Global Fits of Unpolarized TMDs at N3LL Accuracy
Résumé
We review the recent progress on the extraction of unpolarized TMD PDFs and TMD FFs from global data sets of Semi-Inclusive Deep-Inelastic Scattering, Drell–Yan and Z boson production. In particular, we address the tension between the low-energy SIDIS data and the theory predictions, and explore the impact of the very precise LHC data on the fit results.
