SIDIS Asymmetries in Quark-Diquark Model
arXiv:0806.3804 · doi:10.1142/9789814277785_0029
Abstract
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.
