A superfield constraint for N=2 --> N=0 breaking

TL;DR

This paper introduces a cubic holomorphic constraint that fully breaks N=2 supersymmetry in a vector multiplet, resulting in a non-linear low-energy Lagrangian with a vector and goldstini, extending the N=2 Volkov-Akulov model.

Contribution

It presents a novel cubic holomorphic constraint for complete N=2 to N=0 supersymmetry breaking and derives its microscopic origin.

Findings

Identified a cubic holomorphic constraint for N=2 to N=0 breaking.

Derived a non-linear Lagrangian with a vector and goldstini.

Generalized the N=2 Volkov-Akulov model.

Abstract

We identify a cubic holomorphic constraint that subtends the total breaking of N=2 supersymmetry in a vector multiplet and exhibit its microscopic origin. The new constraint leaves behind, at low energies, a vector and the two goldstini, in a non-linear Lagrangian that generalizes the N=2 Volkov-Akulov model.
