Query: Photon neutrino scattering   The cross section for photon neutrino scattering is calculated in the
standard model assuming that the neutrino is massless and that the center of
mass energy is small compared to any charged lepton mass. Although the
scattered photons can acquire a (parity violating) circular polarization of
order unity, the cross section in this limit is highly suppressed.
