摘要：

We study the implications for bounds on the top quark pole mass m(t) 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(t) >= 164 GeV, if the light CP even Higgs boson mass m(h) = 125 +/- 2 GeV. We also explore the top quark and Higgs boson masses in two classes of supersymmetric SO(10) models with t-b-tau Yukawa coupling unification at M-GUT. In particular, assuming SO(10) compatible non-universal gaugino masses, setting m(h) = 125 GeV and requiring 5% or better Yukawa unification, we obtain the result 172 GeV <= m(t) <= 175 GeV. Conversely, demanding 5% or better t-b-tau Yukawa unification and setting m(t) = 173.2 GeV, the Higgs boson mass is predicted to lie in the range 122 GeV <= m(h) <= 126 GeV.
