Supersymmetric mass spectra for gravitino dark matter with a high reheating temperature
Supersymmetric theories with gravitino dark matter generally do not allow the high reheating temperature required by thermal leptogenesis without running afoul of relic abundance or big bang nucleosynthesis constraints. We discuss new examples of particular supersymmetric mass spectra that do satisfy these requirements. The main implication is the near degeneracy of the gluino with the other neutralinos in the spectrum.
