Soft Supersymmetry Breaking Induced by Higher-Derivative Supergravitation in the Electroweak Standard Model

TL;DR

This paper demonstrates how higher-derivative supergravity can induce spontaneous supersymmetry breaking, which then transmits soft breaking terms to the electroweak model, offering a new perspective on the gauge hierarchy problem.

Contribution

It introduces a novel mechanism linking higher-derivative supergravity to soft supersymmetry breaking in the electroweak model, with implications for the hierarchy problem.

Findings

Soft supersymmetry-breaking terms are derived from higher-derivative supergravity.

A new scenario for addressing the gauge hierarchy problem is proposed.

The structure of the soft breaking terms is systematically analyzed.

Abstract

We show how spontaneous supersymmetry breaking in the vacuum state of higher-derivative supergravity is transmitted, as explicit soft supersymmetry-breaking terms, to the effective Lagrangian of the standard electroweak model. The general structure of the soft supersymmetry breaking terms is presented and a new scenario for understanding the gauge hierarchy problem, based on the functional form of these terms, is discussed.
