Available in PDF, EPUB and Kindle. Book excerpt: The SLAC experiment E155 was a deep-inelastic scattering experiment that scattered polarized electrons off polarized proton and deuteron targets in the effort to measure precisely the proton and deuteron spin structure functions. The nucleon structure functions g1 and g2 are important quantities that help test our present models of nucleon structure. Such information can help quantify the constituent contributions to the nucleon spin. The structure functions g1{sup p} and G1{sup d} have been measured over the kinematic range 0.01 ≤ x ≤ 0.9 and 1 ≤ Q2 ≤ 40 GeV2 by scattering 48.4 GeV longitudinally polarized electrons off longitudinally polarized protons and deuterons. In addition, the structure functions g2{sup p} and g2{sup d} have been measured over the kinematic range 0.01 ≤ x ≤ 0.7 and 1 ≤ Q2 ≤ 17 GeV2 by scattering 38.8 GeV longitudinally polarized electrons off transversely polarized protons and deuterons. The measurements of g1 confirm the Bjorken sum rule and find the net quark polarization to be [Delta][Sigma] = 0.23 ± 0.04 ± 0.6 while g2 is found to be consistent with the g2{sup WW} model.

Available in PDF, EPUB and Kindle. Book excerpt: E143 was a high precision measurement of the proton and deuteron spin structure functions g1 and g2 in SLAC's End Station A facility, with longitudinally and transversely polarized NH3 and ND3 targets, and a longitudinally polarized electron beam. The experiment was done, at beam energies of 29, 16 and 9.7 Gev. The deeply inelastic scattered electrons were detected by two independent spectrometers at 4.5{sup o} and 7{sup o} relative to the incident electron beam. At a beam energy of 29 Gev, the measurements covered the Bjorken x range from 0.03 to 0.8, and the Q2 range from 1.2 (GeV/c)2 to 9.8 (GeV/c)2 . It was found that the +"1 g1{sup p}(x, Q2)dx is more than two standard deviations away from the Ellis-Jaffe sum rule, and the corresponding deuteron integral is more than three standard deviations away from the Ellis-Jaffe's rule, but the Bjorken sum rule is consistent with the experimental data. Tests of the sum rules at different values of Q2, and the implications of these results for the quark-parton model have also been done.

Download or read book Spin Structure Functions of the Proton and Deuteron From SLAC Experiments E155 and E155X written by and published by . This book was released on 2003 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experiments E155 and E155X at SLAC were polarized deep inelastic scattering measurements of the parallel and perpendicular scattering asymmetries. We extracted the polarized structure functions g1 and g2 of the proton and deuteron. Both experiments made precision measurements through a wide range in x and Q2. These data fall into the kinematic range between existing world data and have good consistency with them. In combination with the other world data, the results for g1 allow increased constraint on NLO QCD fits to the polarized structure functions. For g2 no significant world data existed before E155X. The E155X measurement provides information about the higher twist effects in the nucleon.

Available in PDF, EPUB and Kindle. Book excerpt: From its early beginnings at SLAC in the 1970's, the study of nucleon spin structure using polarized lepton beams and polarized nucleon targets has become increasingly important in nuclear and particle physics, with current experiments at several of the world's high energy and nuclear physics laboratories (CERN, DESY, SLAC and Jefferson Lab) and with enormous related theoretical studies. The understanding of the fascinating but complicated problem of nucleon spin structure has progressed substantially, but fundamental questions remain and it can be confidently predicted that future activity will be high.The Erice Course on The Spin Structure of the Nucleon covered both the experimental and theoretical aspects of the subject, and this volume includes the lectures given at the School. In many cases the lecture material has been extended and updated by the authors. In addition, several recent publications on experimental work have been added in an appendix.
