Description

Sivers function is a fundamental TMD which allows to investigate the 3D structure of polarized nucleons. We present a recent extraction of this function from azimuthal asymmetries in semi-inclusive DIS. This study includes for the first time TMD evolution contributions and a parametrization of unpolarized TMDs determined directly from data. Through this analysis we can obtain a tomography of the internal structure of nucleons in momentum space. Finally, We discuss a possible way to determine quark angular momentum through its relation with the extracted distribution.
