Abstract
We calculate neutrino and antineutrino scattering off electrons and nucleons in supernovae using a detailed Monte Carlo transport code incorporating realistic equations of state. The goal is to determine whether particles in a neutron star core, partially spin-aligned by the local magnetic field, can give rise to asymmetric neutrino emission via the standard parity breaking weak force. We conclude that electron scattering in a very high magnetic field does indeed give a net asymmetry, but that nucleon scattering, if present, removes the asymmetry.
