Description

We present the most recent extraction of unpolarized transverse-momentum-dependent (TMD) parton distribution functions (PDFs) and TMD fragmentation functions (FFs) from global data sets of Semi-Inclusive Deep-Inelastic Scattering (SIDIS), Drell-Yan and Z boson production. The fit is performed at the N$^3$LL logarithmic accuracy in the resummation of q$_T$-logarithms and features flexible non-perturbative functions, which allow to reach a very good agreement between theory and the experimental data. In particular, we address the tension between the low-energy SIDIS data and the theory predictions.
