Probing Naked Singularities in Non-supersymmetric String Vacua

High Energy Physics - Theory 2010-02-03 v2

Abstract

We present a detailed analysis of non-supersymmetric spacetime varying string vacua which can lead to an exponential hierarchy between the electroweak and the gravitational scales. In particular, we identify a limit in which these vacua can be interpreted as supersymmetric vacua of F-theory. Furthermore, we study the properties of these solutions as seen by D7D7-brane probes and establish a non-supersymmetric analogue of the enhancon mechanism.
