We present the most recent global extraction of unpolarized pro-ton Transverse Momentum Dependent Parton Distribution Functions (TMD PDFs) and Fragmentation Functions from experimental data sets of Semi-Inclusive Deep -Inelastic Scattering, Drell-Yan and Z-boson production. We also present an ex-traction of the pion TMD PDFs from all available data of unpolarized pion-nucleus Drell-Yan processes. Both fits are performed at next-to-next-to-next-to-leading log-arithmic (N3LL) accuracy.

Abstract
We present the most recent global extraction of unpolarized pro-ton Transverse Momentum Dependent Parton Distribution Functions (TMD PDFs) and Fragmentation Functions from experimental data sets of Semi-Inclusive Deep -Inelastic Scattering, Drell-Yan and Z-boson production. We also present an ex-traction of the pion TMD PDFs from all available data of unpolarized pion-nucleus Drell-Yan processes. Both fits are performed at next-to-next-to-next-to-leading log-arithmic (N3LL) accuracy.File in questo prodotto:
