| heal.abstract | We elaborate further on a recently proposed scenario for generating a mass hierarchy through quantum fluctuations of a single D3-brane, which represents our world embedded in a bulk five-dimensional space-time. In this scenario, the quantum fluctuations of the D3-brane world in the bulk direction, quantified to leading order via a "recoil" world-sheet lograrithmic conformal field theory approach, result in the dynamical appearance of a supersymmetry breaking (obstruction) scale alpha. This may be naturally taken to be at the TeV range, in order to provide a solution to the conventional gauge-hierarchy problem. The bulk spatial direction is characterized by the dynamical appearance of a horizon located at +/- 1/alpha, inside which the positive energy conditions for the existence of stable matter are satisfied. To ensure the correct value of the four-dimensional Planck mass, the bulk string scale M-s is naturally found to lie at an intermediate energy scale of 10(14) GeV. As an exclusive feature of the D3-brane quantum fluctuations ("recoil") we iind that, for any given M-5, there is a discrete mass spectrum for four-dimensional Kaluza-Klein (KK) modes of bulk graviton and/or scalar fields. KK modes with masses 0 less than or equal tom<<root>2 alpha<<M-s are found to have wave functions peaked, and hence localized, on the D3-brane at z=0. | en |
