Testable SUSY spectra from GUTs at a 100 TeV pp collider

TL;DR

This paper explores how supersymmetric GUT models can be tested at a future 100 TeV proton-proton collider by analyzing their predicted superpartner masses, which are beyond LHC reach but accessible at higher energies.

Contribution

It demonstrates how comparing GUT model predictions with fermion mass data constrains SUSY spectra and shows that superpartner masses are testable at a 100 TeV collider.

Findings

Superpartner masses are just beyond LHC run 1 reach.

Predicted SUSY spectra are accessible at a 100 TeV collider.

Constraints from fermion masses inform SUSY model predictions.

Abstract

Grand Unified Theories (GUTs) are attractive candidates for more fundamental elementary particle theories. They can not only unify the Standard Model (SM) interactions but also different types of SM fermions, in particular quarks and leptons, in joint representations of the GUT gauge group. We discuss how comparing predictive supersymmetric GUT models with the experimental results for quark and charged lepton masses leads to constraints on the SUSY spectrum. We show an example from a recent analysis where the resulting superpartner masses where found just beyond the reach of LHC run 1, but fully within the reach of a 100 TeV pp collider.
