Metastable Vacua in Deformed N=2 Supersymmetric Models
arXiv:0906.2127 · doi:10.1142/S0217751X11051512
Abstract
We show that supersymmetric Abelian models that are obtained from deformations of those with supersymmetry also contain metastable vacua for a wide range of parameters. The deformations we consider are combinations of masses for charged and singlet fields, a singlet F--term and an anomalous D--term. We find that, in all cases, the nonsupersymmetric vacua are parametrically far from the supersymmetric ones and therefore metastable. Using retrofitting, we show that these metastable vacua may lead to semi--realistic phenomenology.
