Dark Horse, Dark Matter: Revisiting the SO(16)x SO(16)' Nonsupersymmetric Model in the LHC and Dark Energy Era

Abstract: We revisit the nonsupersymmetric SO(16)x SO(16)' model in light of LHC and Dark Energy data. Recently nonsupersymmetric models have become of great interest because the LHC has not found evidence of supersymmetry. In addition nonsupersymmetric models with a single Higgs-like field and small one loop vacuum energy have been constructed. Also models of dark energy with a dilaton-radion potential have also been recently examined in the light of dark energy data and the swampland conjecture. In this paper some of the features of the nonsupersymmetric SO(16)x SO(16)' model with regards to high energy physics and cosmology such as dark energy, vacuum stablilization, dark matter candidates, dark matter portals, gauge-Higgs unification, and quantum cosmology are examined in the context of the LHC and dark energy era.
