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…
Unifying the electroweak and B-L interactions
P. V. Dong
We argue that the gauge symmetry which includes SU(3)_L as a higher weak-isospin symmetry is manifestly given by SU(3)_C\otimes SU(3)_L\otimes U(1)_X\otimes U(1)_N, where the last…
Inflation and leptogenesis in the 3-3-1-1 model
D. T. Huong, P. V. Dong, C. S. Kim +1
We consider the SU(3)_C \otimes SU(3)_L \otimes U(1)_X \otimes U(1)_N (3-3-1-1) model at the GUT scale with implication for inflation and leptogenesis. The mass spectra of the neut…
Investigation of Dark Matter in Minimal 3-3-1 Models
P. V. Dong, C. S. Kim, D. V. Soa +1
It is shown that the 3-3-1 model with the minimal lepton content can work as two-Higgs-triplet 3-3-1 model while leaving the other scalars as inert particles responsible for dark m…
3-3-1-1 model for dark matter
P. V. Dong, H. T. Hung, T. D. Tham
We show that the SU(3)_C X SU(3)_L X U(1)_X (3-3-1) model of strong and electroweak interactions can naturally accommodate an extra U(1)_N symmetry behaving as a gauge symmetry. Re…
Question of Peccei-Quinn symmetry and quark masses in the economical 3-3-1 model
P. V. Dong, H. T. Hung, H. N. Long
We show that there is an infinite number of U(1) symmetries like Peccei-Quinn symmetry in the 3-3-1 model with minimal scalar sector---two scalar triplets. Moreover, all of them ar…
The S_3 flavor symmetry in 3-3-1 models
P. V. Dong, H. N. Long, C. H. Nam +1
We propose two 3-3-1 models (with either neutral fermions or right-handed neutrinos) based on S_3 flavor symmetry responsible for fermion masses and mixings. The models can be dist…
A simple model of gauged lepton and baryon charges
P. V. Dong, H. N. Long
We argue that simpler fermionic contents, responsible for the extension of the standard model with gauged lepton and baryon charges, can be constructed by assuming existence of so-…
The 3-3-1 model with S_4 flavor symmetry
P. V. Dong, H. N. Long, D. V. Soa +1
We construct a 3-3-1 model based on family symmetry S_4 responsible for the neutrino and quark masses. The tribimaximal neutrino mixing and the diagonal quark mixing have been obta…
The economical SU(3)_C X SU(3)_L X U(1)_X model
P. V. Dong, H. N. Long
In this report the SU(3)_C X SU(3)_L X U(1)_X gauge model with minimal scalar sector, two Higgs triplets, is presented in detail. One of the vacuum expectation values is a sour…
SU(3)_C X SU(3)_L X U(1)_X model with two Higgs triplets
P. V. Dong, H. N. Long, D. T. Nhung +1
The gauge model with the minimal scalar sector (two Higgs triplets) is studied in detail. One of the vacuum expectation values is a source of lepto…
