Abstract
Describing qT-dependent SIDIS distributions requires consideration of two different regimes which involve two different factorization schemes. In both cases, the necessary ingredients include parton distribution and fragmentation functions (PDFs and FFs), which are traditionally extracted in statistical analyses with collinear observables. We will present examples of how the errors in the extraction of collinear PDFs and FFs may affect the successful description of the qT-dependent SIDIS distributions.
