Models with two Higgs doublets and a light pseudoscalar:a portal to dark matter and the possible excess
Giorgio Arcadi, Abdelhak Djouadi, Farinaldo Queiroz
In the context of a two-Higgs doublet model, supplemented by an additional light pseudoscalar Higgs boson and a stable isosinglet fermion, we consider the possibility of addressing…
Roads for Right-handed Neutrino Dark Matter: Fast Expansion, Standard Freeze-out, and Early Matter Domination
Giorgio Arcadi, Jacinto Paulo Neto, Farinaldo S. Queiroz +1
Right-handed neutrinos appear in several extensions beyond the Standard Model, specially in connection to neutrino masses. Motivated by this, we present a model of right-handed neu…
Indirect Searches for Secluded Dark Matter
C. Siqueira, Guilherme N. Fortes, Aion Viana +1
Dark matter is one of the most important open problems in particle physics and cosmology. Weakly interacting massive particles (WIMPs) appear as an appealing solution, providing th…
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 model for mixed warm and hot right-handed neutrino dark matter
Maíra Dutra, Vinícius Oliveira, C. A. de S. Pires +1
We discuss a model where a mixed warm and hot keV neutrino dark matter rises naturally. We arrange active and sterile neutrinos in the same multiplet, with the lightest s…
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…
Detecting Bosonic Dark Matter with Neutron Stars
Tarak Nath Maity, Farinaldo S Queiroz
What if the dark matter-nucleon scattering cross section is too small to be detected by direct detection experiments? It is well known in the literature that some interactions lead…
Probing the Anomaly at a Muon Collider
Guo-yuan Huang, Sudip Jana, Farinaldo S. Queiroz +1
The LHCb measurements of the ratio in decays indicate a deficit with respect to the Standard Model prediction, supporting earlier hints of l…
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…
Gauged at a muon collider
Guo-yuan Huang, Farinaldo S. Queiroz, Werner Rodejohann
We investigate the sensitivity of the projected TeV muon collider to the gauged - model. Two processes are considered: -mediated two-body scatterings $μ^+ μ^- \…
Scalar Multiplet Dark Matter in a Fast Expanding Universe: resurrection of the desert region
Basabendu Barman, Purusottam Ghosh, Farinaldo S. Queiroz +1
We examine the impact of a faster expanding Universe on the phenomenology of scalar dark matter (DM) associated with multiplets. Earlier works with radiation dominated Un…
