CUMULATIVE PARITY VIOLATION IN SUPERNOVAE

Supernovae provide a unique opportunity for large scale parity violati on because they are dominated by neutrinos. We calculate the parity vi olating asymmetry A of neutrino emission in a strong magnetic field. W e assume the neutrinos elastically scatter many times from slightly po larized neutrons. Because of the multiple interactions, A grows with t he optical thickness of the protoneutron star and may be much larger t han previous estimates. As a result, the neutron star could recoil at a significant velocity.
