Deformations of the SUSY SU(5) Theory with an Antisymmetric Tensor

TL;DR

This paper explores deformations of an N=1 supersymmetric SU(5) gauge theory with an antisymmetric tensor, showing how certain modifications lead to dual theories that dynamically break supersymmetry, with specific analysis for the case n=2.

Contribution

It introduces extra singlet fields and superpotential terms to connect the original theory to known supersymmetry-breaking dual models.

Findings

Dual magnetic descriptions exist for the theory.

Adding superpotential terms leads to known supersymmetry-breaking gauge theories.

The n=2 case shows how to estimate lifting of pseudo-flat directions.

Abstract

The N=1 supersymmetric gauge SU(5) theory with one antisymmetric tensor, n+3 fundamentals and n+4 antifundamentals has dual magnetic descriptions in the infrared. By introducing extra singlet fields and tree level superpotential terms to the electric SU(5) theories, we are able to make the dual theories flow to the known SU(n)xSU(2) gauge theories which break supersymmetry dynamically. In the n=2 case, the lifting of the pseudo-flat direction is estimated by using dual operator mappings.
