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…
Is natural inflation in agreement with CMB data?
F. B. M. dos Santos, G. Rodrigues, J. G. Rodrigues +2
Natural inflation is a well-motivated model for the early universe in which an inflaton potential of the pseudo-Nambu-Goldstone form, , can naturally d…
CMB constraints on inflection-point inflation with a pseudo-scalar dark matter
Jamerson G. Rodrigues, Vinícius Oliveira, Rodrigo von Marttens +2
In this work, we investigate the physical aspects of the inflection-point inflation scenario and assess its observational viability in light of current Cosmic Microwave Background…
Higgs Inflation: constraining the top quark mass and breaking the - correlation
Jamerson G. Rodrigues, Micol Benetti, Rayff de Souza +1
Extending previous results [JHEP 11 (2021) 091], we explore aspects of the reheating mechanism for non-minimal Higgs inflation in the strong coupling regime. We constrain the radia…
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…
Observational constraints on -attractor inflationary models with a Higgs-like potential
J. G. Rodrigues, S. Santos da Costa, J. S. Alcaniz
We investigate the observational viability of a class of -attractors inflationary models in light of the most recent Cosmic Microwave Background (CMB) and Large-Scale Structure…
Probing the Seesaw Mechanism with Cosmological Data
J. G. Rodrigues, Micol Benetti, Marcela Campista +1
We investigate cosmological consequences of an inflationary model which incorporates a generic seesaw extension (types I and II) of the Standard Model of Particle Physics. A non-mi…
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…
Realizing the supersymmetric inverse seesaw model in the framework of R-parity violation
C. A. de S. Pires, J. G. Rodrigues, P. S. Rodrigues da Silva
If, on one hand, the inverse seesaw is the paradigm of TeV scale seesaw mechanism, on the other it is a challenge to find scenarios capable of realizing it. In this work we propose…
