Abstract
We formulate a supersymmetric model by using a chiral Lagrange superfield to impose the condition on a field theory model that the classical equations of motions are satisfied. This we show results in all radiative effects being restricted to one-loop order, making it possible to find exact renormalization group functions. We then consider the consequences of a local gauge symmetry and examine two models that have such a symmetry.
