Standard Model Neutrinos as Warm Dark Matter
Gian F. Giudice, Edward W. Kolb, Antonio Riotto +2
Standard Model neutrinos are not usually considered plausible dark matter candidates because the usual treatment of their decoupling in the early universe implies that their mass m…
Maximum lepton asymmetry from active-sterile neutrino oscillations in the Early Universe
R. Buras, D. V. Semikoz
A large lepton asymmetry could be generated in the Early Universe by oscillations of active to sterile neutrinos with a small mixing angle sin 2 θ< 10^-2. The final order of magnit…
Heavy sterile neutrinos: Bounds from big-bang nucleosynthesis and SN 1987A
A. D. Dolgov, S. H. Hansen, G. Raffelt +1
Cosmological and astrophysical effects of heavy (10 - 200 MeV) sterile Dirac neutrinos, mixed with the active ones, are considered. The bounds on mass and mixing angle from both su…
Cosmological and astrophysical bounds on a heavy sterile neutrino and the KARMEN anomaly
A. D. Dolgov, S. H. Hansen, G. Raffelt +1
Constraints on the lifetime of the heavy sterile neutrino, that was proposed as a possible interpretation of the KARMEN anomaly, are derived from primordial nucleosynthesis and SN…
