Brazilian Report on Dark Matter 2024
I. F. M. Albuquerque, J. Alcaniz, A. Alves +51
One of the key scientific objectives for the next decade is to uncover the nature of dark matter (DM). We should continue prioritizing targets such as weakly-interacting massive pa…
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…
Vacuum stability and spontaneous violation of the lepton number at low energy scale in a model for light sterile neutrinos
João Paulo Pinheiro, C. A. de S. Pires
It is well known that the Standard Model of the Electroweak interactions rests on a metastable vacuum. This can only be fixed by means of new physics. Presently neutrino physics pr…
Brazilian Community Report on Dark Matter
E. Abdalla, I. F. M. Albuquerque, A. Alves +52
This white paper summarizes the activities of the Brazilian community concerning dark matter physics and highlights the importance of financial support to Brazilian groups that are…
A cosmologically viable eV sterile neutrino model
C. A. de S. Pires
The MiniBooNE collaboration recently released a report claiming have observed an excess of electron and anti-electron neutrino with significance of C.L. corroborating, i…
Implementing the inverse type-II seesaw mechanism into the 3-3-1 model
Carlos Antônio de Sousa Pires, Felipe Ferreira de Freitas, Jing Shu +2
After the LHC is turning on and accumulating more data, the TeV scale seesaw mechanisms for small neutrino masses in the form of inverse seesaw mechanisms are gaining more and more…
