Exactly marginal deformations of quiver gauge theories as seen from brane tilings

چکیده
We study the relation between exactly marginal deformations in a large class of N = 1 superconformal quiver gauge theories described by brane tilings and the degrees of freedom in the corresponding 5brane systems. We show with the help of NSVZ exact β functions that there are generically d − 1 complex exactly marginal deformations of a gauge theory, where d is the perimeter of the corresponding toric diagram. We identify d − 3 complex marginal deformations as deformations of the brane system and Wilson lines on it, and the other two, the diagonal gauge coupling and a β-like deformation, as background supergravity fields.

Brane Tilings and Their Applications
We review recent developments in the theory of brane tilings and four-dimensional N = 1 supersymmetric quiver gauge theories. This review consists of two parts. In part I, we describe foundations of brane tilings, emphasizing the physical interpretation of brane tilings as fivebrane systems. In part II, we discuss application of brane tilings to AdS/CFT correspondence and homological mirror sym...

We re-interpret the anomaly cancellation conditions for the gauge symmetries and the baryonic flavor symmetries in quiver gauge theories realized by the brane tilings from the viewpoint of flux conservation on branes. ∗ E-mail: [email protected]
متن کاملQuiver Chern-Simons theories and crystals
We consider N = 2 quiver Chern-Simons theories described by brane tilings, whose moduli spaces are toric Calabi-Yau 4-folds. Simple prescriptions to obtain toric data of the moduli space and a corresponding brane crystal from a brane tiling are proposed. ∗ E-mail: [email protected] † E-mail: [email protected]
متن کاملExplicit Analysis of Kahler Deformations in 4D N=1 Supersymmetric Quiver Theories
Starting from the N = 2 SYM4 quiver theory living on wrapped NiD5 branes around S 2 i spheres of deformed ADE fibered Calabi-Yau threefolds (CY3) and considering deformations using massive vector multiplets, we explicitly build a new class of N = 1 quiver gauge theories. In these models, the quiver gauge group ∏ i U (Ni) is spontaneously broken down to ∏ i SU (Ni) and Kahler deformations are sh...
متن کاملN = 2 Quiver Gauge Theories 5 3 Flux Deformation of IIB
Deformation of N = 2 quiver gauge theories by adjoint masses leads to fixed manifolds of N = 1 superconformal field theories. We elaborate on the role of the complex three– form flux in the IIB duals to these fixed point theories, primarily using field theory techniques. We study the moduli space at a fixed point and find that it is either the two (complex) dimensional ALE space or three–dimens...
