Supersymmetry breaking by fluxes
Abstract
Type II string theory and Mtheory admit flux configurations that break supersymmetry below the KaluzaKlein scale. These backgrounds play a central role in most models of the string landscape. I argue that the behavior of such backgrounds at weak coupling is generically a rolling solution, not a static spacetime. Quantum corrections to the spacetime potential are computed around this classical timedependent background. This is particularly important for nonperturbative corrections. This change in perspective offers an explanation for why there appear to be many effective field theory models that seemingly evade the known nogo theorems forbidding de Sitter spacetimes. This has interesting implications for type IIB string landscape models.
