We calculate the yield of such g events and estimate that a few hundred of them would be detected in Superkamiokande for a supernova at 10 kpc distance.

Mass signature of supernova nμ and nt neutrinos in SuperKamiokande
The nm and nt neutrinos ~and their antiparticles! from a Galactic core-collapse supernova can be observed in a water-Čerenkov detector by the neutral-current excitation of O. The number of events expected is several times greater than from neutral-current scattering on electrons. The observation of this signal would be a strong test that these neutrinos are produced in core-collapse supernovae,...
متن کاملDetection of supernova neutrinos by neutrino-proton elastic scattering
We propose that neutrino-proton elastic scattering, n1p→n1p , can be used for the detection of supernova neutrinos in scintillator detectors. Though the proton recoil kinetic energy spectrum is soft, with Tp .2En /M p , and the scintillation light output from slow, heavily ionizing protons is quenched, the yield above a realistic threshold is nearly as large as that from n̄e1p→e1n . In addition,...

We suggest that photons with energies between 5 and 10 MeV, generated by the (ν, ν pγ) and (ν, ν nγ) reactions on O, constitute a signal which allows a unique identification of supernova νμ and ντ neutrinos in water Čerenkov detectors.

متن کاملTurbulent Supernova Shock Waves and the Sterile Neutrino Signature in Megaton Water Detectors
The signatures of sterile neutrinos in the supernova neutrino signal in megaton water Cerenkov detectors are studied. Time dependent modulation of the neutrino signal emerging from the sharp changes in the oscillation probability due to shock waves is shown to be a smoking gun for the existence of sterile neutrinos. These modulations and indeed the entire neutrino oscillation signal is found to...
متن کاملThe Supernova Early Warning System
A core collapse in the Milky Way will produce an enormous burst of neutrinos in detectors worldwide. Such a burst has the potential to provide an early warning of a supernova's appearance. I will describe the nature of the signal, the sensitivity of current detectors, and SNEWS, the SuperNova Early Warning System, a network designed to alert astronomers as soon as possible after the detected ne...
