Higgs and non-universal gaugino masses: no SUSY signal expected yet?

TL;DR

This paper explores how recent Higgs results impact supersymmetry models with non-universal gaugino masses, showing that such models can evade current LHC and dark matter detection constraints, explaining the lack of SUSY signals.

Contribution

It analyzes the implications of Higgs measurements for non-universal gaugino mass models within SU(5) unification, highlighting their viability and experimental inaccessibility.

Findings

Viable spectra are produced that are largely inaccessible to current experiments.

Non-universal gaugino mass models can explain the absence of SUSY signals.

Higgs results constrain but do not exclude these SUSY scenarios.

Abstract

So far, no supersymmetric particles have been detected at the Large Hadron Collider (LHC). However, the recent Higgs results have interesting implications for the SUSY parameter space. In this paper, we study the consequences of an LHC Higgs signal for a model with non-universal gaugino masses in the context of SU(5) unification. The gaugino mass ratios associated with the higher representations produce viable spectra that are largely inaccessible to the current LHC and direct dark matter detection experiments. Thus, in light of the Higgs results, the non-observation of SUSY is no surprise.
