g2{sup p} was found to be reasonably consistent with the twist-2 Wandzura-Wilczek calculation. The Q2 dependence of g2 approximately follows the Q2 dependence of g2{sup WW}, although the data are not precise enough to rule out no Q2 dependence. The absolute value for A2{sup p} was found to be significantly smaller than the Soffer limit over the measured range. The virtual photon asymmetry A2 was also found to be inconsistent with zero over much of the measured range.
