Twin hypercharges
Nguyen Huy Thao, Nguyen Thi Nguyet Nga, Tran Dinh Tham +1
It is shown that a duplication of the hypercharge, which is identical for the normal sector but different for the dark sector, may manifestly address neutrino mass and dark matter.

Embedding light dark matter and small neutrino mass in the flipped standard model
D. T. Huong, Phung Van Dong, A. E. Carcamo Hernandez
We revisit the flipped standard model where a gauge group is added, determining a dark charge through the weak isospin such as , analogous to the electric charge…

Quasi-Dirac fermion: A source of neutrino mass and dark matter
Nguyen Thi Nguyet Nga, Nguyen Huy Thao, Phung Van Dong
Neutral vectorlike fermion as inspired by unified theories might become quasi-Dirac states at TeV due to a violation in lepton-like symmetry. It is shown that such quasi-Dirac ferm…
