Complex linear superfield as a model for Goldstino

TL;DR

This paper introduces a new Goldstino model based on a constrained complex linear superfield, comparing it to existing models and discussing its couplings to matter and supergravity.

Contribution

It presents a novel Goldstino model using a constrained complex linear superfield, expanding the theoretical framework for supersymmetry breaking.

Findings

The model effectively describes Goldstino dynamics.

Comparison shows advantages over previous models.

Couplings to matter and supergravity are feasible.

Abstract

We propose a Goldstino model formulated in terms of a constrained complex linear superfield. Its comparison to other Goldstino models is given. Couplings to supersymmetric matter and supergravity are briefly described.
