In the supersymmetric Pati-Salam framework, light bino-like neutralino dark matter below 110 GeV survives all constraints in bulk and Z-funnel regions for negative mu, with a right-handed stau next-to-lightest particle below 120 GeV.

abstract
We discuss ways to probe t-b-tau Yukawa coupling unification condition at the Energy and Intensity frontiers. We consider non-universal soft supersymmetry breaking mass terms for gauginos related by the SO(10) grand unified theory (GUT). We have previously shown that t-b-tau Yukawa coupling unification prefers a mass of around 125 GeV for the Standard Model-like Higgs boson with all colored sparticle masses above 3 TeV. The well-known MSSM parameter tan(beta) is about 47-48 and neutralino-stau coannihilation yields the desired relic dark matter density.

Light Neutralino Dark Matter in a Supersymmetric Pati-Salam Framework
In the supersymmetric Pati-Salam framework, light bino-like neutralino dark matter below 110 GeV survives all constraints in bulk and Z-funnel regions for negative mu, with a right-handed stau next-to-lightest particle below 120 GeV.
