Azimuthal spin asymmetries in light-cone constituent quark models

Understand

We present results for all leading-twist azimuthal spin asymmetries in semi-inclusive lepton-nucleon deep-inelastic scattering due to T-even transverse-momentum dependent parton distribution functions on the basis of a light-cone constituent quark model.

• Attention is paid to discuss the range of applicability of the model, especially with regard to the scale dependence of the observables and the transverse-momentum dependence of the distributions.
• We find good agreement with available experimental data and present predictions to be further tested by future CLAS, COMPASS and HERMES data.
