Z-Boson p_T-Spectrum and Lepton Angular Coefficients in the LO High-Energy Factorization with the Real NLO Correction

We study Z boson production in the high-energy proton-proton collisions. Z boson \({{p}_{T}}\) -spectrum and lepton angular coefficients are calculated in the parton Reggeization approach using event generator KaTie. We find good agreement of our predictions with the recent data from LHCb collaboration at the \(\sqrt s = 13\) TeV
