Multiple Populations of Same Sterile Neutrino as Dark Matter
Muping Chen, Graciela B. Gelmini, Philip Lu +1
Sterile neutrinos produced in the early Universe that mix with active neutrinos of the Standard Model are typically considered to consist of a single population resulting from one…
Phase Separation Unlocks Resonant Leptogenesis
Jason Arakawa, Philip Lu, Volodymyr Takhistov
Distinct behavior of decaying particles in true and false vacua of the theory can lead to enhanced generation of baryon asymmetry, a scenario we call \textit{phase separation baryo…
Primordial Black Hole Sterile Neutrinogenesis: Sterile Neutrino Dark Matter Production Independent of Couplings
Muping Chen, Graciela B. Gelmini, Philip Lu +1
Sterile neutrinos (s) are well-motivated and actively searched for hypothetical neutral particles that would mix with the Standard Model active neutrinos. They are considered…
Regurgitated Dark Matter
TaeHun Kim, Philip Lu, Danny Marfatia +1
We present a new paradigm for the production of the dark matter (DM) relic abundance based on the evaporation of early Universe primordial black holes (PBHs) themselves formed from…
Note on Thermalization of Non-resonantly Produced Sterile Neutrinos
Graciela B. Gelmini, Philip Lu, Volodymyr Takhistov
Using an analytic treatment, we discuss the parameter regions of large active-sterile neutrino mixing angles where sterile neutrinos produced in non-resonant flavour oscillations c…
Cosmological Dependence of Resonantly Produced Sterile Neutrinos
Graciela B. Gelmini, Philip Lu, Volodymyr Takhistov
The detection of a sterile neutrino could constitute the first observation of a particle that could have been produced before Big-Bang Nucleosynthesis (BBN), and could provide info…
