Resumen:
I present a model with four generations of standard model fermions
propagating in a five-dimensional AdS metric. I show that it is possible
to break the electroweak symmetry via the condensation of the fourth
generation, driven by their interactions with the Kaluza-Klein gauge
bosons and by the presence of bulk higher-dimensional operators. This
dynamical mechanism results in a heavy composite Higgs, which is highly
localized towards the infrared boundary. The localization of the
fermions in the five-dimensional bulk naturally leads to the standard
model Yukawa couplings via the action of the bulk higher-dimensional
operators. I show the spectrum of the model and discuss the electroweak
precision constraints. I also study the production and detection of the
fourth generation as well as the gluon resonances at the LHC.
