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…
Vector-Like Fermions and Inert Scalar Solutions to the Muon g-2 Anomaly and collider probes at the HL-LHC and FCC-hh
Á. S. de Jesus, F. S. Queiroz, J. W. F. Valle +1
We examine simple models with an inert scalar and vector-like leptons that can explain the recent measurement reported at FNAL. Prompted by this exciting result, we explore…
Updated Big Bang Nucleosynthesis Bounds on Long-lived Particles from Dark Sectors
J. R. Alves, L. Angel, L. Guedes +5
As electromagnetic showers may alter the abundance of Helium, Lithium, and Deuterium, we can place severe constraints on the lifetime and amount of electromagnetic energy injected…
Toward a search for axion-like particles at the LNLS
L. Angel, P. Arias, C. O. Dib +8
Axion-Like Particles (ALPs) appear in several dark sector studies. They have gained increasing attention from the theoretical and experimental community. In this work, we propose t…
On the Role of LHC and HL-LHC in Constraining Flavor Changing Neutral Currents
S. Kovalenko, A. S. de Jesus, A. R. Zerwekh +5
The Standard Model (SM) has no flavor-changing neutral current (FCNC) processes at the tree level. Therefore, processes featuring FCNC in new physics are tightly constrained by dat…
Flavor changing interactions confronted with meson mixing and hadron colliders
A. E. Cárcamo Hernández, L. Duarte, A. S. de Jesus +5
We have witnessed some flavor anomalies appeared in the past years, and explanations based on extended gauge sectors are among the most popular solutions. These beyond the Standard…
Search for Dark Sector by Repurposing the UVX Brazilian Synchrotron
L. Duarte, L. Lin, M. Lindner +6
We propose the first Search for Dark Sector at the Brazilian Synchrotron Light Laboratory, site of Sirius, a fourth-generation storage ring. We show that UVX, Sirius predecessor, c…
Constraining 3-3-1 Models at the LHC and Future Hadron Colliders
A. Alves, L. Duarte, S. Kovalenko +3
In this work, we derive lower mass bounds on the Z' gauge boson based on the dilepton data from LHC with 13 TeV of center-of-mass energy, and forecast the sensitivity of the High-L…
Confronting the inverse seesaw mechanism with the recent muon g-2 result
João Paulo Pinheiro, C. A. de S. Pires, Farinaldo S. Queiroz +1
Since the heavy neutrinos of the inverse seesaw mechanism mix largely with the standard ones, the charged currents formed with them and the muons have the potential of generating r…
An extended 3-3-1 model with radiative linear seesaw mechanism
A. E. Cárcamo Hernández, Sergey Kovalenko, Farinaldo S. Queiroz +1
Motivated by the recent muon anomalous magnetic moment (g-2) measurement at FERMILAB and non-zero neutrino masses, we propose a model based on the $SU(3)_C \times SU(3)_L \times U(…
A 2HDM for the g-2 and Dark Matter
Giorgio Arcadi, Álvaro S. de Jesus, Téssio B. de Melo +2
The Muon g-2 experiment at FERMILAB has confirmed the muon anomalous magnetic moment anomaly with an error bar 15% smaller and a different central value compared with the previous…
Rare Kaon Decay to Missing Energy: Implications of the NA62 Result for a Model
Téssio B. de Melo, Sergey Kovalenko, Farinaldo S. Queiroz +2
Meson decays offer a good opportunity to probe new physics. The rare kaon decay is one of the cleanest of them and, for this reason, is rather sensitiv…
Are 3-4-1 models able to explain the upcoming results of the muon anomalous magnetic moment?
D. Cogollo, Yohan M. Oviedo-Torres, Yoxara S. Villamizar
In light of the upcoming measurement of the muon anomalous magnetic moment (g-2), we revisit the corrections to g-2 in the context of the gauge symmetry. We…
Dead or Alive? Implications of the Muon Anomalous Magnetic Moment for 3-3-1 Models
Alvaro S. de Jesus, Sergey Kovalenko, Farinaldo S. Queiroz +2
We have witnessed a persistent puzzling anomaly in the muon magnetic moment that cannot be accounted for in the Standard Model even considering the large hadronic uncertainties. A…
Doubly Charged Scalar at the High-Luminosity and High-Energy LHC
Tessio B. de Melo, Farinaldo S. Queiroz, Yoxara Villamizar
Doubly charged scalars are common figures in several beyond the Standard Model studies, especially those related to neutrino masses. In this work, we estimate the High-Luminosity (…
