Supersymmetry breaking at the end of a cascade of Seiberg dualities

TL;DR

This paper investigates the infrared behavior of a specific non-conformal quiver gauge theory derived from D3 branes, revealing that supersymmetry is dynamically broken at the cascade's end.

Contribution

It provides a detailed analysis of supersymmetry breaking in a complex quiver theory associated with a Sasaki-Einstein manifold, extending understanding of IR dynamics in such models.

Findings

Supersymmetry is dynamically broken at the end of the cascade.

The study connects geometric properties of the cone over del Pezzo surfaces with gauge theory dynamics.

The analysis enhances understanding of IR phenomena in non-conformal quiver theories.

Abstract

We study the IR dynamics of the cascading non-conformal quiver theory on N regular and M fractional D3 branes at the tip of the complex cone over the first del Pezzo surface. The horizon of this cone is the irregular Sasaki-Einstein manifold Y^{2,1}. Our analysis shows that at the end of the cascade supersymmetry is dynamically broken.
