Neutrino Oscillations and Their Origin, 2002
We propose that neutrino-proton elastic scattering, {nu} + p {yields} {nu} + p, can be used for the detection of supernova neutrinos. Though the proton recoil kinetic energy spectrum is soft, with T{sub p} {approx_equal} 2E{sub {nu}}{sup 2}/M{sub p}, and the scintillation light output from slow, heavily ionizing protons is quenched, the yield above a ...

Supernova neutrinos and their oscillations
Physical Review D, 1988Three-neutrino oscillations, both in a vacuum and in matter, are applied to the supernova neutrino flux. It is found that oscillations can change the flux substantially, reducing the number of directional events in the Kamioka nucleon-decay experiment and increasing the number of isotropic events in the Irvine-Michigan-Brookhaven experiment.

Turbulence and supernova neutrinos
2010As neutrinos propagate from the neutrinosphere through the mantle of a core-collapse supernova they will pass through regions of turbulence. The turbulence leads to stochastic neutrino flavor mixing thus leaving fingerprints in the Galactic supernova neutrino burst signal. In this talk I explore the effect of turbulence upon the neutrinos focusing upon

Core‐collapse supernovae are one of the few astrophysical environments in which neutrinos play a dominant role. Neutrinos emission is the means by which a newly‐born neutron star formed in a core‐collapse event cools. Neutrinos may play a significant role in causing the supernova explosion. Finally neutrinos may significantly affect the nucleosynthesis

Neutrino Heating in Supernovae
Physical Review Letters, 1988I argue that standard descriptions of stellar collapse omit the primary mechanism for dissipative neutrino reactions in nuclear matter, nuclear excitation by neutral-current scattering. The nuclear heating rate, due to primarily to muon- and tauon-neutrino excitation of giant resonance states, is on the order of 90 MeV/nucleon sec at a radius of 100 km.

SUPERNOVA EXPLOSIONS AND SUPERNOVA NEUTRINOS
Neutrinos in Physics and Astrophysics, 2000We summarize the current status of core-collapse supernova theory, in particular as it relates to multi-dimensional effects and neutrino transport . Highlighted are pulsar kicks , neutrino burst signatures, many-body effects, and observed asphericities that may have a bearing on the mechanism of supernova explosions .

Physics Reports, 1988
Abstract The role of neutrinos in Type II supernovae is discussed. An overall view of the neutrino luminosity as expected theoretically is presented. The different weak interactions involved are assessed from the standpoint of how they exchange energy, momentum, and lepton number.

The future of supernova neutrino detection
Physical Review D, 1992By a series of independent decisions, an international network of massive underground neutrino detectors is being established whose collective sensitivity to supernova neutrinos will be unprecedented. Individually and in coordinated fashion, these detectors could provide temporal, energetic, angular, and flavor information for any stellar collapse in ...
