Goldstone-type superfields and partial spontaneous breaking of D=3, N=2 supersymmetry

TL;DR

This paper explores modified superfield constraints in three-dimensional N=2 supersymmetry, demonstrating partial breaking to N=1 through self-interactions and dual descriptions involving Goldstone superfields.

Contribution

It introduces a novel approach to partial supersymmetry breaking using modified superfield constraints with constant terms in D=3, N=2 models.

Findings

Partial spontaneous breaking of N=2 to N=1 supersymmetry is achieved.

The model includes a Fayet-Iliopoulos term facilitating breaking.

Dual descriptions via Goldstone chiral superfields are discussed.

Abstract

We consider the modified superfield constraints with constant terms for the D=3, N=2 Goldstone-Maxwell gauge multiplet which contains Goldstone fermions, real scalar and vector fields. The partial spontaneous breaking N=2 to N=1 is possible for the non-minimal self-interaction of this modified gauge superfield including the linear Fayet-Iliopoulos term. The dual description of the partial breaking in the model of the self-interacting Goldstone chiral superfield is also discussed.
