Description

Precision studies of electroweak processes at the LHC increasingly require theoretical predictions that incorporate both higher-order QCD corrections and resummation effects in the high-energy regime. In this work we present the first high-energy-resummed predictions for Drell-Yan plus jet production, providing differential spectra in rapidity and transverse momentum for $Z/\gamma^*$ bosons. Our calculation combines fixed-order NLO QCD with next-to-leading high-energy logarithmic accuracy (NLL/NLO). The framework is implemented within the JETHAD-DYnamis approach and matched to the event generator POWHEG through a new strategy that consistently incorporates polarization effects, angular correlations, and realistic lepton-level kinematics. To our knowledge, this represents the first implementation of high-energy resummation for rapidity-separated Z-boson final states. The resulting predictions improve the theoretical description of key observables relevant to current LHC measurements and to the High-Luminosity LHC program, where percent-level control of Drell-Yan distributions is essential.
