Dark Matter Freeze-In during Warm Inflation and the Seesaw Mechanism
Rayff de Souza, Jamerson G. Rodrigues, Clarissa Siqueira +2
A compelling way to address the inflationary period is via the warm inflation scenario, where the interaction of the inflaton field with other degrees of freedom affects its dynami…
Discrepancy between cosmological and electroweak observables in Higgs Inflation
J. G. Rodrigues, Micol Benetti, Jailson S. Alcaniz
In this work, we revisit the non-minimally coupled Higgs Inflation scenario and investigate its observational viability in light of the current Cosmic Microwave Background, Baryon…
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…
Neutrino masses, cosmological inflation and dark matter in a model with type II seesaw mechanism
J. G. Rodrigues, A. C. O. Santos, J. G. Ferreira +1
In this work we implement the type II seesaw mechanism into the framework of the gauge model. As main gain, the right-handed neutrinos of the model get free to play th…
Inflation scenario driven by a low energy physics inflaton
J. G. Ferreira, C. A. de S. Pires, J. G. Rodrigues +1
It is a longstanding desire of cosmologists, and particle physicists as well, to connect inflation to low energy physics, culminating, for instance, in what is known as Higgs infla…
Embedding cosmological inflation, axion dark matter and seesaw mechanism in a 3-3-1 gauge model
J. G. Ferreira, C. A de S. Pires, J. G. Rodrigues +1
The Peccei-Quinn symmetry is an automatic symmetry of the 3-3-1 gauge models which, consequently are not plagued with the strong CP problem. Nevertheless, the axion that emerges fr…
