TL;DR
This paper reviews the phenomenon of partial spontaneous supersymmetry breaking in N=2 gauge theories, explaining how it circumvents previous no-go theorems and exploring implications for theories with matter and gauging.
Contribution
It provides a detailed review of partial supersymmetry breaking in N=2 theories and discusses the extension to matter-coupled cases, highlighting the role of gauging.
Findings
Partial spontaneous breaking of N=2 supersymmetry demonstrated.
Standard no-go theorem is evaded in specific models.
Gauging prevents the existence of magnetic Fayet-Iliopoulos terms.
Abstract
We review in detail the recently discovered phenomenon of partial spontaneous breaking of supersymmetry in the case of a N=2 pure gauge U(1) theory, and recall how the standard lore no-go theorem is evaded. We discuss the extension of this mechanism to theories with charged matter, and surprisingly find that the gauging forbids the existence of a magnetic Fayet-Iliopoulos term.
