Attractions to radiation-like eras in superstring cosmologies
arXiv:1003.0840 · doi:10.1002/prop.201000041
Abstract
We review the cosmology induced by finite temperature and quantum effects on non-supersymmetric string models. We show the evolution is attracted to radiation-like solutions after the Hagedorn era and before the electroweak phase transition. This mechanism generates a hierarchy between the Planck mass and the supersymmetry breaking scale. A dynamical change of space-time dimension can take place.
