| Abstract: The first search for a heavy neutral spin-1 gauge boson (Z') produced via vector boson fusion processes is presented. The analysis considers scenarios in which the Z' boson has non-universal fermion couplings, favoring higher-generation fermions. This offers a new physics phase space not yet fully explored at the LHC. The analysis is performed using LHC data at √s= 13 TeV, collected from 2016 to 2018, corresponding to an integrated luminosity of 138 fb−1. The data are consistent with the standard model expectation. Upper limits are set on the product of the Z' cross section and the branching fraction for a Z' boson decaying to ττ or WW. Masses below 2.45 TeV are excluded, depending on the Z' coupling to weak bosons. | ||
