From A to Z': Combining Anomaly and Z' Mediation of Supersymmetry Breaking

TL;DR

This paper explores a combined approach to supersymmetry breaking mediation using anomaly and Z' mechanisms, addressing specific issues and analyzing phenomenological implications.

Contribution

It introduces a novel combined mediation framework that resolves tachyonic slepton problems and reduces fine-tuning in supersymmetry models.

Findings

Addresses tachyonic slepton problem

Reduces fine-tuning in supersymmetry models

Provides phenomenological insights into combined mediation

Abstract

Combining anomaly with Z' mediation allows us to solve the tachyonic slepton problem of the former and avoid fine tuning in the latter. We describe how the two mechanisms can be combined, and some of the phenomenology of such a joint scenario.
