The 3-3-1 Model: a natural framework for sub-MeV dark matter
Vinicius Oliveira, D. Cogollo, A. Doff +1
We show that the model with right-handed neutrinos naturally accommodates a viable sub-MeV dark matter (DM) candid…
Exploring the viability of pseudo Nambu-Goldstone boson as ultralight dark matter in a mass range relevant for strong gravity applications
António P. Morais, Vinícius Oliveira, António Onofre +2
We study a simple extension of the Standard Model featuring a dark sector with an ultralight pseudo Nambu-Goldstone boson as dark matter candidate. We focus on the mass range $\mat…
Bounds on quark mixing, and mixing angle from flavor changing neutral processes in a 3-3-1 model
Vinícius Oliveira, C. A. de S. Pires
Meson and anti-meson mixing processes constitute an important source of constraints on models that give tree level contributions to flavor violating neutral processes. In electrowe…
Flavor Changing Neutral Current processes and family discrimination in 3-3-1 models
Vinícius Oliveira, C. A. de S. Pires
In 3-3-1 models anomaly cancellation requires that one of the three families of quarks transforms as triplet by with the other two transforming necessarily…
Pandax-4T limits on mass in 3-3-1LHN model
Vinícius Oliveira, C. A. de S. Pires
The framework of the so-called 3-3-1LHN model may accommodate two different, but viable, scenarios of dark matter: one involving a heavy Dirac neutrino , , or another having a…
A model for mixed warm and hot right-handed neutrino dark matter
Maíra Dutra, Vinícius Oliveira, C. A. de S. Pires +1
We discuss a model where a mixed warm and hot keV neutrino dark matter rises naturally. We arrange active and sterile neutrinos in the same multiplet, with the lightest s…
