Dynamical Supersymmetry Breaking without Messenger Gauge Interactions
We investigate low-energy models of supersymmetry (SUSY) breaking by means of vector-like gauge theories for dynamical SUSY breaking. It is not necessary to introduce messenger gauge interactions utilized so far to mediate the SUSY breaking to the standard-model sector, which reduces complication in the model building. We also consider various other ways of SUSY-breaking transmission.
متن کاملDynamical GUT breaking and μ-term driven supersymmetry breaking
Models for dynamical breaking of supersymmetric grand unified theories are presented. The doublet-triplet splitting problem is absent since the Higgs doublet superfields can be identified with the massless mesons of the strong gauge group whereas there are no massless states corresponding to the colored Higgs fields. Various strong gauge groups SU(Nc), Sp(Nc) and SO(Nc) are examined. In a model...
متن کاملDynamical Supersymmetry Breaking
We review mechanisms of dynamical supersymmetry breaking. Several observations that narrow the search for possible models of dynamical supersymmetry breaking are summarized. These observations include the necessary and sufficient conditions for supersymmetry breaking. The two conditions are based on non-rigorous arguments, and we show examples where they are too restrictive. Dynamical effects p...
متن کاملDynamical Supersymmetry Breaking
The ratio of the weak scale to the Planck scale, mW /mPl ∼ 10 , suggests that it should have a dynamical origin. Had this ratio been, e.g., ∼ 10 we would have suspected that the weak scale is a perturbative effect. In fact this ratio is of the right size for a nonperturbative effect in field theory. Had it been extremely small, e.g. ∼ 10 10 or so, we would have to look for some really exotic, u...
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...
