We quantify the expected sensitivity to Z′ boson effects in the W boson pair production at the LHC. The diboson production allows to place stringent constraints on the Z − Z′ mixing angle. We find that the present LHC bounds on the mixing angle obtained at the LHC energy of 8 TeV and integrated luminosity of 20 fb−1 are of the same order as those derived from the electroweak data. Further improvement on the constraining of this mixing can be achieved from the analysis of data at the LHC with nominal energy and luminosity, 14 TeV and 100 fb−1.
