Anomalous Supersymmetry Breaking by Instantons
A. Casher, V. Elkonin, Y. Shamir
Abstract
We show that instantons violate a supersymmetric identity in a classically supersymmetric Higgs model with no massless fermions. 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.
