Theories with gauge-mediated supersymmetry breaking provide an interesting alternative to
the scenario in which the soft terms of the low-energy fields are induced by gravity. These …

We study the vacuum structure and don spectrum of N= 2 supersymmetric gauge theory in
four dimensions, with gauge group SU (2). The theory turns out to have remarkably rich and …

We study four dimensional N= 2 supersymmetric gauge theories with matter multiplets. For
all such models for which the gauge group is SU (2), we derive the exact metric on the …

We demonstrate electric-magnetic duality in N= 1 supersymmetric non-Abelian gauge
theories in four dimensions by presenting two different gauge theories (different gauge …

In these notes we attempt to give a pedagogical introduction to the work of Seiberg and
Witten on S‐duality and the exact results of N= 2 supersymmetric guage theories with and …

It is pointed out that string-loop modifications of the low-energy matter couplings of the
dilation may provide a mechanism for fixing the vacuum expectation value of a massless …

Just as parallel threebranes on a smooth manifold are related to string theory on AdS 5× S 5,
parallel threebranes near a conical singularity are related to string theory on AdS5× X5, for a …

Recently, it has become clear that certain aspects of four dimensional supersymmetric field
theories can be analyzed exactly, providing a laboratory for the analysis of the dynamics of …

In these lecture notes we first assemble the basic ingredients of supersymmetric gauge
theories (particularly N= 4 super-Yang-Mills theory), supergravity, and superstring theory …

We show that manifolds of fixed points, which are generated by exactly marginal operators,
are common in N= 1 supersymmetric gauge theory. We present a unified and simple …
