Self-Consistent Evolution of Magnetic Fields and Chiral Asymmetry in the Early Universe
Self-Consistent Evolution of Magnetic Fields and Chiral Asymmetry in the Early Universe
We show that the evolution of magnetic fields in a primordial plasma, filled with Standard Model particles, at temperatures T > 10 MeV is strongly affected by the quantum chiral anomaly -- an effect that has been neglected previously. Although reactions equilibrating left and right-chiral electrons are in deep thermal …
