Neutral SU(2) Gauge Extension of the Standard Model and a Vector-Boson Dark-Matter Candidate
Abstract
If the standard model of particle interactions is extended to include a neutral SU(2)N gauge factor, with SU(3)C x SU(2)L x U(1)Y x SU(2)N embedded in E6 or [SU(3)]3, a conserved generalized R parity may appear. As a result, we have the first example of a possible dark-matter candidate X1 which is a non-Abelain vector boson. Using current data, its mass is predicted to be less than about 1 TeV. The associated Z' of this model, as well as some signatures of the Higgs sector, should then be observable at the LHC (Large Hadron Collider).
