High Energy Theory Seminar

Argyres-Douglas theories are four-dimensional N=2 SCFTs characterized by the existence of mutually non-local massless BPS states. The original examples of these theories were discovered almost twenty years ago at special points of the Coulomb branch in N=2 SQCD and are, in a sense I will make more precise, particularly simple examples of isolated conformal theories. However, due to the fact that Argyres-Douglas theories are inherently strongly coupled, many of their properties have remained mysterious. In the first part of this talk, I will explore a new set of dualities between these theories found by constructing conformal manifolds out of Argyres-Douglas building blocks. As I will explain, these dualities can shed some interesting light on the dynamics and spectra of these theories.
