Sparticle Spectroscopy with Neutralino Dark matter from t-b-tau Quasi-Yukawa Unification

TL;DR

This paper explores supersymmetric models with quasi-Yukawa unification, demonstrating their compatibility with neutralino dark matter and predicting sparticle spectra with TeV-scale gluino and squark masses.

Contribution

It shows how t-b-tau quasi-Yukawa unification scenarios can be realized within CMSSM and NUHM1 frameworks, producing viable dark matter and specific sparticle spectra.

Findings

Neutralino dark matter compatible with WMAP data

Sparticle spectra with gluino and squark masses in the TeV range

Multiple dark matter annihilation mechanisms identified

Abstract

We consider two classes of t-b-tau quasi-Yukawa unification scenarios which can arise from realistic supersymmetric SO(10) and SU(4)_C X SU(2)_L X SU(2)_R models. We show that these scenarios can be successfully implemented in the CMSSM and NUHM1 frameworks, and yields a variety of sparticle spectra with WMAP compatible neutralino dark matter. In NUHM1 we find bino-higgsino dark matter as well as the stau coannihilation and A-funnel solutions. The CMSSM case yields the stau coannihilation and A-funnel solutions. The gluino and squark masses are found to lie in the TeV range.
