Constraints from the SM-like Higgs boson in a flavor-dependent extension of the Standard Model
Duong Van Loi, N. T. Duy
This work presents a phenomenological study of the Standard Model-like Higgs boson in a flavor-dependent extension of the Standard Model, where the charge is assig…
Generation-separated hypercharges and dark charges: origin of flavor, neutrino masses, and dark matter
Duong Van Loi
We study a framework with generation-separated hypercharges and dark charges. After the extended hypercharge symmetry is spontaneously…
Physical implications of a double right-handed gauge symmetry
Duong Van Loi, A. E. Cárcamo Hernández, N. T. Duy +2
Guided by the flipping principle, we propose a novel extension of the Standard Model based on a double right-handed gauge symmetry. In this framework, all left-handed fermio…
Lepton Flavor Physics in the flipped 3-3-1-1 Model: Non-Universality and Violation
D. T. Huong, V. H. Binh, N. T. Huong +3
We investigate the flavor violation (FV) of Z decays to leptons at tree level and flavor conserving Z decays to leptons in the frame work of the flipped $ SU(3)_C\otimes SU(3)_L \o…
Dark symmetry implication for right-handed neutrinos
Phung Van Dong, Duong Van Loi, Do Thi Huong +2
We argue that the long-standing issues of neutrino mass and dark matter can be manifestly solved in a dark gauge symmetry that transforms nontrivially only for three right…
Questions of flavor physics and neutrino mass from a flipped hypercharge
Duong Van Loi, Phung Van Dong, N. T. Duy +1
The flavor structure of quarks and leptons is not yet fully understood, but it hints a more fundamental theory of non-universal generations. We therefore propose a simple extension…
Scotoseesaw model implied by dark right-handed neutrinos
Phung Van Dong, Duong Van Loi
We find a dark gauge symmetry that transforms nontrivially only for three right-handed neutrinos, . The anomaly cancellation demands that they have a dark char…
Scotogenic model from an extended electroweak symmetry
Phung Van Dong, Duong Van Loi
We argue that the higher weak isospin manifestly unifies dark matter and normal matter in its isomultiplets for which dark matter carries a conserved dark charge while no…
Flavor-dependent extension inspired by lepton, baryon and color numbers
Duong Van Loi, Phung Van Dong
There is no reason why the gauge symmetry extension is family universal as in the standard model and the most well-motivated models, e.g. left-right symmetry and grand unification.…
Physics implication from higher weak isospin decomposition
Phung Van Dong, Duong Van Loi
The symmetry actually studied is directly broken to the electroweak symmetry by a Higgs triplet, predicting a relevant new physics a…
Phenomenology of a minimal extension of the standard model with a family-dependent gauge symmetry
Duong Van Loi, Cao H. Nam, Phung Van Dong
We consider a gauge symmetry extension of the standard model given by with minimal particle content, where and $…
Abelian charge inspired by family number
Phung Van Dong, Tran Ngoc Hung, Duong Van Loi
Quark has an electric charge either or and a baryon number , where the divisions 's match the color number. Although the electric charge and the baryon number…
Can the Higgs field feel a dark force?
Phung Van Dong, Duong Van Loi, Do Thi Huong
We argue that if an electroweak Higgs field possesses a dark gauge charge responsible for dark matter stability, the -boson mass deviation is properly induced, besides appropria…
Novel effects of the -boson mass shift in the 3-3-1 model
Duong Van Loi, Phung Van Dong
The recent precision measurement of the -boson mass reveals an exciting hint for the new physics as of the 3-3-1 model. We indicate that the 3-3-1 model contains distinct source…
Gauge origin of double dark parity and implication for dark matter
Duong Van Loi, Phung Van Dong
Dark matter must be stabilized over the cosmological timescale, which demands the existence of a stabilizing symmetry, derived by a dark charge, . The existence of this dark cha…
Dequantization of electric charge: Probing scenarios of cosmological multi-component dark matter
Duong Van Loi, Nguyen Manh Duc, Phung Van Dong
Since the electric charge in the standard model is theoretically not quantized, we may have a variant of it, called dark charge. Similar to the electric charge, the dark charge nei…
Canonical seesaw implication for two-component dark matter
Phung Van Dong, Cao H. Nam, Duong Van Loi
We show that the canonical seesaw mechanism implemented by the gauge symmetry provides two-component dark matter naturally. The seesaw scale that breaks defines…
Multicomponent dark matter in noncommutative gauge theory
Cao H. Nam, Duong Van Loi, Le Xuan Thuy +1
It is shown that for a higher weak isospin symmetry, with , the baryon minus lepton charge neither commutes nor closes algebraically with similar…
Dark charge versus electric charge
Duong Van Loi, Cao H. Nam, Ngo Hai Tan +1
We revisit a theory that proposes a dark charge, , as a dequantization of the electric charge, . We find that the general arguments of anomaly cancelation and fermion mass ge…
Asymmetric matter from symmetry breaking
Phung Van Dong, Duong Van Loi
The present matter content of our universe may be governed by a symmetry -- the simplest gauge completion of the seesaw mechanism which produces small neutrino masses.…
Neutrino mass and dark matter from an approximate symmetry
Duong Van Loi, Phung Van Dong, Dang Van Soa
We argue that neutrino mass and dark matter can arise from an approximate symmetry. This idea can be realized in a minimal setup of the flipped 3-3-1 model, which discriminat…
