Abstract
A perturbative nonrenormalization theorem is presented that applies to general supersymmetric theories, including nonrenormalizable theories in which the integrand of the action is an arbitrary gauge-invariant function of the chiral superfields and gauge field-strength superfields , and the integrand is restricted only by gauge invariance. In the Wilsonian Lagrangian, is nonrenormalized except for the one-loop renormalization of the gauge coupling parameter, and Fayet-Iliopoulos terms can be renormalized only by one-loop graphs. One consequence of this theorem is that in nonrenormalizable as well as renormalizable theories, in the absence of Fayet-Iliopoulos terms supersymmetry will be unbroken to all orders, if the bare superpotential has a stationary point.
