Braneworld scenarios with large and warped extra dimensions both assert among their accomplishments the resolution of the hierarchy problem. That is, both show that the Planck scale for gravitational interactions may flow from a natural, higher-dimensional scale of 1 TeV to an effective 4D scale of 1018 GeV, when gravity becomes bound to a 3-brane to act as an effective 4D 1/r2 force. However, both scenarios assume the existence of standard 4D matter on the brane with particle interactions at the scale 1 TeV. I instead treat matter and gravity symmetrically, as both originating in a higher dimensional field theory, then becoming bound to a 3-brane where they induce effective 4D field theories for gravity and matter. I track the flow of both Planck and particle scales, to see if a truly divergent flow arises to generate the observed 4D hierarchy. I examine this flow in extradimensional defect models — purely field theoretic models in which a defect forms in transverse extra dimensions and warps spacetime, so that the 3-brane at the defect core confines both gravity and matter into 4D effective theories.
