Non Supersymmetric Vacua and the D-flatness Condition

چکیده

Some N = 1 gauge theories, including SQED and NF = 1 SQCD, have the property that, for arbitrary superpotentials, all stationary points of the potential V = F +D are D−flat. For others, stationary points of V are complex gauge transformations of D−flat configurations. As an implication, the technique to parametrize the moduli space of supersymmetric vacua in terms of a set of basic holomorphic G invariants can be extended to non-supersymmetric vacua. A similar situation is found in non-gauge theories with a compact global symmetry group. Typeset using REVTEX Fundación Antorchas postdoctoral fellow.

Classification of Flat Directions in Perturbative Heterotic Superstring Vacua with Anomalous U ( 1 )

We develop techniques to classify Dand F -flat directions for N = 1 supersymmetric string vacua of the perturbative heterotic string theory, which possess an anomalous U(1) gauge group at the tree level. Genus-one corrections generate a Fayet-Iliopoulos term for the D-term of U(1)A, which is canceled by non-zero vacuum expectation values (VEVs) of certain massless multiplets in such a way that ...

A World-Volume Perspective on the Recombination of Intersecting Branes

We study brane recombination for supersymmetric configurations of intersecting branes in terms of the world-volume field theory. This field theory contains an impurity, corresponding to the degrees of freedom localized at the intersection. The Higgs branch, on which the impurity fields condense, consists of vacua for which the intersection is deformed into a smooth calibrated manifold. We show ...

Varieties of vacua in classical supersymmetric gauge theories.

We give a simple description of the classical moduli space of vacua for supersymmetric gauge theories with or without a superpotential. The key ingredient in our analysis is the observation that the lagrangian is invariant under the action of the complexified gauge group G. From this point of view the usual D-flatness conditions are an artifact of Wess–Zumino gauge. By using a gauge that preser...

Nonlinear N = 2 Supersymmetry , Effective Actions and Moduli Stabilization

Nonlinear supersymmetry is used to compute the general form of the effective D-brane action in type I string theory compactified to four dimensions in the presence of internal magnetic fields. In particular, the scalar potential receives three contributions: (1) a nonlinear part of the D-auxiliary component, associated to the Dirac-Born-Infeld action; (2) a Fayet-Iliopoulos (FI) D-term with a m...

Mirrorfolds with K3 Fibrations

We study a class of non-geometric string vacua realized as completely soluble superconformal field theory (SCFT). These models are defined as ‘interpolating orbifolds’ of K3×S1 by the mirror transformation acting on the K3 fiber combined with the half-shift on the S1-base. They are variants of the T-folds, the interpolating orbifolds by T-duality transformations, and thus may be called ‘mirrorf...
