AbstractWe 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(-1) ATLAS 7 TeV gluino and light stop searches, as well as 13 fb-1 ATLAS and 9.7 fb-1 CMS 8 TeV light stop searches. Most significantly, all five leptonic SUSY searches represent statistically independent data samples. Findings show that all five orthogonal sets of leptonic LHC observations give a lower bound to the gaugino mass scale at M-1/2 >= 680 GeV, with all the current best fits correlating within a narrow region. Furthermore, eight statistically independent 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 range of M-1/2 >= 680-850 GeV, with the upper bound established by the lower experimental limit of the anomalous magnetic moment (g mu - 2)/2 of the muon. We emphasize that this region of the F-SU(5) model space may not be fully probed by leptonic SUSY searches at the LHC until the 13 TeV LHC energizes in 2015. Additionally, we describe an efficient technique for the effective statistical disentanglement of searches sensitive to mutually overlapping event spaces.
