Comment on "Long-range magnetic fields in the ground state of the Standard Model plasma"
Abstract
We revisit the two-loop parity-odd photon polarization analyzed by Boyarsky, Ruchayskiy, and Shaposhnikov [Phys. Rev. Lett. 109, 111602 (2012)]. The original calculation neglected opposite- fermion-flow partner diagrams for the tadpole and exchange-bubble topologies alike. We quantify the impact of the properly restored exchange-bubble coefficients on the static magnetic response.
