Precision measurements of the production cross-sections of W/Z boson at LHC provide important tests of perturbative QCD and information about the parton distribution functions for quarks within the proton. This talk will present recent differential Z+jets results in extreme phase-spaces with high pT jets. The measurement is compared to the state-of-the-art NNLO theoretical predictions. If available, we will also present measurements of Z decays to a pair of leptons and a photon, which is a sensitive test of the kinematics of final-state QED radiation.
