Dual N=2 SUSY breaking

We discuss spontaneous supersymmetry breaking in N = 2 globally supersymmetric theories describing a system of abelian Vector multiplets. The most general form of the action admits, in addition to the usual Fayet-Iliopoulos term, a magnetic Fayet-Iliopoulos term for the auxiliary components of dual vector multiplets. In a generic case, this leads to a spontaneous breakdown of one of the two supersymmetries. In some cases however, dyon condensation restores N = 2 SUSY vacuum. This talk is based on the work done in collaboration with H. Partouche, [1].
