N = 2 superconformal field theory with ADE global symmetry on a D3-brane probe

Abstract

We study mass deformations of N = 2 superconformal field theories with ADE global symmetries on a D3-brane. The N = 2 Seiberg-Witten curves with ADE symmetries are determined by the Type IIB 7-brane backgrounds which are probed by a D3-brane. The Seiberg-Witten differentials λ for these ADE theories are constructed. We show that the poles of λ with residues are located on the global sections of the bundle in an elliptic fibration. It is then clearly seen how the residues transform in an irreducible representation of the ADE groups. The explicit form of λ depends on the choice of a representation of the residues. Nevertheless the physics results are identical irrespective of the representation of λ. This is considered as the global symmetry version of the universality found in N = 2 Yang-Mills theory with local ADE gauge symmetries. *

1-form symmetries of 4d N=2 class S theories

“…where the resolutions parametrized for the ALE-fiber are encoded in a Higgs field ϕ. The connection is made through the Higgs bundle, [45,46]. The Higgs field ϕ is a meromorphic 1-form valued in the respective ADE Lie algebra g. We consider the 6d (2,0) theory of type ADE on C g,n , with the standard topological twist that retains N = 2 supersymmetry in 4d, i.e.…”

$ \mathcal{N} = 1 $ SCFTs from brane monodromy

“…D3-brane probes of F-theory singularities have been considered in various works, for example [8][9][10][11][12][13][14]. In many cases of interest, the probe theory becomes an interacting superconformal field theory (SCFT).…”
