N = 2 gauge theories and quantum phases Jorge
The partition function of generalN = 2 supersymmetric SU(2) Yang-Mills theories on a four-sphere localizes to a matrix integral. We show that in the decompactification limit, and in a certain regime, the integral is dominated by a saddle point. When this takes effect, the free energy is exactly given in terms of the prepotential, F = −R2Re(4πiF), evaluated at the singularity of the Seiberg-Witt...
متن کامل2 00 5 Phases of N = 1 theories and factorization of Seiberg - Witten curves ∗
In this talk I review the structure of vacua of N = 2 theories broken down to N = 1 and it’s link with factorization of SeibergWitten curves. After an introduction to the structure of vacua in various supersymmetric gauge theories, I discuss the use of the exact factorization solution to identify different dual descriptions of the same physics and to count the number of connected domains in the...
متن کاملPhases of N = 1 Supersymmetric Gauge Theories with Flavors
We explore the phases of N = 1 supersymmetric U(N) gauge theories with fundamental matter that arise as deformations of N = 2 SQCD by the addition of a superpotential for the adjoint chiral multiplet. As the parameters in the superpotential are varied, the vacua of this theory sweep out various branches, which in some cases have multiple semiclassical limits. In such limits, we recover the vacu...
متن کاملPhases of N=1 supersymmetric chiral gauge theories
We analyze the phases of supersymmetric chiral gauge theories with an antisymmetric tensor and (anti)fundamental flavors, in the presence of a classically marginal superpotential deformation. Varying the number of flavors that appear in the superpotential reveals rich infrared chiral dynamics and novel dualities. The dualities are characterized by an infinite family of magnetic duals with arbit...
متن کاملPhases Of N = 2 Theories In 1 + 1 Dimensions With Boundary
We study B-type D-branes in linear sigma models with Abelian gauge groups. The most important finding is the grade restriction rule. It classifies representations of the gauge group on the Chan-Paton factor, which can be used to define a family of D-branes over a region of the Kähler moduli space that connects special points of different character. As an application, we find a precise, transpar...
