1104.3106 (V. B. Semikoz et al.)

Chern-Simons anomaly as polarization effect    [PDF]

V. B. Semikoz, J. W. F. Valle
The parity violating Chern-Simons term in the epoch before the electroweak phase transition can be interpreted as a polarization effect associated to massless right-handed electrons (positrons) in the presence of a large-scale seed hypermagnetic field. We reconfirm the viability of a unified seed field scenario relating the cosmological baryon asymmetry and the origin of the protogalactic large-scale magnetic fields observed in astronomy.
