Résumé |
Gauge theories in three dimensions can admit monopole operators in the potential.
Starting from an interacting gauge theory without monopole potential, if the
monopole term is relevant, there is an RG flow to the monopole-deformed theory
TM. Focusing on U(Nc) SQCD with Nf flavors and N = 2 supersymmetry, we show that
even when the monopole potential is irrelevant, the monopole-modified theory TM
can exist and enjoy Seiberg-like dualities. We provide a renormalizable,
three-dimensional, UV completion of TM and discuss its electric-magnetic dual
description. As an application, we find the N=2 3D gauge theory corresponding to
a system of D3-D5-NS5 branes containing a stack of coincident NS5 branes broken
in half by a D5 brane. This Abelian gauge theory is a quiver containing many
monopole terms in the superpotential and is mirror-dual of a standard gauge
theory. |
