Abstract
We study globally supersymmetric theories on runaway backgrounds arising from scalar potentials with a slope characterized by a scale . We find that, under mild assumptions, there always exists a massive Goldstino in the low-energy effective theory. In the simplest models, the effective mass of such a fermion is of order or of order when a seesaw mechanism takes place, where is a scale that characterizes the masses of other heavy fermions.
