Inflation, (p)reheating and neutrino anomalies: production of sterile neutrinos with secret interactions
Abstract A number of experimental anomalies involving neutrinos hint towards the existence of at least an extra (a very light) sterile neutrino. However, such a species, appreciably mixing with the active neutrinos, is disfavored by different cosmological observations like Big Bang Nucleosynthesis (...
