The Spin Structure of the Nucleon
This paper gives an overview of the spin structure of the nucleon with emphasis on a pedagogical presentation of the tools used to study this fundamental property of protons and neutrons. While many of the data currently available are shown, this paper is not intended to be an exhaustive summary of the field. Rather, the data are used to illustrate the concepts presented. The most recent progre...
متن کاملThe “spin” Structure of the Nucleon
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 spin carried by the quarks. The appropriate structure function has recently been measured (EMC experiment). As in this experiment, we find that the quarks do not appear to carry a large component of the nucleon spin.
متن کاملThe Spin Structure of the Nucleon
The discovery [1, 2] by the European Muon Collaboration (EMC) that the axial charge of the proton is much smaller than expected from the Ellis–Jaffe sum rule [3] implies that the nucleon spin is not simply made up by the quark spins. This surprising result was confirmed by a series of experiments: the Spin Muon Collaboration experiment at CERN [4, 5, 6], the SLAC experiments E142 [7], E143 [8],...
متن کاملThe Spin Structure of the Nucleon
We provide an introduction to the ideas of spin-dependent deep-inelastic scattering. Recent experimental results are summarised and possible explanations related to the axial anomaly presented. Further experiments that could greatly clarify the situation are also described.
متن کاملPresent Understanding of the Nucleon Spin Structure *
The present understanding of the spin structure of the nucleon is briefly reviewed. The main focus is on parton helicity distributions, orbital angular momentum of partons as defined through generalized parton distributions, as well as single spin asymmetries and time-reversal odd correlation functions.
