This anomalous breaking arises because the correct perturbative expansion in the instanton sector is not supersymmetric. The attempt to construct a manifestly supersymmetric expansion generates infra-red divergences.LaTeX, 24 pages, 8 figures (uuencoded)High Energy Physics - TheoryHigh Energy Physics - LatticeHigh Energy Physics - PhenomenologyAnomalous Supersymmetry Breaking by Instantonstext
