Spin Structure of the Nucleon A
نویسنده
چکیده
New experimental results on the spin dependent structure functions g 1 and g 2 which are determined from deep-inelastic scattering experiments at CERN, SLAC and DESY are reported. These results are used to evaluate the Bjorken sum rule and the singlet axial charge a 0. Results are discussed in the framework of next-to-leading order perturbative QCD. The role of the polarised gluons in the interpretation of the results on a 0 is emphasised. New experiments which aim to determine gluon polarisation are shortly described.

In this paper, we reformulate three-nucleon breakup scattering in leading order approximation by considering spin-isospin degrees of freedom. At first, considering the inhomogeneous part of Faddeev equation, which is a valid approximation in high and intermediate energles, we present the Faddeev equation as a function of vector Jacobi momenta and spin and isospin quantum numbers. In this new fo...

In this paper, we calculate nuclear structure function and EMC effect of 40Ca and 56Fe nuclei. To achive the goals, we consider Fermi motion and binding energy contrbiution in the harmonic oscillator model. In this model, harmonic oscillator parameter ħω related to shells root mean square radius and for free nucleon structure functions, is obtained from GRV’s free nucleon structure functions. ...
متن کاملStructure of the Nucleon Spin on the Light Cone
The spin structure of the nucleon is studied in a light-cone description of the nucleon where the Fock expansion is truncated to consider only valence quarks. Transverse momentum dependent parton distributions and transverse-spin densities, defined through the generalized parton distributions in the impact parameter space, are investigated as new tools to reveal the spin-spin and spin-orbit cor...
متن کاملSpin Structure of the Proton and Transverse Momentum Dependent distributions
Transverse Momentum Dependent Distributions (TMDs) describe the spin structure of the proton. At leading twist spin structure of spin-1/2 hadron can be described by 8 TMDs. TMDs reveal three-dimensional distribution of partons inside polarised nucleon. Experimentally these functions can be studied in polarised experiments using Spin Asymmetries in particular Single Spin Asymmetries (SSAs). We d...
متن کاملThe nucleon spin structure in a simple quark model
We investigate the spin structure of the nucleon in an extended Jaffe-Lipkin quark model. In addition to the conventional 3q structure, different (3q)(QQ̄) admixtures in the nucleon wavefunction are also taken into account. The contributions to the nucleon spin from various components of the nucleon wavefunction are discussed. The effect due to the Melosh-Wigner rotation is also studied. PACS nu...
متن کاملHermes Measurement of the Spin Structure of the Nucleon
The HERMES experiment at the DESY Laboratory in Hamburg, Germany is designed to probe the spin structure of the nucleon by using deep inelastic scattering (DIS) of longitudinally polarized positrons on longitudinally and transversely polarized targets. The HERMES spectrometer has the ability to not only identify the scattered DIS positrons but as well the hadrons in coincidence with the scatter...
