Abstrakt: We present an extraction of unpolarised Transverse-Momentum-Dependent Parton Distribution Functions based on Drell-Yan production data from different experiments, including those at the LHC, and spanning a wide kinematic range. We deal with experimental uncertainties by properly taking into account correlations. We include resummation of logarithms of the transverse momentum of the vector boson up to N3LL order, and we include non-perturbative contributions. These ingredients allow us to obtain a remarkable agreement with the data. [ABSTRACT FROM AUTHOR]
