Neutrino Events from Sn1987a Revisited * * *
نویسندگان
چکیده
The e − and e + energy spectra from the SN1987A Supernova neutrino burst interactions are calculated and compared to the observed spectra in Kamiokande-II and IMB experiments. Neutrino oscillations in Supernova and regeneration effects in the Earth, for four combinations of neutrino mass hierarchy (Direct/Inverted) and the value of the mixing angle θ 13 (Large/Small), are taken into account. The influence of the (anti)neutrino production spectra in Supernova on the observed, in Kamiokande-II and IMB detectors, e − /e + spectra is shown.

Statistical analysis of neutrino events from SN1987A neutrino burst: estimation of the electron antineutrino mass
The method of the statistical sample moments was used for the analysis of neutrino events from SN1987A burst in Cherenkov detectors. In particular the coefficients of correlation Q(E, t) between the energies E of electron antineutrinos ν̄e emitted by star and the ejection instants t of ν̄e for neutrino events recorded by Cherenkov water detectors of KII and IMB collaborations were calculated. Q(E...
متن کاملSupernova 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...
متن کاملSupernovæ and Light Neutralinos: SN1987A Bounds on Supersymmetry Revisited
For non-universal gaugino masses, collider experiments do not provide any lower bound on the mass of the lightest neutralino. We review the supersymmetric parameter space which leads to light neutralinos, Mχ̃ ∼ O(1GeV), and find that such neutralinos are almost pure bino. In light of this, we examine the neutralino lower mass bound obtained from supernova 1987A (SN1987A). We consider the product...

We study properties of the oscillation effects in the matter of the Earth on antineu-trino fluxes from supernovae. We show that these effects can provide explanation of the difference in the energy spectra of the events detected by Kamiokande-2 and IMB detectors from SN1987A as well as the absence of high-energy events with E > ∼ 40 MeV. This explanation requires the neutrino oscillation parame...
