Title: The hierarchy problem and new extra dimension at a few TeV$^{-1}$

Abstract:
We propose a new mechanism with warped extra dimension to solve the hierarchy problem. It has the same KK spectrum as in the Arkani-Hamed-Dimopoulos-Dvali (ADD) model and recovers its phenomena. There is no hierarchy between the fundamental length and the size of the extra dimension. Two explicit realizations are constructed to give a warped description of the six-dimensional ADD model. Remarkably, the number $N$ of the extra dimensions in the generated description may be non-integral, which provides a new mechanism to escape the experimental constrains.
