Axionic Mirage Mediation

TL;DR

This paper introduces an axionic mirage mediation model that dynamically determines the Peccei-Quinn symmetry breaking scale and addresses key issues in supersymmetry, with the axino as the lightest sparticle.

Contribution

It presents a novel mirage mediation framework incorporating Peccei-Quinn symmetry, solving the $mbda$-problem and moduli problem simultaneously.

Findings

Peccei-Quinn symmetry breaking scale is dynamically set around 10^{10}-10^{12} GeV.

The model resolves the $mbda$-problem and moduli problem.

The axino becomes the lightest supersymmetric particle.

Abstract

In this talk, we propose a model of mirage mediation, in which Peccei-Quinn symmetry is incorporated. In this \textit{axionic mirage mediation}, it is shown that the Peccei-Quinn symmetry breaking scale is dynamically determined around $10^{10}$ GeV to $10^{12}$ GeV due to the supersymmetry breaking effects. The problems in the original mirage mediation such as the $\mu$-problem and the moduli problem can be solved simultaneouly. Furthermore, in our model the axino, which is the superpartner of the axion, is the lightest sparticle.
