Confronting SUSY GUT with Dark Matter, Sparticle Spectroscopy and Muon $(g-2)$

TL;DR

This paper investigates how different grand unified theories, specifically $SO(10)$ and 4-2-2 models, influence supersymmetric particle spectra and their compatibility with LHC, dark matter, and muon g-2 experimental results.

Contribution

It compares two GUT models, highlighting how their gauge structures affect supersymmetric spectra and experimental correlations, especially in dark matter and muon g-2.

Findings

4-2-2 model allows larger parameter space than $SO(10)$

Multiple coannihilation scenarios are compatible with current data

Distinct correlations between GUT structure and experimental signatures

Abstract

We explore the implications of LHC and cold dark matter searches for supersymmetric particle mass spectra in two different grand unified models with left-right symmetry, $SO(10)$ and $ SU(4)_c \times SU(2)_L \times SU(2)_R$ (4-2-2). We identify characteristic differences between the two scenarios, which imply distinct correlations between experimental measurements and the particular structure of the GUT group. The gauge structure of 4-2-2 enhances significantly the allowed parameter space as compared to $SO(10)$, giving rise to a variety of coannihilation scenarios compatible with the LHC data, LSP dark matter and the ongoing muon g-2 experiment.
