Abstract

The article studies the production of 𝑍-bosons in proton-proton collisions at LHC collider energies. Production cross sections and transverse momentum spectra of 𝑍-bosons have been calculated, as well as lepton angular coefficients as functions of the transverse momentum of the 𝑍-boson. Calculations were performed using the parton Reggeization approach (PRA) within the framework of the leading approximation in the strong coupling constant (𝑄¯ 𝑄 → 𝑍), taking into account the next to leading order correction from processes of quark-gluon scattering (𝑅𝑄 → 𝑍𝑞). Numerical modeling was performed using Monte-Carlo generator KaTie. The calculation results are compared with experimental data from the ATLAS collaboration.
