Self-induced suppression of collective neutrino oscillations in a supernova.

We investigate collective flavor oscillations of supernova neutrinos at late stages of the explosion. We first show that the frequently used single-angle (averaged coupling) approximation predicts oscillations close to, or perhaps even inside, the neutrinosphere, potentially invalidating the basic neutrino transport paradigm. Fortunately, we also find that the single-angle approximation breaks ...

Neutral current induced neutrino oscillations in a supernova

Neutral currents induced matter oscillations of electroweak-active (anti-)neutrinos to sterile neutrinos can explain the observed motion of pulsars. In contrast to a recently proposed explanation of the pulsar birth velocities based on the νμ,τ ↔ νe oscillations, the heaviest neutrino (either active or sterile) would have to have mass of order several keV. ∗ email address: [email protected] ...

Prospects for Detecting Supernova Neutrino Flavor Oscillations

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 terrestrial detectors. Two recently proposed supernova neutrino observatories, OMNIS and LAND, wi...

Supernova neutrino fluxes from the LSD neutrino signal from SN1987A

Detection of 5 events by the Liquid Scintillation Detector (LSD) on February, 23, 1987 was recently interpreted as a detection of the electron neutrino flux from the first stage of the two-stage Supernova collapse [1][2]. We show that, if neutrino mass hierarchy is normal, such interpretation excludes values of neutrino mixing angle θ13 larger than 3 · 10 , independently of the particular Super...

Supernova neutrino oscillations: what do we understand?

We summarize our current understanding of the neutrino flavor conversions inside a core collapse supernova, clarifying the important role played by the “collective effects” in determining flavor conversion probabilities. The potentially observable νe and ν̄e spectra may help us identify the neutrino mixing scenario, distinguish between primary flux models, and learn more about the supernova expl...
