Supernova Neutrinos
A nascent neutron star resulting from stellar collapse is a prodigious source of neutrinos of all flavors. While the most basic features of this neutrino emission can be estimated from simple considerations, the detailed simulation of the neutrinos’ decoupling from the hot neutron star is not yet computationally tractable in its full glory, being a time-dependent six-dimensional transport probl...
متن کاملSupernova Neutrinos, Lsnd and Miniboone
The unique constraints on neutrino oscillations which can be obtained by measuring the energy spectrum of supernova ν̄e’s are first discussed. The focus is on 4-neutrino mass and mixing models capable of explaining the LSND evidence of ν̄μ → ν̄e oscillations. The potential of the Fermilab neutrino detector MiniBooNE to observe supernova neutrinos is then addressed, and a general description of the...
متن کاملDecays of supernova neutrinos
Supernova neutrinos could be well-suited for probing neutrino decay, since decay may be observed even for very small decay rates or coupling constants. We will use a combined description of neutrino decay and neutrino oscillations for supernova neutrinos, especially taking into account two properties: One is the radially symmetric neutrino flux, allowing a decay product to be re-directed toward...
متن کاملSterile Neutrinos and Supernova Nucleosynthesis
A light sterile neutrino species has been introduced to explain simultaneously the solar and atmospheric neutrino puzzles and the results of the LSND experiment, while providing for a hot component of dark matter. Employing this scheme of neutrino masses and mixings, we show how matter-enhanced active-sterile (νμ,τ ⇀↽ νs) neutrino transformation followed by active-active (νμ,τ ⇀↽ νe) neutrino t...
متن کاملDetection of Supernova Neutrinos * * *
Matter effects on neutrino oscillations in both, a supernova and the Earth, change the observed supernova neutrino spectra. We calculate the expected number of supernova neutrino interactions for ICARUS, SK and SNO detectors as a function of the distance which they traveled in the Earth. Calculations are performed for supernova type II at 10 kpc from the Earth, using standard supernova neutrino...
