Query: The Hierarchy Problem and New Warped Extra Dimension   In this paper, we propose a new mechanism with warped extra dimension to
solve the hierarchy problem, which is parallel to the Randall-Sundrum (RS)
brane scenario. Different from the RS scenario, the fundamental scale is TeV
scale and the four-dimensional Planck scale is generated from the exponential
warped extra dimension at size of a few TeV$^{-1}$. The experimental
consequences of this scenario are very different from that of the RS scenario.
In the explicit realization in the nonlocal gravity theory, there is a tower of
spin-2 excitations with mass gap $10^{-4}\text{eV}$ and they are coupled with
the gravitational scale to the standard model particles. We further discuss the
possible generalizations in other modified gravity theories. The experimental
consequences are similar to $(4+N)$-dimensional large extra dimension but $N$
can be a non-integer, which satisfies the experimental constraints more easily
than the integer large extra dimension model.
