High Scale SUSY Breaking From Topological Inflation

TL;DR

This paper proposes that topological inflation can explain the high energy scale of SUSY breaking suggested by the Higgs mass, offering a potential solution to the hierarchy problem.

Contribution

It introduces a novel connection between topological inflation and high-scale SUSY breaking, providing a possible explanation for the observed Higgs mass.

Findings

Pure gravity mediation can address the high SUSY breaking scale.

Topological inflation can be the last inflation in the early universe.

A chaotic inflation model can also yield similar solutions.

Abstract

The recently observed mass ~ 125 GeV for the Higgs boson suggests a high-energy scale SUSY breaking, above O(10) TeV. It is, however, very puzzling why nature chooses such a high energy scale for the SUSY breaking, if the SUSY is a solution to the hierarchy problem. We show that the pure gravity mediation provides us with a possible solution to this puzzle if the topological inflation is the last inflation in the early universe. We briefly discuss a chaotic inflation model in which a similar solution can be obtained.
