Optical activity of relic neutrino-antineutrino gas

We revise a problem of the birefringence of electromagnetic waves in a chiral medium in the Standard Model (SM) of particle physics arising in an isotropic plasma due to parity violation. The recent calculations of the weak correction to the photon polarization operator in electroweak plasma allow significantly to improve some previous estimates of such effect in astrophysics. Nevertheless, it has remained beyond the abilities of the present technics yet.
