Description
O'Raifeartaigh models with general R-charge assignments can have vacua where both
supersymmetry and R-symmetry are spontaneously broken. Most of these vacua are
metastable because the potential shows a runaway behaviour. We explain the relation
between runaway directions and R-symmetry, and we discuss the origin of metastability
in these models. Besides, we show models with global symmetries that can play the
role of hidden metastable SUSY-breaking sector in theories with gauge mediation or
direct mediation.
