Abstract

We use conditions for unitarity cancellations to constrain the couplings of the top and bottom quarks to Kaluza-Klein modes in Higgsless models of electroweak symmetry breaking. An example for the mass spectrum of quark resonances in a theory-space model is given and the implications for the collider phenomenology in the top sector are discussed, comparing to signatures of little Higgs and strong electroweak symmetry breaking models.
