D-branes and fractional instantons on a twisted four torus: the moduli space as an N=2 supersymmetric Higgs branch

Erich Poppitz

Fractional instantons on twisted four-tori have moduli spaces that locally match the Higgs branch of an N=2 supersymmetric theory.

Claims

C1strongest claim

locally, the moduli space is identified with the Higgs branch of an N=2 supersymmetric theory. This parameterization of the moduli space is equivalent to one recently found in field theory, but is obtained with significantly less effort and has manifest hyper-Kähler structure.

C2weakest assumption

That the constructed wrapped intersecting brane configurations are dual to general constant field strength instanton backgrounds in the gauge theory on the twisted torus.

C3one line summary

The local moduli space of self-dual fractional instantons (Q = r/N) on a twisted four-torus is the Higgs branch of an N=2 supersymmetric theory, obtained via wrapped intersecting D-brane configurations.
