N=2 Quiver Gauge Model and Partial Supersymmetry Breaking

TL;DR

This paper constructs an N=2 affine A_n quiver gauge model with non-canonical kinetic terms, demonstrating spontaneous partial supersymmetry breaking to N=1 and exploring its relation to the Klebanov-Witten fixed point.

Contribution

It introduces a novel N=2 affine A_n quiver gauge model with electric and magnetic FI terms, showing spontaneous N=2 to N=1 supersymmetry breaking and connections to known fixed points.

Findings

N=2 supersymmetry is spontaneously broken to N=1.

The model includes electric and magnetic FI terms.

Affine A_1 quiver model relates to the Klebanov-Witten fixed point.

Abstract

We construct an action of N=2 affine $A_n$ quiver gauge model having non-canonical kinetic terms and equipped with electric and magnetic FI terms. N=2 supersymmetry is shown to be broken to N=1 spontaneously and N=1 multiplets realized on the vacua are given. We also mention the models with different gauge groups. It is argued that the affine $A_1$ quiver gauge model provides a dynamical realization to approach the Klebanov-Witten N=1 fixed point.
