Cosmological Constraints on Perturbative Supersymmetry Breaking
S. A. Abel, S. Sarkar
Abstract
We discuss the cosmology of string models with perturbative supersymmetry breaking at a scale of O(TeV). Such models exhibit Kaluza-Klein like spectra and contain unstable massive gravitinos/gravitons. We find that considerations of primordial nucleosynthesis constrain the maximum temperature following inflation to be not much larger than the supersymmetry breaking scale. This imposes conflicting requirements on the scalar field driving inflation, making it rather difficult to construct a consistent cosmological history for such models.
