Duality in Supersymmetric YangMills Theory
Abstract
These lectures provide an introduction to the behavior of stronglycoupled supersymmetric gauge theories. After a discussion of the effective Lagrangian in nonsupersymmetric and supersymmetric field theories, I analyze the qualitative behavior of the simplest illustrative models. These include supersymmetric QCD for $N_f < N_c$, in which the superpotential is generated nonperturbatively, N=2 SU(2) YangMills theory (the SeibergWitten model), in which the nonperturbative behavior of the effective coupling is described geometrically, and supersymmetric QCD for N_f large, in which the theory illustrates a nonAbelian generalization of electricmagnetic duality. [Lectures presented at the 1996 TASI Summer School, to appear in the proceedings.]
