ABSTRACT: In this talk, we discuss a gauge theory in a 5D warped space via
the dimensional deconstruction that a higher dimensional gauge
theory is constructed from a moose of 4D gauge groups. By the
AdS/CFT correspondence, a 5D warped gauge theory is dual to a
4D conformal field theory (CFT) with a global symmetry. As far as
physics of the gauge theory, we obtain the onetoone
correspondence between each component of a moose of gauge
groups and that of a CFT. We formulate a supersymmetric
extension of deconstruction and explore the framework of natural
supersymmetry in a 5D warped space ? the supersymmetric
RandallSundrum
model with the IRbrane
localized Higgs and bulk
fermions ? via the gauge moose. In this model, a supersymmetry
breaking source is located at the end of the moose corresponding to
the UV brane and the first two generations of squarks are decoupled.
With leftright
 gauge symmetries in the bulk of the moose, we
demonstrate realization of accidental or emergent supersymmetry of
the Higgs sector in comparison with the proposed “Moose/CFT
correspondence.”
