Abstract

We identify a class of supersymmetric SU(4)(c) x SU(2)(L) x SU(2)(R) models in which imposing essentially perfect t-b-tau Yukawa coupling unification at M-GUT yields a mass close to 122-126 GeV for the lightest CP-even (SM-like) Higgs boson. The squark and gluino masses in these models exceed 3 TeV, but the stau and charginos in some cases can be considerably lighter. We display some benchmark points corresponding to neutralino-stau and bino-wino coannihilations as well as A-resonance. The well-known MSSM parameter tan beta is around 46-52.
