Dark Matter in SuperGUT Unification Models

TL;DR

This paper explores dark matter prospects in superGUT unification models, highlighting how unifying parameters above the GUT scale can revive no-scale supergravity as a viable dark matter framework.

Contribution

It analyzes the impact of superGUT unification on dark matter candidates, especially the neutralino, and demonstrates the potential to set scalar masses to zero at the unification scale.

Findings

SuperGUT unification allows vanishing scalar masses.

No-scale supergravity can be phenomenologically viable.

Neutralino remains a consistent dark matter candidate.

Abstract

After a brief update on the prospects for dark matter in the constrained version of the MSSM (CMSSM) and its differences with models based on minimal supergravity (mSUGRA), I will consider the effects of unifying the supersymmetry-breaking parameters at a scale above M_{GUT}. One of the consequences of superGUT unification, is the ability to take vanishing scalar masses at the unification scale with a neutralino LSP dark matter candidate. This allows one to resurrect no-scale supergravity as a viable phenomenological model.
