摘要：
We study the implications for bounds on the top quark pole mass mt 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 mt ≥ 164 GeV, if the light CP even Higgs boson mass mh = 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 MGUT. In particular, assuming SO(10) compatible non-universal gaugino masses, setting mh = 125 GeV and requiring 5% or better Yukawa unification, we obtain the result 172 GeV ≤ mt ≤ 175 GeV. Conversely, demanding 5% or better t-b-τ Yukawa unification and setting mt = 173.2 GeV, the Higgs boson mass is predicted to lie in the range 122 GeV ≤ mh ≤ 126 GeV.
