Resurrection of large lepton number asymmetries from neutrino flavor oscillations

arXiv:1609.01584 · doi:10.1103/PhysRevD.95.043506

Abstract

We numerically solve the evolution equations of neutrino three-flavor density matrices, and show that, even if neutrino oscillations mix neutrino flavors, large lepton number asymmetries are still allowed in certain limits by Big Bang Nucleosynthesis (BBN).
