    This article reviews our present understanding of QCD spin physics: the proton spin puzzle and new developments aimed at understanding the transverse structure of the nucleon. Present experimental investigations of the nucleon’s internal spin structure, the theoretical interpretation of the different measurements, and the open questions and challenges for future investigation are discussed.   We review the present understanding of the spin structure of protons and neutrons, the fundamental building blocks of nuclei collectively known as nucleons. The field of nucleon spin provides a critical window for testing Quantum Chromodynamics (QCD), the gauge theory of the strong interactions, since it involves fundamental aspects of hadron structure which can be probed in detail Cited by:

    We will discuss here an indirect lattice evaluation of the baryon axial singlet current matrix element. This quantity may be related to the fraction of nucleon. The measurements of the spin structure functions for the proton and neutron are reviewed. Recent high–precision data have allowed the Bjorken sum rule to be verified to within ca. 10% accuracy, providing a rigorous test of quantum chromodynamics, the current theory of strong data show that there is a deficit between the spin carried by the quarks and the spin of the nucleon Cited by: 1.

From its early beginnings at SLAC in the 's, the study of nucleon spin structure using polarized lepton beams and polarized nucleon targets spin structure of the nucleon book 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.

Attempting to understand the origin of the intrinsic spin of the proton and neutron has been an active area of both experimental and theoretical research for the past twenty years. With the confirmation that the proton and neutron were not elementary particles, physicists were challenged with the task of explaining the nucleon’s spin in terms of its by: The Spin Asymmetries of the Nucleon Experiment measured two double spin asymmetries using a polarized proton target and polarized electron beam at two beam energies, and GeV.

Since the nucleon is a building block for all atomic nuclei, there is a need to analyse the its structure in order to fully understand the essential properties of all atomic nuclei.

After more than forty years of research on the nucleon, both the experimental and theoretical situations have matured to a point where a synthesis of the results.

The field of nucleon spin provides a critical window for testing Quantum. Nucleon spin is being extensively studied at JLab [], addressing fundamental questions unanswered by earlier generations of experiments.

While previous experiments made important contributions to our understanding of the nucleon spin (for example that quark spins alone cannot explain it), crucial questions such as the role of gluon polarization and quark orbital angular momentum remained.

the nucleon spin structure remains a most active aspect of QCD research, involving important advances such as the developments of generalized parton distributions (GPD) and transverse momentum distributions (TMD).
