The paper explores the possibility of having the Standard Model (SM) fields living in a slice of anti-de Sitter (AdS) space, rather than being confined to a brane. This approach aims to solve the hierarchy problem by generating the electroweak scale through a "warp" factor in the induced metric on the brane. The authors analyze the behavior of fermions, gauge bosons, and scalars in this geometry and their implications for electroweak physics. They also consider the possibility of supersymmetry in the bulk and derive the conditions for its realization, including the mass spectrum. The paper proposes a model where the warp factor generates a small supersymmetry-breaking scale, with gauge interactions mediating the breaking to the scalar sector. The phenomenological consequences of having SM fields in the bulk are discussed, including the explanation of the fermion mass hierarchy and the suppression of higher-dimensional operators. The inclusion of supersymmetry allows for the delocalization of the Higgs field and fermions, potentially suppressing proton decay while allowing for the generation of fermion masses. The paper concludes by discussing the implications for phenomenology, such as the suppression of higher-dimensional operators and the potential for testing GUT or quantum gravity theories at the TeV scale.The paper explores the possibility of having the Standard Model (SM) fields living in a slice of anti-de Sitter (AdS) space, rather than being confined to a brane.
