Abstract Title : Turbulent and Collective Effects on Supernova Neutrinos
|
Abstract :
During core-collapse supernovae explosions, large fluxes of neutrinos are emitted from the proto- neutron star formed at its center. The flavor oscillations of these neutrinos as they pass through the supernova is an area of active study. Previous simulations of neutrino collective effects have found distinct spectral features known as spectral splits but these features may be disrupted by turbulence in the region between the proto-neutron star and the standing accretion shock where the collective effects dominate. We consider this possibility and examine the effect of adding turbulence into several different supernova models under different neutrino mixing schemes and find that turbulence has little effect except for low-mass iron core progenitors and large amplitude turbulence.
