Cosmological difficulties of N=1 supergravity models with sliding scales

We examine a class of N=1 supergravity models in which the supersymmetry breaking field is coupled to the inflation at the superpotential level and find through the perturbative solutions of the equations of motion that these models have a problematic cosmology. This occurs as the supersymmetry breaking field stores too much energy and dominates the energy density of the Universe at the present. (orig.)
