The $\mu$ and soft masses from the intermediate scale brane with   non-factorizable geometry
  The proton decay problem and the negative brane tension problem in the original Randall-Sundrum model can be resolved by interpreting the Planck scale brane as the visible sector brane. The hierarchy problem is resolved with supersymmetry, and the TeV scales for soft masses and $\mu$ in supersymmetric models are generated by the physics at the intermediate scale ($\sim 10^{11-13}$ GeV) brane.
