Trimers in the Extended Hubbard Model
R. R. Montenegro-Filho, D. R. B. Silva, D. Cogollo +1
The Lieb theorem is a cornerstone of quantum magnetism theory in condensed matter. In this work, we investigate the instability of the Lieb insulating ferrimagnetic phase in the ex…
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…
Search for sub-GeV Scalars in collisions
D. Cogollo, Y. M. Oviedo-Torres, Farinaldo S. Queiroz +2
Light scalars that couple to leptons are common figures in beyond the Standard Model endeavors. Considering a scalar that has universal and couplings to leptons only, we compute th…
Constraints on Hidden Sectors Using Rare Kaon Decays
D. Cogollo, M. J. Neves, Tessio B. de Melo +3
The charged Kaon meson () features several hadronic decay modes, but the most relevant contribution to its decay width stems from the leptonic decay .…
Naturally low scale type I seesaw mechanism and its viability in the 3-3-1 model with right-handed neutrinos
E. Cabrera, D. Cogollo, C. A. de S. Pires
Seesaw mechanisms are the simplest and the most elegant way of generating small masses for the active neutrinos . In these mechanisms is inversely proportional to the…
Deep learnig analysis of the inverse seesaw in a 3-3-1 model at the LHC
D. Cogollo, F. F. Freitas, C. A. de S. Pires +2
Inverse seesaw is a genuine TeV scale seesaw mechanism. In it active neutrinos with masses at eV scale requires lepton number be explicitly violated at keV scale and the existence…
