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…
anomalies and muon from Dark Matter
Giorgio Arcadi, Lorenzo Calibbi, Marco Fedele +1
Motivated by the result of the Muon g-2 experiment and the long-standing anomalies in semileptonic meson decays, we systematically build a class of minimal models that can addr…
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…
Muon and -anomalies from Dark Matter
Giorgio Arcadi, Lorenzo Calibbi, Marco Fedele +1
In the light of the recent result of the Muon g-2 experiment and the update on the test of lepton flavour universality published by the LHCb collaboration, we systematically…
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…
Systematic approach to -physics anomalies and -channel dark matter
Giorgio Arcadi, Lorenzo Calibbi, Marco Fedele +1
We study renormalisable models with minimal field content that can provide a viable Dark Matter candidate through the standard freeze-out paradigm and, simultaneously, accommodate…
