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 correlations for different quark and nucleon polarizations.

Abstract

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 correlations for different quark and nucleon polarizations.
