New Models of Gauge Mediated Dynamical Supersymmetry Breaking

Abstract

We propose a simple class of nonrenormalizable models of gauge mediated dynamical supersymmetry breaking. The models do not have gauge singlet fields. The Standard Model gauge group is embedded in the global symmetry of the SUSY breaking sector. At the renormalizable level the models possess a set of classical flat directions. Only one of those flat directions is unlifted by quantum effects, and requires nonrenormalizable term to stabilize the potential for the corresponding modulus. Large vacuum expectation value of this modulus at the minimum of the potential generates mass terms for the messenger fields. There are no light messengers, thus this class of models evades difficulties encountered in earlier constructions using nonrenormalizable models.
