Universality in Pure Gravity Mediation

TL;DR

This paper explores the viability of scalar mass universality in pure gravity mediation models with low tan beta, analyzing their low-energy phenomenological implications in the context of supersymmetry and Higgs mass constraints.

Contribution

It demonstrates that scalar mass universality can be maintained in pure gravity mediation models with low tan beta, providing detailed analysis of their observable consequences.

Findings

Scalar mass universality remains viable for tan beta 2.5.

Multi-TeV scalar masses are compatible with a 125 GeV Higgs.

Low energy phenomenology of these models is thoroughly discussed.

Abstract

If low energy supersymmetry is realized in nature, the apparent discovery of a Higgs boson with mass around 125 GeV points to a supersymmetric mass spectrum in the TeV or multi-TeV range. Multi-TeV scalar masses are a necessary component of supersymmetric models with pure gravity mediation or in any model with strong moduli stabilization. Here, we show that full scalar mass universality remains viable as long as the ratio of Higgs vevs, tan beta is relatively small (\lesssim 2.5). We discuss in detail the low energy (observable) consequences of these models.
