The pursuit of high-precision predictions for Drell-Yan processes at hadron colliders has driven substantial theoretical advancements in recent years. Experiments aim for increasingly accurate determinations of Standard Model parameters such as the weak mixing angle, the strong coupling and the W-boson mass. Central to this progress is the incorporation of higher-order QCD and electroweak corrections within fiducial phase-space regions relevant to LHC analyses. NNLO QCD predictions are now available through multiple public codes, whose reliability is crucial to achieve the precision demanded by experimental measurements. Achieving N3LO accuracy for fiducial observables, matched with next-to-next-to-next-to-leading logarithmic (N3LL) resummation, has established a new benchmark in theoretical precision, reducing uncertainties to the percent level. Complementing these efforts, the exact computation of mixed QCD-electroweak corrections plays a central role in correctly interpreting high-precision Drell-Yan data and extracting fundamental Standard Model parameters. In this seminar, I will discuss recent progress toward a fully consistent, high-accuracy description of Drell-Yan pair production that will underpin current and future precision measurements at hadron colliders.
