s channel production of heavy vector bosons in the Three-Site Higgsless Model — Thorsten Ohl and •Christian Speckner — Universität Würzburg

The Three-Site Higgsless Model provides a minimal example for higgsless BSM model building in which the unitarity of scattering amplitudes is ensured by the exchange of additional heavy vector bosons. Their couplings to the standard model fermions are strongly constrained by electroweak precision observables and typically very small. We demonstrate that they will nevertheless be produced at the LHC in the s-channel and determine the regions of parameter space where a discovery is possible in four fermion final states.
