Description

We study the cosmological implictions of N=1 supergravity with the Polonyi potential. We find for typical values of the gravitino mass (102-103 GeV) the universe goes through a late period of reheating (i.e., from a temperature of about 10-7 MeV to 10-2 MeV). Any baryon-to-photon ratio is thus diluted by an unacceptable 15 orders of magnitude, with no hope of regeneration. (orig.)
