Abstract

We reinterpret WW', ZZ' and Higgs searches at the LHC in terms of a model with nonuniversal VV' couplings to fermions in order to gauge how well these searches can be applied outside the (simplified) scenarios for which they were optimized. In particular, we consider bounds from VV' searches in final states ττ\tau \tau, eνe\nu, llll and tbt b, and discuss the impact of width effects. We then show that decays of the type VVhV' \rightarrow V h yield additional bounds on the heavy vector masses and, in the case of a discovery, provide an important probe of the heavy sector. Finally, we match the low energy limit of the model to an effective theory and compare the bounds on the resulting dimension-6 operators with the direct searches discussed in this paper.
