Semi-Direct Gauge Mediation with the 4-1 Model
We analyze a model of Semi-Direct Gauge Mediation in which the hidden sector is the 4-1 model and the messenger fields are charged under the U(1) gauge group. At tree level, the SUSY-breaking F-terms induce D-terms from which SUSY-split messenger masses arise. We calculate these masses by three complementary methods. Additionally, we compute the one-loop corrections to the masses. We consider t...
متن کاملA Model of Direct Gauge Mediation
We present a simple model of gauge mediation (GM) which does not have a messenger sector or gauge singlet fields. The standard model gauge groups couple directly to the sector which breaks supersymmetry dynamically. This is the first phenomenologically viable example of this type in the literature. Despite the direct coupling, the model can preserve perturbative gauge unification. This is achie...
متن کاملNew Mechanisms of Dynamical Supersymmetry Breaking and Direct Gauge Mediation
We construct supersymmetric gauge theories with new mechanisms of dynamical supersymmetry breaking. The models have flat directions at the classical level, and different mechanisms lift these flat directions in different regions of the classical moduli space. In one branch of the moduli space, supersymmetry is broken by confinement in a novel manner. The models contain only dimensionless coupli...
متن کاملModuli Problem in a Supersymmetric Model with Direct Gauge Mediation
Recently, an interesting class of the direct gauge mediation supersymmetry (SUSY) breaking models are proposed, in which the minimum of the potential of the SUSY breaking field is determined by the inverted hierarchy mechanism. We consider their cosmological implications. In this class of models, SUSY breaking field has a very flat potential, which may have a cosmological importance. Assuming t...
متن کاملAn Extension for Direct Gauge Mediation of Metastable Supersymmetry Breaking
We study the direct mediation of metastable supersymmetry breaking by a Φ (Φ is the meson field) deformation to the ISS model and extend it by splitting Φ into two parts and gauging the flavor symmetry. We find that with such an extension the enough longlived metastable vacua can be obtained and the proper gaugino masses can be generated. Further, this allows for constructing a kind of models w...
