N2 - The well known charge conjugation violating interactions in the standard model increase neutrino- and decrease antineutrino-nucleon cross sections. This impacts neutrino transport in core collapse supernovae through “recoil” corrections of order the neutrino energy k over the nucleon mass M. All (Formula presented) corrections to neutrino transport deep inside a protoneutron star are calculated from angular integrals of the Boltzmann equation. We find these corrections significantly modify neutrino currents at high temperatures. This produces a large mu and tau number for the protoneutron star and can change the ratio of neutrons to protons. In addition, the relative size of neutrino mean free paths changes at high temperatures.
