Omega-Deformed Seiberg-Witten Effective Action from the M5-brane
arXiv:1304.3488 · doi:10.1016/j.physletb.2013.05.010
Abstract
We obtain the leading order corrections to the effective action of an M5-brane wrapping a Riemann surface in the eleven-dimensional supergravity Omega-background. The result can be identified with the first order epsilon-deformation of the Seiberg-Witten effective action of pure SU(2) gauge theory. We also comment on the second order corrections and the generalization to arbitrary gauge group and matter content.
