Freeze-in leptogenesis with 3 right-handed neutrinos
Michele Lucente, Asmaa Abada, Giorgio Arcadi +3
We provide the first systematic study of the viable parameter space for leptogenesis in the type-I seesaw model with three right-handed neutrinos whose Majorana masses lie below th…
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…
Low-scale leptogenesis with three heavy neutrinos
Asmaa Abada, Giorgio Arcadi, Valerie Domcke +3
Leptogenesis induced by the oscillations of GeV-scale neutrinos provides a minimal and testable explanation of the baryon asymmetry of the Universe. In this work we extend previous…
Coherent scattering and macroscopic coherence: Implications for neutrino, dark matter and axion detection
Evgeny Akhmedov, Giorgio Arcadi, Manfred Lindner +1
We study the question of whether coherent neutrino scattering can occur on macroscopic scales, leading to a significant increase of the detection cross section. We concentrate on r…
2HDM portal for Singlet-Doublet Dark Matter
Giorgio Arcadi
We present an extensive analysis of a model in which the (Majorana) Dark Matter candidate is a mixture between a SU(2) singlet and two SU(2) doublets. This kind of setup takes the…
Leptogenesis, dark matter and neutrino masses
Michele Lucente, Asmaa Abada, Giorgio Arcadi +1
We review the viability of the sterile neutrino hypothesis in accounting for three observational problems of the Standard Model of particle physics: neutrino masses and lepton mixi…
