Higgs and Sparticle Spectroscopy with Gauge-Yukawa Unification
Abstract
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 MGUT. This class of models can be obtained via compactification of a higher dimensional theory. Allowing for opposite sign gaugino masses and varying mt 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.
