英文摘要	In light of recent 80-137 fb(-1) results at the LHC Run 2 establishing a lower gluino mass limit of 2.25 TeV, we revisit the supersymmetric GUT model Flipped SU(5) with extra vector-like particles, known as F-SU(5), with vanishing No-Scale Supergravity boundary conditions at the string scale of about 2 x 10(17) GeV, including the supersymmetry breaking B-mu parameter which is strictly enforced as B-mu = 0. Given the proportional dependence of all model scales on a single parameter M-1/2, No-Scale F-SU(5) was shown to possess no electroweak fine-tuning and thus persists as a natural one-parameter model. In this fresh analysis here, we demand consistency with the measured 125 GeV light Higgs boson mass, though we forgo an upper limit on the lightest neutralino relic density. The resulting phenomenology delivers a gluino mass of M((g) over tilde) less than or similar to 7.5 TeV and a lightest supersymmetric particle (LSP) of M((chi) over tilde (0)(1)) less than or similar to 1.6 TeV. In order to dilute the relic density down to the WMAP and Planck measurements, we rely upon a single cosmological master coupling lambda(6). (C) 2019 The Authors. Published by Elsevier B.V.
