The phenomenological extraction of Transverse Momentum Dependent (TMD) parton distributions is key to probing the three-dimensional structure of hadrons and gaining deeper insights into the strong force and Quantum Chromodynamics (QCD). While TMDs are rigorously defined through QCD operators, their extraction from experimental data is complicated by the dominance of non-perturbative effects at...

In this talk, we present a description at the highest available perturbative accuracy of the complete transverse-momentum $q_T$ spectrum in low-invariant-mass Drell–Yan production, with special attention to the challenging high-$q_T$ region.
