Tritium beta decay with additional emission of new light bosons
Giorgio Arcadi, Julian Heeck, Florian Heizmann +5
We consider tritium beta decay with additional emission of light pseudoscalar or vector bosons coupling to electrons or neutrinos. The electron energy spectrum for all cases is eva…
Neutrino Masses in a Two Higgs Doublet Model with a U(1) Gauge Symmetry
Daniel A. Camargo, Alex G. Dias, Tessio B. de Melo +1
General Two Higgs Doublet Models (2HDM) are popular Standard Model extensions but feature flavor changing interactions and lack neutrino masses. We discuss a 2HDM where neutrino ma…
Gamma-ray lines may reveal the CP nature of the dark matter particle
Farinaldo S. Queiroz, Carlos E. Yaguna
Determining the fundamental properties of the dark matter is one of the most important open problems in particle physics today. If the dark matter particle has spin zero, one of th…
Scrutinizing Right-Handed Neutrino Portal Dark Matter With Yukawa Effect
Priyotosh Bandyopadhyay, Eung Jin Chun, Rusa Mandal +1
Analyzing the neutrino Yukawa effect in the freeze-out process of a generic dark matter candidate with right-handed neutrino portal, we identify the parameter regions satisfying th…
Asymmetric Dark Matter, Inflation and Leptogenesis from B-L Symmetry Breaking
P. V. Dong, D. T. Huong, Daniel A. Camargo +2
We propose a unified setup for dark matter, inflation and baryon asymmetry generation through the neutrino mass seesaw mechanism. Our scenario emerges naturally from an extended ga…
Collider Bounds on 2-Higgs Doublet Models with Gauge Symmetries
Daniel A. Camargo, Luigi Delle Rose, Stefano Moretti +1
2-Higgs Doublet Models (2HDMs) typically need to invoke an ad-hoc discrete symmetry to avoid severe flavor bounds and in addition feature massless neutrinos, thus falling short of…
XENON1T Takes a Razor to a Dark -Inspired Model
Daniel A. Camargo, Yann Mambrini, Farinaldo S. Queiroz
Motivated by the recent result of XENON1T collaboration with full exposure, 279 life days, that sets the most stringent limit on the spin-independent dark matter-nucleon scattering…
The Dark Rises via Kinetic Mixing
Giorgio Arcadi, Thomas Hugle, Farinaldo S. Queiroz
We investigate the dark matter phenomenology of a Dirac fermion together with kinetic mixing in the context of an model. We analyze which part of the parameter space can…
Neutrino-Electron Scattering: General Constraints on Z' and Dark Photon Models
Manfred Lindner, Farinaldo S. Queiroz, Werner Rodejohann +1
We study the framework of models with kinetic mixing and/or mass mixing terms. We give general and exact analytic formulas and derive limits on a variety of model…
MeV Dark Matter Complementarity and the Dark Photon Portal
Maíra Dutra, Manfred Lindner, Stefano Profumo +3
We discuss the phenomenology of an MeV-scale Dirac fermion coupled to the Standard Model through a dark photon with kinetic mixing with the electromagnetic field. We compute the da…
