Abstract
We present a first attempt at a global extraction of unpolarized partonic transverse momentum dependent (TMD) distributions and fragmentation functions from a simultaneous fit of data measured in semi-inclusive deep-inelastic scattering, Drell–Yan and Z boson production. This analysis is performed in the low transverse momentum region, at leading order in perturbative QCD, implementing TMD evolution at NLL accuracy. We test the agreement between our results and the recently published COMPASS data for muon-deuteron SIDIS multiplicities, and discuss their inclusion in a future global fit with a higher accuracy.
