3d TQFT from 6d SCFT
Abstract
We study the sixdimensional (2, 0) superconformal field theory on S ^{1} × S ^{2} × M via compactification to five dimensions, where M is a threemanifold. Twisted along M, the fivedimensional theory has a half of supersymmetry on S ^{2}, the other half being broken by a superpotential. We show that in the limit where M is infinitely large, the twisted theory reduces to a threedimensional topological quantum field theory which is closely related to ChernSimons theory for the complexified gauge group.
