Abstract We point out a connection between R-symmetry and supersymmetry breaking. We show that the existence of an R-symmetry is a necessary condition for supersymmetry breaking and a spontaneously broken R-symmetry is a sufficient condition provided two conditions are satisfied. These conditions are: genericity, i.e. the effective lagrangian is a generic lagrangian consistent with the symmetries of the theory (no fine tuning), and calculability, i.e. the low-energy theory can be described by a… Expand
