Neutrino Cloud Instabilities Just above the Neutrino Sphere of a Supernova.

摘要: Most treatments of neutrino flavor evolution, above a surface the last scattering, take identical angular distributions on this for different initial (unmixed) flavors, and particles antiparticles. Differences in these must be present, as result species-dependent scattering cross sections lower star. These lead to new set nonlinear equations, unstable even at with respect perturbations that break all-over spherical symmetry. There could important consequences explosion dynamics well pulse outer regions.
