Abstract
Nonrenormalizable couplings in supergravity-coupled supersymmetric the ories can give rise to power-law divergences that destabilize the weak -scale hierarchy. For the case of the standard-model gauge group, the problem can arise in theories with SU(3) x SU(2) x U(1) gauge-singlet chiral superfields. The minimal supersymmetric standard model is free from such destabilizing divergences.
