Inflation in Gauge Mediation and Gravitino Dark Matter
  We present an inflationary scenario based on a phenomenologically viable
model with direct gauge mediation of low-scale supersymmetry breaking.
Inflation can occur in the supersymmetry-breaking hidden sector. Although the
reheating temperature from the inflaton decay is so high that the gravitino
problem seems to be severe, late time entropy production from the decay of the
pseudomoduli field associated with the supersymmetry breaking can dilute
gravitinos sufficiently. We show that gravitinos are also produced from the
pseudomoduli decay and there is a model parameter space where gravitinos can be
the dark matter in the present universe.
