中文摘要	We study the lightest CP-even Higgs boson mass in five kinds of testable flipped SU(5) x U(1)(X) models from F-theory. Two kinds of models have vectorlike particles around the TeV scale, while the other three kinds also have the vectorlike particles at the intermediate scale that can be considered as messenger fields in gauge-mediated supersymmetry breaking. We require that the Yukawa couplings for the TeV-scale vectorlike particles and the third family of the Standard Model (SM) fermions are smaller than three from the electroweak scale to the SU(3)(C) x SU(2)(L) unification scale. With the two-loop renormalization group equation running for the gauge couplings and Yukawa couplings, we obtain the maximal Yukawa couplings between the TeV-scale vectorlike particles and Higgs fields. To calculate the lightest CP-even Higgs boson mass upper bounds, we employ the renormalization group improved effective Higgs potential approach, and consider the two-loop leading contributions in the supersymmetric SM and one-loop contributions from the TeV-scale vectorlike particles. We assume maximal mixings between the stops and between the TeV-scale vectorlike scalars. The numerical results for these five kinds of models are roughly the same. In particular, we showthat the lightest CP-even Higgs boson can have mass up to 146 GeV naturally, which is the current upper bound from the CMS and ATLAS collaborations.
