| 英文摘要 | Applying No-Scale Supergravity boundary conditions at a heavy unification scale to the Flipped SU(5) grand unified theory with extra TeV-scale vector-like multiplets, Le. No-Scale T-SU(5), we express the Z-boson mass M-Z as an explicit function of the boundary gaugino mass M-1/2, M-Z(2) = M-Z(2)(M-1/2(2)), with implicit dependence upon a dimensionless ratio c of the supersymmetric Higgs mixing parameter mu and M-1/2. Setting the top Yukawa coupling consistent with m(t) = 174.3 GeV at M-z = 91.2 GeV, the value of c naturally tends toward c similar or equal to 1, which indirectly suggests underlying action of the Giudice-Masiero mechanism. Proportional dependence of all model scales upon the unified gaugino mass M-1/2 in the No-Scale T-SU(5) model suggests one possible mechanism of confronting the electroweak fine-tuning problem.
