摘要
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 (NLL)-L-3 order, and we include non-perturbative contributions. These ingredients allow us to obtain a remarkable agreement with the data.
