Metastable Vacua in Deformed N=2 Supersymmetric Models

TL;DR

This paper demonstrates that deformed N=2 supersymmetric Abelian models possess metastable vacua across various parameter ranges, which could have implications for realistic particle physics models.

Contribution

It identifies conditions under which deformed N=2 models have metastable vacua and explores their potential phenomenological relevance.

Findings

Metastable vacua exist in deformed N=2 Abelian models.

Nonsupersymmetric vacua are parametrically far from supersymmetric ones.

Retrofitting suggests possible semi-realistic phenomenology.

Abstract

We show that supersymmetric Abelian models that are obtained from deformations of those with ${\cal N}=2$ 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.
