Description
We summarize the recent progress in the gauge theory with spontaneously broken N=2 supersymmetry. We consider the low energy processes described by the N=2 supercurrent on its partially (to N=1) and spontaneously broken tree vacuum and the attendant Nambu-Goldstone fermion (NGF), which the presence of the electric and magnetic Fayet-Iliopoulos (FI) terms is responsible for. We show suppression of amplitudes decaying into the NGF as its momentum becomes small.
By invoking mechanism which simulates that of the BCS/NJL in superconductivity/chiral symmetry, we consider the possibility that the N=1 supersymmetry is further broken to N=0.
