P. V. Dong, T. D. Tham, and H. T. Hung, 2013. 3-3-1-1 model for dark matter. Physical Review D 87, 115003.
Proposed a framework that nontrivially unifies electroweak and B-L interactions, called 3-3-1-1 model, and probes important experimental issues. Dark matter is a neutral fermion or scalar with wrong B-L number, which is unified with normal matter in gauge multiplet and stabilized by a residual gauge symmetry (matter parity). Neutrinos gain suitable mass via seesaw mechanisms resulting from the spontaneous gauge symmetry breaking. The B-L breaking field induces the inflationary expansion of the early universe. The lighest right-handed neutrino can CP-asymmtrically decay into dark matter and normal matter, explaining the baryon asymmetry. The model solves electric charge quantization, flavor questions, unitarity, and CPT invariance completely [see also: PRD90(2014)075021; 91(2015)055023; 92(2015)055026; 93(2016)115003]
