In the past year, a new non-supersymmetric framework for electroweak symmetry breaking (with or without Higgs) involving SU (2) L × SU (2) R × U (1) B − L in higher dimensional warped geometry has been suggested. In this work, we embed this gauge structure into a GUT such as SO (10) or Pati–Salam. We showed recently (in hep-ph/0403143 ) that in a warped GUT, a stable Kaluza–Klein fermion can arise as a consequence of imposing proton stability. Here, we specify a complete realistic model where this particle is a weakly interacting right-handed neutrino, and present a detailed study of this new dark matter candidate, providing relic density and detection predictions. We discuss phenomenological aspects associated with the existence of other light ( ) KK fermions (related to the neutrino), whose lightness is a direct consequence of the top quark's heaviness. The AdS/CFT interpretation of this construction is also presented. Most of our qualitative results do not depend on the nature of the breaking of the electroweak symmetry provided that it happens near the TeV brane.
