摘要We establish that the light Higgs boson mass in the context of the No-Scale Flipped SU(5) GUT with TeV-scale vector-like matter multiplets (flippons) is consistent with m(h) = 125.5 +/- 0.5 GeV in the region of the best supersymmetry (SUSY) spectrum fit to low statistics data excesses observed by ATLAS in multijet and light stop 5 fb(-1) SUSY searches at the LHC7. Simultaneous satisfaction of these disparate goals is achieved by employing a minor decrease in the SU(5) partial unification scale M-32 to lower the flippon mass, inducing a larger Higgs boson mass shift from the flippon loops. The reduction in M-32, which is facilitated by a phenomenologically favorable reduction of the low-energy strong coupling constant, moreover suggests an imminently observable (e vertical bar mu)(+)pi(0) proton decay with a central value time scale of 1.7 x 10(34) years. At the same point in the model space, we find a lightest neutralino mass of m(chi) = 145 GeV, which is suitable for the production of 130 GeV monochromatic gamma-rays through annihilations yielding associated Z-bosons; a signal with this energy signature has been identified within observations of the galactic center by the FERMI-LAT Space Telescope. In conjunction with direct correlations to the fate of the ATLAS multijet and light stop production channels presently being tested at the LHC8, we suggest that the reality of a 125.5 GeV Higgs boson affords a particularly rich company of specific and imminently testable associated observables.
