Supernova neutrinos

by Petr Vogel - X International Workshop on Neutrino Telescopes , 2003
"... I describe how the signals corresponding to the supernova νe and ¯νe (charged current reactions) as well as all active neutrinos (neutral current reactions) can be separately observed in various existing detectors. These observations would make it possible to determine the flux and average energy (o ..."

NEUTRONIZATION NEUTRINO PULSES FROM SUPERNOVAE AND THE TRIPLET MAJORON MODEL

by Y. Aharonov, F. T. Avignone Iii, S. Nussinov , 1987
"... We address a possible implication of the triplet majoron (TM) model for neutrino pulses from supernovae. If the v~v~-majoron coupling is ~ 0.7 X 10-3, suggested by one of the recent ~13-decay experiments, equilibration of v-species via v~v~--.%v,(v~v~), occurs on a time scale ~ 10-4 s. Rapid equilib ..."

equilibration followed by decay in flight via v(v~)--.9 ~ +X °, could dramatically enhance the probability of observing neutronization neutrinos, even for g ~ ~ ~ 10-is. This effect would make nearby supernovae sensitive tests of TM models. A millisecond "neutronization " pulse of v e is pre

1 Supernova Neutrino Detection

by Kate Scholberg A , 2000
"... World-wide, several detectors currently running or nearing completion are sensitive to a core collapse supernova neutrino signal in the Galaxy. I will briefly describe the nature of the neutrino signal and then survey current and future detection techniques. I will also explore what physics and astr ..."

ASPECTS OF NEUTRINO PRODUCTION IN SUPERNOVAE

by Todd A. Thompson , 2006
"... I discuss neutrino production in supernovae (SNe) and the detection of both Galactic core collapse events and the diffuse extra-galactic MeV neutrino background expected from the integrated history of star formation. In particular, I consider what processes might affect our expectations for both. I ..."

Supernova neutrino detection in Borexino

by L. Cadonati, F. P. Calaprice, M. C. Chen - Astropart. Phys
"... We calculated the expected neutrino signal in Borexino from a typical Type II supernova at a distance of 10kpc. A burst of around 110 events would appear in Borexino within a time interval of about 10s. Most of these events would come from the reaction channel ¯νe + p → e + + n, while about 30 event ..."

SOLAR AND Supernovae NEUTRINOS

by Daniel Vignaud
"... Neutrinos have been and are abundantly produced in the Universe and neutrino astronomy provides very rich information either in astrophysics or in particle physics. We focus in this review on neutrinos as witnesses of the life of stars (solar neutrinos) and on neutrinos as messengers of the death of ..."

Supernova neutrinos

by C. Y. Cardall Ab , 2007
"... 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 c ..."

Prospects for detecting supernova neutrino oscillations

by George M. Fuller, Wick C. Haxton, Gail C. Mclaughlin - Phys. Rev. D , 1999
"... The neutrinos from a Type II supernova provide perhaps our best opportunity to probe cosmologically interesting muon and/or tauon neutrino masses. This is because matter enhanced neutrino oscillations can lead to an anomalously hot νe spectrum, and thus to enhanced charged current cross sections in ..."

in terrestrial detectors. Two recently proposed supernova neutrino observatories, OMNIS and LAND, will detect neutrons spalled from target nuclei by neutral and charged current neutrino interactions. As this signal is not flavor specific, it is not immediately clear whether a convincing neutrino oscillation
