Gauge Unification via Stable Brane Recombination

We study the transition between parallel and intersecting branes on a torus. Spontaneous symmetry breaking of nonabelian gauge symmetry is understood as brane separation, and a more general intermediate deformation is discussed. We argue that there exists supersymmetry preserving transition and we can always have parallel branes as a final state. The transition is interpreted due to dynamics of...

Dualities in 4D Theories with Product Gauge Groups from Brane Configurations

We study brane configurations which correspond to N=1 field theories in four dimensions. By inverting the order of the NS 5branes and D6-branes, a check on dualities in four dimensional theories can be made. We consider a brane configuration which yields electric/magnetic duality for gauge theories with SO(Nc1)× Sp(Nc2) product gauge group. We also discuss the possible extension to any alternat...

Meta - stable A n quiver gauge theories

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.

A Note on (Meta)stable Brane Configurations in MQCD

We examine the M-theory version of SQCD which is known as MQCD. In the IIA limit, this theory appears to have a supersymmetry-breaking brane configuration which corresponds to the meta-stable state of N = 1 SU(Nc) SQCD. However, the behavior at infinity of this non-supersymmetric brane construction differs from that of the supersymmetric ground state of MQCD. We interpret this to mean that it i...

Supersymmetric Models with Product Groups and Field Dependent Gauge Couplings

We study the dilaton-dependence of the effective action for N = 1, SU(N1)×SU(N2) models with one generation of vectorlike matter transforming in the fundamental of both groups. We treat in detail the confining and Coulomb phases of these models writing explicit expressions in many cases for the effective superpotential. We can do so for the Wilson superpotentials of the Coulomb phase when N2 = ...
