英文摘要 | The F-lipped SU(5) x U(1)(X) grand unified theory supplemented by TeV-scale vectorlike particles from F-theory, together dubbed F-SU(5), offers a natural multiphase unification process which suggests an elegant implementation of the no-scale supergravity boundary conditions at the unification scale M(F) similar or equal to 7 x 10(17) GeV. Enforcing the no-scale boundary conditions, including B(mu)(M(F)) = 0 on the Higgs bilinear soft term, with the precision 7-year WMAP value on the dark matter relic density isolates a highly constrained "golden point" located near M(1/2) = 455 GeV and tan beta = 15 in the tan beta-M(1/2) plane, which simultaneously satisfies all known experiments, and moreover corresponds to an imminently observable proton decay rate. Because the universal gaugino mass is actually determined from established low energy data via renormalization group equation running, there are no surviving arbitrary scale parameters in the present model. |
