英文摘要: We revisit the construction of the viable parameter space of No-Scale F - SU(5), a model built on the F-lipped SU(5) x U(1)(X) gauge group, supplemented by a pair of F-theory derived vectorlike multiplets at the TeV scale, and the dynamically established boundary conditions of No-Scale Supergravity. Employing an updated numerical algorithm and a substantially upgraded computational engine, we significantly enhance the scope, detail and accuracy of our prior study. We sequentially apply a set of "bare-minimal'' phenomenological constraints, consisting of i) the dynamically established boundary conditions of No-Scale Supergravity, ii) consistent radiative electroweak symmetry breaking, iii) precision LEP constraints on the light supersymmetric mass content, iv) the world average top-quark mass, and v) a light neutralino satisfying the 7-year WMAP cold dark-matter relic density measurement. The overlap of the viable parameter space with key rare-process limits on the branching ratio for b -> s gamma and the muon anomalous magnetic moment is identified as the "golden strip'' of F - SU(5). A cross check for top-down theoretical consistency is provided by application of the "Super No-Scale'' condition, which dynamically selects a pair of undetermined model parameters in a manner that is virtually identical to the corresponding phenomenological (driven primarily by the relic density) selection. The predicted vectorlike particles are candidates for production at the future LHC, which is furthermore sensitive to a distinctive signal of ultrahigh multiplicity hadronic jets. The lightest CP-even Higgs boson mass is predicted to be 120(-1)(+3.5):GeV, with an additional 3-4 GeV upward shift possible from radiative loops in the vectorlike multiplets. The predominantly bino flavored lightest neutralino is suitable for direct detection by the Xenon collaboration.
