Boosting Away Singularities from Conformal String Backgrounds

High Energy Physics - Theory 2009-10-22 v1

Abstract

Generalizing our previous work, we show how O(d,d)O(d,d) transformations can be used to "boost away" in new dimensions the physical singularities that occur generically in cosmological and/or black-hole string backgrounds. As an example, we show how a recent model by Nappi and Witten can be made singularity-free via O(3,3)O(3,3) boosts involving a fifth dimension.
