Supersymmetric SO(10) Grand Unification at the LHC and Beyond

TL;DR

This paper explores supersymmetric SO(10) grand unification models, analyzing their low-energy phenomenology, fine-tuning, dark matter constraints, and collider benchmarks to guide future experimental searches.

Contribution

It introduces new scenarios with non-universal gaugino masses, examines fine-tuning excluding mu, and provides collider benchmarks for SO(10) GUT models.

Findings

Identified viable parameter spaces consistent with Higgs mass and dark matter constraints.

Determined high-scale Yukawa ratios aligning with theoretical predictions.

Proposed collider benchmarks for future LHC and collider experiments.

Abstract

We study models of supersymmetric grand unification based on the SO(10) gauge group. We investigate scenarios of non-universal gaugino masses including models containing a mixture of two representations of hidden sector chiral superfields. We analyse the effect of excluding mu from the fine-tuning measure, and confront the results with low energy constraints, including the Higgs boson mass, dark matter relic density and supersymmetry bounds. We also determine high scale Yukawa coupling ratios and confront the results with theoretical predictions. Finally, we present two additional benchmarks that should be explored at the LHC and future colliders.
