The F-SU(5) Model with Various Supersymmetry Breaking Soft Terms
MetadataShow full item record
The flipped SU(5) grand unification model with additional vector-like multiplets (FSU(5)) in the framework of General No-scale Supergravity is studied. The highly constrained soft supersymmetry breaking terms of the one-parameter F-SU(5) are relaxed to allow the high-energy boundary conditions to be generically non-zero. The phenomenological viable parameter space is therefore expanded. In this project the CMSSM/mSUGRA and D-brane inspired soft supersymmetry breaking terms are implemented and studied. The non-vanishing soft terms are found to produce a broader mass range of vector-like particles and a lighter SUSY spectrum, increasing the probability that the parameter space can be probed during the LHC run 2. Both bino and higgsino dark matter are generated by this model, as well as a Higgs Funnel scenario. Particle compositions from the SUSY cascade decay modes are presented to distinguish the different scenarios phenomenologically.
