Transverse momentum dependent parton distributions and azimuthal asymmetries in light-cone quark models

TL;DR

This paper reviews how light-cone quark models describe the spin and orbital angular momentum of nucleons through transverse momentum dependent parton distributions, comparing model predictions with experimental data on azimuthal asymmetries.

Contribution

It provides a comprehensive review of T-even transverse momentum dependent distributions in light-cone quark models and compares model predictions with experimental measurements.

Findings

Model results agree well with existing experimental data.

Predictions are made for future experiments at CLAS, COMPASS, and HERMES.

Insights into the spin and orbital structure of the nucleon are discussed.

Abstract

We review the information on the spin and orbital angular momentum structure of the nucleon encoded in the T-even transverse momentum dependent parton distributions within light-cone quark models. Model results for azimuthal spin asymmetries in semi-inclusive lepton-nucleon deep-inelastic scattering are discussed, showing a good agreement with available experimental data and providing predictions to be further tested by future CLAS, COMPASS and HERMES data.
