Determining neutrino and supernova parameters with a galactic supernova [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2007
We investigate the sensitivity of some of the proposed next-generation neutrino experiments to a galactic supernova. In particular, we study how well the supernova parameters (the average energies and luminosities) can be separated from the unknown neutrino oscillation parameters ($θ_{13}$ and the neutrino mass hierarchy).

Decoherence and oscillations of supernova neutrinos [PDF]

open access: yes, 2015
Supernova neutrinos have several exceptional features which can lead to interesting physical consequences. At the production point their wave packets have an extremely small size $$\sigma _{x} \sim 10^{-11}$$σx∼10-11 cm; hence the energy uncertainty can ...

Detection of Supernova Neutrinos

open access: yes, 2004
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.

Highlight Talk from Super-Kamiokande

open access: yesUniverse, 2019
Super-Kamiokande (SK), a 50 kton water Cherenkov detector in Japan, is observing both atmospheric and solar neutrinos. It is also searching for supernova (relic) neutrinos, proton decays and dark matter-like particles. A three-flavor oscillation analysis

Examining Neutrino–Matter Interactions in the Cassiopeia A Supernova

open access: yesThe Astrophysical Journal, 2023
Neutrino interactions with stellar material are widely believed to be fundamental to the explosion of massive stars. However, this important process has remained difficult to confirm observationally.

Self-induced flavor conversion of supernova neutrinos on small scales [PDF]

open access: yes, 2015
Self-induced flavor conversion of supernova (SN) neutrinos is a generic feature of neutrino-neutrino dispersion. The corresponding run-away modes in flavor space can spontaneously break the original symmetries of the neutrino flux and in particular can ...

SNEWPY: A Data Pipeline from Supernova Simulations to Neutrino Signals

open access: yesThe Astrophysical Journal, 2022
Current neutrino detectors will observe hundreds to thousands of neutrinos from Galactic supernovae, and future detectors will increase this yield by an order of magnitude or more.

Entangled neutrinos in a supernova

open access: yes, 2022
A Life in Mathematical Physics: Conference in Honour of Tekin Dereli, DERELI-FS 2021 -- 26 November 2021 through 28 November 2021 -- Virtual, Online -- 177155We consider the entanglement of neutrinos evolving adiabatically under the effect of vacuum ...

Neutrino flavor instabilities in a time-dependent supernova model

open access: yesPhysics Letters B, 2015
A dense neutrino medium such as that inside a core-collapse supernova can experience collective flavor conversion or oscillations because of the neutral-current weak interaction among the neutrinos.

Supernova neutrino burst detection with the deep underground neutrino experiment

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
The deep underground neutrino experiment (DUNE), a 40-kton underground liquid argon time projection chamber experiment, will be sensitive to the electron-neutrino flavor component of the burst of neutrinos expected from the next Galactic core-collapse ...
