Lepton flavor asymmetries: from the early Universe to BBN

Lepton flavor asymmetries: from the early Universe to BBN

Abstract Large primordial lepton flavor asymmetries with almost vanishing total baryon-minus-lepton number can evade the usual BBN and CMB constraints if neutrino oscillations lead to perfect flavor equilibration. Solving the momentum averaged quantum kinetic equations (QKEs) describing neutrino osc...
