Calculable Dynamical Supersymmetry Breaking on Deformed Moduli Spaces

TL;DR

This paper demonstrates that in certain models of dynamical supersymmetry breaking, the low-energy effective theory simplifies to an O'Raifeartaigh model, allowing for exact calculations of pseudo-flat direction masses.

Contribution

It shows that models with conflicting superpotential extremization and quantum constraints reduce to calculable O'Raifeartaigh models near the origin.

Findings

Mass-squared of pseudo-flat directions is calculable.

Stable minimum at the origin with unbroken U(1)_R symmetry.

Applicable to SU(N) and Sp(2N) gauge groups with/without global symmetries.

Abstract

We consider models of dynamical supersymmetry breaking in which the extremization of a tree-level superpotential conflicts with a quantum constraint. We show that in such models the low-energy effective theory near the origin of moduli space is an O'Raifeartaigh model, and the sign of the mass-squared for the pseudo-flat direction at the origin is calculable. We analyze vector-like models with gauge groups SU(N) and Sp(2N) with and without global symmetries. In all cases there is a stable minimum at the origin with an unbroken U(1)_R symmetry.
