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…
Scoto-seesaw model implied by flavor-dependent Abelian gauge charge
Duong Van Loi, N. T. Duy, Cao H. Nam +1
Assuming fundamental fermions possess a new Abelian gauge charge that depends on flavors of both quark and lepton, we obtain a simple extension of the Standard Model, which reveals…
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 cha…
Flavor-changing phenomenology in a model
N. T. Duy, D. T. Huong, Duong Van Loi +1
We investigate a family-nonuniversal Abelian extension of hypercharge, which significantly alters the phenomenological features of the standard model. Anomaly cancellation requires…
