Description

In this talk, we discuss the latest results on the extraction of Transverse-Momentum-Dependent (TMD) distributions from global analyses of presently available experimental data. In particular, we focus on the simultaneous extraction of TMD Parton Distribution Functions (TMD PDFs) and Fragmentation Functions (TMD FFs) from global fits of semi-inclusive DIS and Drell-Yan data sets in the framework of the MAP Collaboration, and we discuss the differences from the results obtained by other groups.
