Abstract The total lepton asymmetry l = ∑ f l f in our universe is only poorly constrained by theories and experiments. It might be orders of magnitudes larger than the observed baryon asymmetry b ≃ O ( 1 0 − 10 ) , | l | / b ≤ O ( 10 9 ) . We found that the dynamics of the cosmic QCD transition changes for large asymmetries. Predictions for asymmetries in a single flavour l f allow even larger values. We find that asymmetries of l f ≤ O ( 1 ) in single or two flavours may change the relic… Expand

TLDR
A potentially observable neutrino asymmetry is correlated with a baryon asymmetry of the order of 10(-10) and the ratio n(L)/n(B) is naturally in the range 10(8)-10(9). Expand
Constraining the universal lepton asymmetry
The relic cosmic background neutrinos accompanying the cosmic microwave background (CMB) photons may hide a universal lepton asymmetry orders of magnitude larger than the universal baryon asymmetry.Expand
Generation of large lepton asymmetries
Abstract We present here a realistic model to produce a very large lepton asymmetry L ⋍ 10 −2 −1 , without producing a large baryon asymmetry. The model is based on the Affleck and Dine scenario, inExpand
Relic density of neutrinos with primordial asymmetries.
TLDR
The degree of flavor equilibration among neutrinos and with the ambient plasma is estimated for the first time, and the restrictive big-bang nucleosynthesis bound on the nu_{e}nu[over]_{e] asymmetry indeed applies to all flavors. Expand
