Dynamical supersymmetry breaking in theories without Lagrangians

Year: 2013

Type: article

Abstract: We demonstrate that the supersymmetry can be dynamically broken even in theories without a Lagrangian. The example we study is the four-dimensional $\mathrm{SU}(N)$ gauge theory coupled to a strongly coupled superconformal theory, called ${T}_{N}$, which does not have a Lagrangian description at present. Such a theory without Lagrangians can be analyzed due to the supersymmetry and duality. The model is a direct generalization of the model of supersymmetry breaking on deformed moduli space in supersymmetric QCD with an SU(2) gauge group.
