Findings

Existence of metastable vacua in the Wess-Zumino model with messengers

Parameter regions where metastable vacua are stable

Application to a renormalizable gauge mediation model

Abstract

We present a general scheme for finding or creating a metastable vacuum in supersymmetric theories. By using the formalism, we show that there is a parameter region where a metastable vacuum exists in the Wess-Zumino model coupled to messenger fields. This model serves as a perturbative renormalizable model of direct gauge mediation.
