(0,2) ADE Models From Four Dimensions

Abstract

Four dimensional N=1 supersymmetric gauge theories with unitary gauge groups and matter in the adjoint and fundamental representations give rise to a series of non-trivial fixed points with an ADE classification. Many of these models exhibit generalizations of Seiberg duality. Upon compactification on a two-torus with suitable background fields for global U(1) symmetries, they flow at long distances to two dimensional theories with (0,2) supersymmetry. We study these theories, focusing on the two dimensional analogs of the four dimensional dualities.
