Cosmology of supersymmetric models with low-energy gauge mediation
Cosmology of supersymmetric models with low-energy gauge mediation
We study the cosmology of supersymmetric models in which the supersymmetry-breaking effects are mediated by gauge interactions at about the ${10}^{5}$ GeV scale. We first point out that the gravitino is likely to overclose the Universe in this class of models. This requires an entropy production, which prefers a baryogenesis …
