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…
Theoretical and Experimental Constraints on Multi-Component Dark Matter Models
J. P. Carvalho-Corrêa, I. M. Pereira, B. L. Sánchez-Vega +1
A complete assessment of any dark matter model requires confronting its low-energy phenomenology with its high-scale theoretical viability. We undertake such a dual analysis for a…
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…
Vacuum stability conditions of the economical 3-3-1 model from copositivity
B. L. Sánchez-Vega, G. Gambini, C. E. Alvarez-Salazar
By applying copositivity criterion to the scalar potential of the economical model, we derive necessary and sufficient bounded-from-below conditions at tree level. Although…
Mu-tau reflection symmetry with a high scale texture-zero
C. C. Nishi, B. L. Sánchez-Vega, G. Souza Silva
The -reflection symmetric neutrino mass matrix can accommodate all known neutrino mixing angles, with maximal atmospheric angle fixed, and predicts all the unknown CP phases of…
New constraints on the 3-3-1 model with right-handed neutrinos
B. L. Sánchez-Vega, E. R. Schmitz, J. C. Montero
In the framework of a 3-3-1 model with right-handed neutrinos and three scalar triplets we consider different spontaneous symmetry breaking patterns seeking for a non-linear realiz…
Mu-tau reflection symmetry with a texture-zero
C. C. Nishi, B. L. Sánchez-Vega
The -reflection symmetry is a simple symmetry capable of predicting all the unknown CP phases of the lepton sector and the atmospheric angle but too simple to predict the absol…
Axion Like Particles and the Inverse Seesaw Mechanism
C. D. R. Carvajal, A. G. Dias, C. C. Nishi +1
Light pseudoscalars known as axion like particles (ALPs) may be behind physical phenomena like the Universe transparency to ultra-energetic photons, the soft -ray excess from th…
