dynamical susy breaking in meta stable vacua
Journal of High Energy Physics, 2006Co-Authors: Kenneth Intriligator, Nathan Seiberg, David ShihAbstract:Dynamical Supersymmetry breaking in a long-lived meta-stable vacuum is a phenomenologically viable possibility. This relatively unexplored avenue leads to many new models of dynamical Supersymmetry breaking. Here, we present a surprisingly simple class of models with meta-stable dynamical Supersymmetry breaking: = 1 supersymmetric QCD, with massive flavors. Though these theories are strongly coupled, we definitively demonstrate the existence of meta-stable vacua by using the free-magnetic dual. Model building challenges, such as large flavor symmetries and the absence of an R-symmetry, are easily accommodated in these theories. Their simplicity also suggests that broken Supersymmetry is generic in supersymmetric field theory and in the landscape of string vacua.

complete superspace classification of three dimensional chern simons matter theories coupled to supergravity
Journal of High Energy Physics, 2018Co-Authors: Frederik Lauf, Ivo SachsAbstract:For extended $$ \mathcal{N} $$ ≤ 8 Supersymmetry we classify all possible gauge groups for a scalar multiplet allowed by the algebras of global and local Supersymmetry in three dimensions. A detailed discussion of Supersymmetry enhancement is included. For the corresponding topologically massive gravity with negative cosmological constant the mass of the graviton is determined algebraically as a function of $$ \mathcal{N} $$ and the possible gauge couplings.

the supergravity dual of a theory with dynamical Supersymmetry breaking
Journal of High Energy Physics, 2001Co-Authors: Juan Maldacena, Horatiu NastaseAbstract:We study the large-N limit of a little string theory that reduces in the IR to U(N) = 1 supersymmetric Yang-Mills with Chern-Simons coupling k. Witten has shown that this field theory preserves Supersymmetry if k ≥ N/2 and he conjectured that it breaks Supersymmetry if k < N/2. We find a non-singular solution that describes the k = N/2 case, which is confining. We argue that increasing k corresponds to adding branes to this solution, in a way that preserves Supersymmetry, while decreasing k corresponds to adding anti-branes, and therefore breaking Supersymmetry.

meta stable dynamical Supersymmetry breaking near points of enhanced symmetry
Journal of High Energy Physics, 2007Co-Authors: Rouven Essig, Kuver Sinha, Gonzalo TorrobaAbstract:We construct a model with long-lived metastable vacua in which all the relevant parameters, including the Supersymmetry breaking scale, are generated dynamically by dimensional transmutation. Our model consists of two sectors coupled by a singlet and combines dynamical Supersymmetry breaking with an O'Raifeartaigh mechanism in terms of confined variables. The metastable vacua appear along a pseudo-runaway direction near a point of enhanced symmetry as a result of a balance between non-perturbative and perturbative quantum effects. We show that metastable Supersymmetry breaking is a rather generic feature near certain enhanced symmetry points of gauge theory moduli spaces.
