Top quark and Higgs boson masses in supersymmetric models.

We study the implications for bounds on the top quark pole mass m in models with low scale supersymmetry following the discovery of the Standard Model-like Higgs boson. In the minimal supersymmetric standard model, we find that m ≥ 164 GeV, if the light CP even Higgs boson mass m = 125 ± 2 GeV. We also explore the top quark and Higgs boson masses in two classes of supersymmetric SO(10) models with t-b- τ Yukawa coupling unification at M. In particular, assuming SO(10) compatible non-universal gaugino masses, setting m = 125 GeV and requiring 5% or better Yukawa unification, we obtain the result 172 GeV ≤ m ≤ 175 GeV. Conversely, demanding 5% or better t- b- τ Yukawa unification and setting m = 173 .2 GeV, the Higgs boson mass is predicted to lie in the range 122 GeV ≤ m ≤ 126 GeV. [ABSTRACT FROM AUTHOR]
