In this work we performed a phenomenological observation of new spin-1 bosons associated with the Electroweak Symmetry Breaking sector. As motivation for this analysis we have the special case of models based on the mechanism of Eletroweak Symmetry breaking via boundary conditions, which also have a tower of Kaluza-Klein vector bosons ensuring unitarity in scattering between gauge bosons.
In the phenomenological analysis we performed a model independent approach to analyze the potential of the Large Hadron Collider (LHC) in the detection of new vector bosons associated with the symmetry breaking sector. For this we studied the processes pp → l± jjE/T , l+ l′ − E/T , l′ ± l+ l− E/T and l+ l−jj (l, l′ = e, µ and j = jets) getting that the LHC has great potential for discovery or exclusion of this class of extensions to the Standard Model.
