Heavy bino dark matter and collider signals in the MSSM with vectorlike fourth-generation particles
MSSM4G models, in which the minimal supersymmetric standard model is extended to include vectorlike copies of standard model particles, are promising possibilities for weak-scale supersymmetry. In particular, two models, called QUE and QDEE, realize the major virtues of supersymmetry (naturalness consistent with the 125 GeV Higgs boson, gauge coupling unification, …
