In order to discriminate between inflatino and gravitino production, the situation in which the two sectors communicate only gravitationally was studied. The spectrum of the gravitinos produced at preheating was computed. It was concluded that what in the previous works was believed to be gravitino overproduction is actually inflatino production.

Abstract
In order to discriminate between inflatino and gravitino production, the situation in which the two sectors communicate only gravitationally was studied. The spectrum of the gravitinos produced at preheating was computed. It was concluded that what in the previous works was believed to be gravitino overproduction is actually inflatino production.
