Description
Recent studies of inclusive Higgs rates at N$^3$LO have shown that high-energy resummation effects can reach the 10\% level, reinforcing the idea that electroweak observables from LHC to FCC energies are increasingly shaped by high-energy QCD dynamics. Here we present the first high-energy-resummed predictions for Drell–Yan plus jet production, providing rapidity and transverse-momentum spectra for $Z/\gamma^*$ bosons. Our NLO calculation is matched to next-to-leading energy-logarithmic accuracy (NLL/NLO) and complemented by a new JETHAD-DYnamis–POWHEG matching strategy that incorporates polarization, angular dynamics, and realistic lepton-level kinematics. To our knowledge, this is the first implementation of high-energy resummation for rapidity-separated $Z$-boson final states. The framework improves predictions for key electroweak precision observables, directly relevant to current LHC analyses and to the High-Luminosity LHC, where percent-level control of Drell–Yan distributions is required.
