چکیده
We study metastable dynamical breaking of supersymmetry in An quiver gauge theories. We present a general analysis and criteria for the perturbative existence of metastable vacua in quivers of any length. Different mechanisms of gauge mediation can be realized.

Dynamical SUSY Breaking at Meta-Stable Minima from D-branes at Obstructed Geometries
We study the existence of long-lived meta-stable supersymmetry breaking vacua in gauge theories with massless quarks, upon the addition of extra massive flavors. A simple realization is provided by a modified version of SQCD with Nf,0 < Nc massless flavors, Nf,1 massive flavors and additional singlet chiral fields. This theory has local meta-stable minima separated from a runaway behavior at in...
متن کاملLandscape of Supersymmetry Breaking Vacua in Geometrically Realized Gauge Theories
We study vacuum structure of N = 1 supersymmetric quiver gauge theories which can be realized geometrically by D brane probes wrapping cycles of local Calabi-Yau threefolds. In particular, we show that the A2 quiver theory with gauge group U(N1)× U(N2) with 1 2 N1 < N2 < 2 3 N1 has a regime with an infrared free description that is partially magnetic and partially electric. Using this dual desc...
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 کاملBPS Partition Functions for Quiver Gauge Theories: Counting Fermionic Operators
We discuss a general procedure to obtain 1/2 BPS partition functions for generic N = 1 quiver gauge theories. These functions count the gauge invariant operators (bosonic and fermionic), charged under all the global symmetries (mesonic and baryonic), in the chiral ring of a given quiver gauge theory. In particular we discuss the inclusion of the spinor degrees of freedom in the partition functi...
متن کاملComments on Quiver Gauge Theories and Matrix Models
Dijkgraaf and Vafa have conjectured the correspondences between topological string theories, N = 1 gauge theories and matrix models. By the use of this conjecture, we calculate the quantum deformations of Calabi-Yau threefolds with ADE singularities from ADE multi-matrix models. We obtain the effective superpotentials of the dual quiver gauge theories in terms of the geometric engineering for t...
