| Abstract: |
Part 1: I will review basic facts about magnetic monopoles and how they allow us to understand confinement in supersymmetric gauge theories. Part 2: I will revisit the study of singular points in N = 2 SQCD with classical gauge groups. Generalizing a technique proposed recently by Gaiotto, Seiberg and Tachikawa we find that the low-energy physics at the maximally singular points involves two superconformal sectors coupled to an infrared free SU(2) gauge group. Some of these points play a key role in understanding the properties of the theory when one softly breaks extended supersymmetry to N =1, adding a mass term for the chiral multiplet in the adjoint representation. I will discuss how confinement and chiral symmetry breaking are realized in these models. |
