In Higgsless models a breaking of the electroweak symmetry is realized via boundary conditions at the end-points of a fifth dimension compactified on an interval, as an alternative to the usual Higgs mechanism. As a result, there is no physical Higgs scalar in the spectrum, while the perturbative unitarity violation scale is delayed via the exchange of massive gauge bosons. From the AdS/CFT perspective, this model appears as a weakly coupled dual to strongly coupled models (i.e. walking technicolour models). We study the LHC signatures of new gauge bosons predicted in the minimal Higgsless model including the complete signal and background calculation and demonstrate that LHC can cover the whole parameter space of the model.
