SIDIS Asymmetries in Quark-Diquark Model

Understand

Some properties of intrinsic transverse momentum dependent nucleon distribution functions are considered in the simple quark-diquark model.

• The transverse target polarization dependent asymmetries for SIDIS are calculated and compared with recent results of COMPASS.
• The model describes well the measured asymmetries.
• Generalization of quark-diquark model for Sivers function is discussed.
