Description

Instanton effects on supersymmetry breaking in the O(3) non-linear sigma-model are investigated in detail in the semiclassical approximation. The conclusion is that instantons cannot break the supersymmetry neither spontaneously nor explicitly for any O(3)-invariant operator under consideration. Examples are however given of operators that belong to an infinite-dimensional representation of O(3) and break the supersymmetric Ward identities explicitly via instanton effects, and such examples are connected to fermionic zero-mode condensates.
