Moduli rolling to a natural MSSM with gravitino dark matter
  We propose the gravitino dark matter in the gravity mediated supersymmetry
breaking scenario. The mass hierarchies between the gravitino and other
superparticles can be achieved by the nontrivial K\"ahler metric of the
supersymmetry breaking field. As a concrete model, we consider the
five-dimensional supergravity model in which moduli are stabilized, and then
one of the moduli induces the slow-roll inflation. It is found that the relic
abundance of the gravitino and the Higgs boson mass reside in the allowed range
without a severe fine-tuning.
