or Conspiring Noise?

We examine the ATLAS and CMS 7 & 8 TeV multijet supersymmetry (SUSY) searches requiring the incidence of a single lepton in the framework of the supersymmetric grand unified model No-Scale Flipped SU(5) with extra vector-like flippon multiplets derived from F-Theory, or F-SU(5) for short. Investigated are five multijet+lepton SUSY searches: 4.7/fb ATLAS 7 TeV gluino and light stop searches, as well as 13/fb ATLAS and 9.7/fb CMS 8 TeV light stop searches. Most significantly, all five leptonic SUSY searches represent statistically independent data samples. Findings show that best fits to all five orthogonal sets of leptonic LHC observations correlate within a narrow region of the gaugino mass scale at M_{1/2} = 752+-77 GeV. Even more fundamental and significant, all LHC SUSY search regions (leptonic + all-hadronic) accessible to the No-Scale F-SU(5) model space intersect with all the currently operating beyond the Standard Model experiments within the very constrained range of M_{1/2} = 765+-85 GeV, derived from eight statistically independent LHC data sets. In the absence of new physics, such a correlation would require several parallel random fluctuations or an unknown global systematic anomaly near the same SUSY mass. We discuss the implications and consequences of maintaining this consistency with the 20/fb of data recorded in 2012 at 8 TeV to be analyzed in 2013, soon to augment these statistically independent SUSY searches with yet additional mutually exclusive results.
