Beschreibung:
  • In the dense-neutrino region at 50-400 km above the neutrino sphere in a supernova, neutrino-neutrino interactions cause large flavor transformations. We study when the multi-angle nature of the neutrino trajectories leads to flavor decoherence between different angular modes. We consider a two-flavor mixing scenario between νe and another flavor νx and assume the usual hierarchy Fνe > Fover(ν, -)e > Fνx = Fover(ν, -)x for the number fluxes. © 2009 Elsevier B.V.
