title = "Gravitino overproduction in inflaton decay",
abstract = "We show that the gravitino-overproduction problem is prevalent among inflation models in supergravity. An inflaton field generically acquires (effective) non-vanishing auxiliary field, if the Kahler potential is non-minimal. The inflaton field then decays into a pair of the gravitinos, thereby constraining many of the inflation models severely especially in the case of the gravity-mediated SUSY breaking.",
