Published online: 23 January 2015
The investigation of the partonic degrees of freedom beyond collinear approximation (toward a 3D description of the hadron structure) has been gaining increasing interest in the last decade. SIDIS reactions offer a rich phenomenology convoluting TMD parton distribution and fragmentation functions. In the recent years, several first measurements have been made that provide new insights on peculiar aspects of the parton dynamics, i.e. orbital motion and spin-orbits effects. Beyond spin asymmetries, unpolarized measurements, with their high-statistics data samples and natural connections among different fields of investigation, challenge our comprehension of TMD phenomena and are crucial for the TMD formalism assessment.
