question
What generates the weak-Planck hierarchy - is the fundamental scale of quantum gravity near a TeV?
statement
Spacetime contains one small extra dimension forming a slice of AdS5 bounded by two 3-branes (SM fields on the visible brane); the exponential warp factor e^(-k rc pi) with krc ~ 50 redshifts all visible-brane mass parameters from near-Planckian inputs to the weak scale, solving the hierarchy problem without a large compactification volume.

Abstract; §1-4

The second principal TeV-gravity model family (alongside ADD). Unlike ADD it needs only one extra dimension, whose size is only ~50 fundamental lengths; equivalently, from the visible-brane viewpoint the effective strong-gravity scale is ~TeV because of the small overlap of the graviton wave function with our brane, while the fundamental 5D scales all sit near M_Pl.
