Gauge mechanism of mediation of supersymmetry breaking

TL;DR

This paper reviews gauge-mediated supersymmetry breaking, discussing its principles, specific models, and their phenomenological and cosmological implications, along with basics of dynamical supersymmetry breaking.

Contribution

It provides a comprehensive analysis of gauge mediation mechanisms and critically examines various models and their implications in supersymmetry breaking.

Findings

Gauge mediation effectively transmits supersymmetry breaking to the Standard Model.

Specific models exhibit distinct phenomenological signatures.

Dynamical supersymmetry breaking mechanisms are fundamental to understanding gauge mediation.

Abstract

Most phenomenologically acceptable supersymmetric models imply breaking of supersymmetry in a separate sector of fields introduced just for this purpose. Supersymmetry breaking is transferred to the Standard Model due to a certain interaction with this additional sector. In this review we disuss one of the popular mechanisms of such mediation with the key role played by the Standard Model gauge interactions. We consider general principles of gauge mediation and give the critical analysis of specific models together with their phenomenological and cosmological implications. We present also basic facts concerning mechanisms of dynamical supersymmetry breaking.
