Higgs and Sparticle Spectroscopy with Gauge-Yukawa Unification

Understand

We explore the Higgs and sparticle spectroscopy of supersymmetric SU(4)_c x SU(2)_L x SU(2)_R models in which the three MSSM gauge couplings and third family (t-b-tau) Yukawa couplings are all unified at M_GUT.

• This class of models can be obtained via compactification of a higher dimensional theory.
• Allowing for opposite sign gaugino masses and varying m_t within 1 sigma of its current central value yields a variety of gauge-Yukawa unification as well as WMAP compatible neutralino dark matter solutions.
• They include mixed bino-Higgsino dark matter, stau and gluino coannihilation scenarios, and the A-resonance solution.
