Extended supersymmetric moduli space and a SUSY/non-SUSY duality Original Research Article

We study image supersymmetric image gauge theories coupled to an adjoint chiral field with superpotential. We consider the full supersymmetric moduli space of these theories obtained by adding all allowed chiral operators. These include higher-dimensional operators that introduce a field-dependence for the gauge coupling. We show how Feynman diagram/matrix model/string theoretic techniques can all be used to compute the IR glueball superpotential. Moreover, in the limit of turning off the superpotential, this leads to a deformation of image Seiberg–Witten theory. In the case where the superpotential drives the squared gauge coupling to a negative value, we find that supersymmetry is spontaneously broken, which can be viewed as a novel mechanism for breaking supersymmetry. We propose a new duality between a class of image supersymmetric image gauge theories with field-dependent gauge couplings and a class of image gauge theories where supersymmetry is softly broken by nonzero expectation values for auxiliary components of spurion superfields.
