We study the grand unification model flipped SU(5) with additional
vector-like particle multiplets, or F-SU(5) for short, in the
framework of General No-Scale Supergravity. In our analysis we allow the
supersymmetry (SUSY) breaking soft terms to be generically non-zero, thereby
extending the phenomenologically viable parameter space beyond the highly
constrained one-parameter version of F-SU(5). In this initial
inquiry, the mSUGRA/CMSSM SUSY breaking terms are implemented. We find this
easing away from the vanishing SUSY breaking terms enables a more broad mass
range of vector-like particles, dubbed flippons, including flippons less than 1
TeV that could presently be observed at the LHC2, as well as a lighter gluino
mass and SUSY spectrum overall. This presents heightened odds that the General
No-Scale F-SU(5) viable parameter space can be probed at the LHC2.
The phenomenology comprises both bino and higgsino dark matter, including a
Higgs funnel region. Particle states emerging from the SUSY cascade decays are
presented to experimentally distinguish amongst the diverse phenomenological
regions.Comment: 8 pages, 4 figures, 4 tables; Version accepted for publication in
