| 中文摘要 | We present the distinctive collider signatures of no-scale F-SU(5), a highly efficient and phenomenologically favored model built on the tripodal foundations of the F-lipped SU(5) x U(1)(X) grand unified theory, extra F-theory derived TeV scale vectorlike particle multiplets, and the dynamic high-scale boundary conditions of no-scale supergravity. The identifying features of the supersymmetric spectrum are a light stop and gluino, with both sparticles much lighter than all the additional squarks. This unique mass hierarchy leads to the enhanced production of events with an ultrahigh multiplicity of hadronic jets, which should be clearly visible to the root s = 7 TeV LHC at only 1 fb(-1) of integrated luminosity. We suggest a modest alternative event cutting procedure based around a reduced minimal transverse momentum per jet (p(T) > 20 GeV), and an increased minimal multiplicity (>= 9) of distinct jets per subscribed event. These criteria optimize the F-SU(5) signal-to-background ratio, while readily suppressing the contribution of all standard model processes, allowing moreover a clear differentiation from competing models of new physics, most notably minimal supergravity. The characteristic no-scale signature is quite stable across the viable parameter space, modulo an overall rescaling of the mass spectrum; detection by the LHC of the ultrahigh jet signal would constitute a suggestive evocation of the intimately linked stringy origins of F-SU(5) and could possibly provide a glimpse into the underlying structure of the fundamental string moduli. |
