Transverse-momentum-dependent parton distributions up to N$^3$LL from Drell-Yan data

Understand

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 N$^3$LL order, and we include non-perturbative contributions.
• These ingredients allow us to obtain a remarkable agreement with the data.
