Abstract
We recently proposed a solution to the hierarchy problem not relying on low-energy supersymmetry or technicolor. Instead, the problem is nullified by bringing quantum gravity down to the TeV scale. This is accomplished by the presence of n ≥ 2 new dimensions of sub-millimeter size, with the SM fields localised on a 3-brane in the higher dimensional space. In this paper we systematically study the experimental viability of this scenario. Constraints arise both from strong quantum gravitational effects at the TeV scale, and more importantly from the production of massless higher dimensional gravitons with TeV suppressed couplings. Theories with n> 2 are safe due mainly to the infrared softness of higher dimensional gravity. For n = 2, the six dimensional Planck scale must be pushed above ∼ 30 TeV to avoid cooling SN1987A and distortions of the diffuse photon background. Nevertheless, the particular implementation of our
