Cosmological chirality and magnetic fields from parity violating particle decays
arXiv:2101.06344 · doi:10.1103/PhysRevD.103.103528
Abstract
We estimate the chirality of the cosmological medium due to parity violating decays of standard model particles, focusing on the example of tau leptons. The non-trivial chirality is however too small to make a significant contribution to the cosmological magnetic field via the chiral-magnetic effect.
