Marginal Deformations from Branes
We study brane configurations for four dimensionalN=1 supersymmetric gauge theories with quartic superpotentials which flow in the infrared to manifolds of interacting superconformal fixed points. We enumerate finite N=2 theories, from which a large class of marginal N=1 theories descend. We give the brane descriptions of these theories in Type IIA and Type IIB string theory. The Type IIB descr...
متن کاملDeformations and D-branes
I discuss the relation of Hochschild cohomology to the physical states in the closed topological string. This allows a notion of deformation intrinsic to the derived category. I use this to identify deformations of a quiver gauge theory associated to a D-branes at a singularity with generalized deformations of the geometry of the resolution of the singularity. An explicit map is given from nonc...
متن کاملMarginal Deformations In the Open Bosonic String Field Theory for N D0-branes
In this short note we give an example of the exact solution of the open bosonic string field theory defined on the background of N coincided D0-branes. This solution leads to the change of the original background to the background where D0-branes are localised in general positions.
متن کاملLarge Marginal Deformations in String Field Theory
We use the level truncation scheme to obtain accurate descriptions of open bosonic string field configurations corresponding to large marginal deformations such as background Wilson lines. To do so, we solve for all fields as functions of the massless string field, and confirm that the effective potential of the massless field becomes increasingly flat as the level of approximation is increased...
متن کاملMarginal Deformations and 3-Algebra Structures
We study marginal deformations of superconformal Chern-Simons matter theories that are based on 3-algebras. For this, we introduce the notion of an associated 3-product, which captures very general gauge invariant deformations of the superpotentials of the BLG and ABJM models. We also consider conformal multi-trace deformations preserving N = 2 supersymmetry. We then use N = 2 supergraph techni...
