Aspects of N = 2 supersymmetric gauge theories in three dimensions Original Research Article

We consider general aspects of N = 2 gauge theories in three dimensions, including their multiplet structure, anomalies and non-renormalization theorems. For U (1) gauge theories, we discuss the quantum corrections to the moduli space, and their relation to “mirror symmetries” of 3d N = 4 theories. Mirror symmetry is given an interpretation in terms of vortices. For SU (Nc) gauge groups with Nf fundamental flavors, we show that, depending on the number of flavors, there are quantum moduli spaces of vacua with various phenomena near the origin.
