Can Pions ``Smell'' 4D, N = 1 Supersymmetry?

Abstract

We show how the usual chiral perturbation theory description of phenomenological pion physics admits an interpretation as a low-energy string-like model associated with QCD. By naive and straightforward generalization within the context of a new class of supersymmetrical models, it is shown that this string-like structure admits a 4D, N = 1 supersymmetrical extension. The presence of a WZNW term in the model implies modifications of certain higher order processes involving the ordinary SU(3) pion octet.
