Abstract

We consider a four site Higgsless model based on the SU(2)_L\ifmmode×\else\texttimes\fiSU(2)₁\ifmmode×\else\texttimes\fiSU(2)₂\ifmmode×\else\texttimes\fiU(1)_Y gauge symmetry, which predicts two neutral and four charged extra gauge bosons, Z_1,2 and W_1,2^\ifmmode±\else\textpm\fi. We compute the properties of the new particles, and derive indirect and direct limits on their masses and couplings from the CERN LEP and Tevatron data. In contrast to other Higgsless models, characterized by fermiophobic extra gauge bosons, here sizeable fermion-boson couplings are allowed by the electroweak precision data. The prospects of detecting the new predicted particles in the favored Drell-Yan channel at the CERN LHC are thus investigated. The outcome is that all six extra gauge bosons could be discovered in the early stage of the LHC low-luminosity run.
