MeV-scale reheating temperature and cosmological production of light sterile neutrinos
Takuya Hasegawa, Nagisa Hiroshima, Kazunori Kohri +3
We investigate how sterile neutrinos with a range of masses influence cosmology in MeV-scale reheating temperature scenarios. By computing the production of sterile neutrinos throu…
MeV-scale reheating temperature and thermalization of oscillating neutrinos by radiative and hadronic decays of massive particles
Takuya Hasegawa, Nagisa Hiroshima, Kazunori Kohri +3
From a theoretical point of view, there is a strong motivation to consider an MeV-scale reheating temperature induced by long-lived massive particles with masses around the weak sc…
Active-sterile neutrino oscillations in the early Universe with full collision terms
Steen Hannestad, Rasmus Sloth Hansen, Thomas Tram +1
Sterile neutrinos are thermalised in the early Universe via oscillations with the active neutrinos for certain mixing parameters. The most detailed calculation of this thermalisati…
