  The phase diagram of five-dimensional anisotropic gauge theories in a flat
background has been extensively explored during the last decade. Here, we
present novel results for the phase structure of the five-dimensional
anisotropic SU(2) model embedded in a warped background. The static potential
in the deconfining region of the phase diagram, close to the transition to the
layered phase, provides evidence of a Yukawa mass, suggesting that the system
is in a 4D Higgs-like phase. As no symmetry has been broken by the boundary
conditions, this phase appears to be due to the warp factor. Whether the system
is dimensionally reduced from a 5D phase to this 4D Higgs-like phase, which
would provide a mechanism for dimensional reduction via localization, remains
open.
