Metastable supersymmetry breaking without scales
We construct new examples of models of metastable D = 4 N = 1 supersymmetry breaking in which all scales are generated dynamically. Our models rely on Seiberg duality and on the ISS mechanism of supersymmetry breaking in massive SQCD. Some of the electric quark superfields arise as composites of a strongly coupled gauge sector. This allows us to start with a simple cubic superpotential and an a...
متن کاملSupersymmetry at Large Distance Scales
We propose that the UV/IR relation that underlies the AdS/CFT duality may provide a natural mechanism by which high energy supersymmetry can have large distance consequences. We motivate this idea via (a string realization of) the Randall-Sundrum scenario, in which the observable matter is localized on a matter brane separate from the Planck brane. As suggested via the holographic interpretatio...
متن کاملSupersymmetry Breaking at Low Energies
These lectures, given at the Cargese Summer school in 2008, provide an introduction to dynamical supersymmetry breaking and gauge mediation, with emphasis on the recent appreciation of the possible role of metastable supersymmetry breaking, and the evolving understanding of General Gauge Mediation. The underlying focus is on how supersymmetry might be realized at the Large Hadron Collider. 1 Su...
متن کاملPartial spontaneous breaking of two-dimensional supersymmetry
We construct low-energy Goldstone superfield actions describing various patterns of the partial spontaneous breakdown of two-dimensional N = (1, 1), N = (2, 0) and N = (2, 2) supersymmetries, with the main focus on the last case. These nonlinear actions admit a representation in the superspace of the unbroken supersymmetry as well as in a superspace of the full supersymmetry. The natural setup ...
متن کاملSoft Supersymmetry Breaking at Heavy Chiral Threshold
We discuss the structure of threshold corrections to soft supersymmetry-breaking parameters at the mass threshold of heavy chiral superfields. Nontrivial dependence on soft parameters of heavy matter fields originates from the ‘physical’ definition of the threshold scale, at which the general form of soft supersymmetry breaking is derived in the superfield coupling formalism. 1 E-mail: matsuura...
