Description
After briefly reviewing the insights of Seiberg and Witten (1994) which provide a low-energy description of N = 2 SUSY theories featuring massless monopoles, we investigate N = 1 supersymmetric gauge theories where monopole condensation triggers supersymmetry breaking in a metastable vacuum. The low-energy effective theory is an O’Raifeartaigh-like model of the kind investigated recently by Shih where the R-symmetry can be spontaneously broken.
