Gaugino Condensation with a Doubly Suppressed Gravitino Mass
arXiv:0804.3913 · doi:10.1103/PhysRevD.78.046002
Abstract
Supersymmetry breakdown via gaugino condensation in heterotic string theory can lead to models with a doubly suppressed gravitino mass. A TeV scale gravitino can emerge from a condensate as large as the grand unified scale. We analyze the properties of these models and discuss applications for particle physics and cosmology.
