Big Bang Nucleosynthesis and Cosmological Constraints on Neutrino Oscillation Parameters
Daniela Kirilova, Mihail Chizhov
We present a review of cosmological nucleosynthesis (CN) with neutrino oscillations, discussing the different effects of oscillations on CN, namely: increase of the effective degre…

On Neutrino-Mixing-Generated Lepton Asymmetry and the Primordial Helium-4 Abundance
M. V. Chizhov, D. P. Kirilova
In this article we discuss lepton asymmetry effect on BBN with neutrino oscillations. We argue that asymmetry much smaller than 0.01, although not big enough to influence directly…

Nonequilibium Neutrino Oscillations and Primordial Nucleosynthesis
D. P. Kirilova, M. V. Chizhov
We studied nonequilibrium oscillations between left-handed electron neutrinos and nonthermalized sterile neutrinos. The exact kinetic equations for neutrinos, written in terms of n…
