N = 2 SU quiver with USP ends or SU ends with antisymmetric matter

Abstract

We consider the four dimensional scale invariant N = 2SU quiver gauge theories with USp(2N) ends or SU(2N) ends with antisymmetric matter representations. We argue that these theories are realized as six dimensional A 2N-1 (0,2) theories compactified on spheres with punctures. With this realization, we can study various strongly coupled cusps in moduli space and find the S-dual theories. We find a class of isolated superconformal field theories with only odd dimensional operators D(φ) 3 and superconformal field theories with only even dimensional operators D(φ) 4. © SISSA 2009.
