Estimates for the Abelian $Z'$ Couplings from the LHC Data
Abstract
In this paper, we investigate the Drell-Yan process with the intermediate heavy boson. We use a general approach to the Abelian that utilizes the renormalization-group relations between the couplings and allows to reduce the number of unknown parameters significantly. In a newly proposed strategy, we estimate the LHC-driven constraints for the couplings to lepton and quark vector currents. To do this, we calculate the -related contribution in the narrow-width approximation and compare the obtained values to the experimental data presented by the ATLAS and CMS collaborations. Our method allows to estimate the values of couplings to the and quarks and to final-state leptons.
