Description
Recent precise measurements of the primordially produced D and He-4 allowed us to update the BBN constraints on electron-sterile neutrino oscillations parameters. We discuss lepton asymmetry - neutrino oscillations interplay and derive cosmological constraints on lepton asymmetry. We discuss a solution to the dark radiation (DR) problem in BBN models with electron-sterile neutrino oscillations. We find that the required lepton asymmetry value for solving DR problem is
close to the value indicated by the EMPRESS experiment.
