An Elementary Proof of the NonRenormalization Theorem for the WessZumino Model
Abstract
Using the exact renormalization group (ERG) differential equation, we give an elementary proof of the nonrenormalization theorem for the WessZumino model. We introduce auxiliary fields to linearize the supersymmetry transformation, but we do not rely on the superfield techniques. We give sufficient background material on the Wilson action and the ERG formalism to make the paper selfcontained.
