Solar Neutrinos: Interpretation of Results
Recent SNO results give strong evidence that the solar neutrinos undergo the flavor conversion. Main issue now is the identification of the mechanism of conversion. The LMA MSW solution with ∆m = (5−7) ·10 eV, tan θ = 0.35−0.45 looks rather plausible: it fits well the experimental data and our new theoretical prejudices. In the LMA case, KamLAND should see (0.5 0.7) reduced signal. VAC-QVO and ...
متن کاملDetection of Supernova Neutrinos * * *
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. Calculations are performed for supernova type II at 10 kpc from the Earth, using standard supernova neutrino...
متن کاملNeutrinos from SN1987A: flavor conversion and interpretation of results
After recent results from solar neutrino experiments and KamLAND we can definitely say that neutrinos from SN1987A underwent flavor conversion, and the conversion effects must be taken into account in the analysis of the data. Assuming the normal mass hierarchy of neutrinos we calculate the permutation factors p for the Kamiokande-2, IMB and Baksan detectors. The conversion inside the star lead...
متن کاملExtremely High Energy Neutrinos and Their Detection
We discuss in some detail the production of extremely high energy (EHE) neutrinos with energies above 1018 eV. The most certain process for producing such neutrinos results from photopion production by EHE cosmic rays in the cosmic background photon Ðeld. However, using assumptions for the EHE cosmic-ray source evolution that are consistent with results from the deep QSO survey in the radio and...
متن کاملSummary: Acoustic Detection of EHE Neutrinos
Neutrino astronomy was initiated primarily to search for TeV to PeV neutrinos from Active Galactic Nuclei, and the optical Cherenkov technique is well suited for this energy range. Interest has grown recently in detecting EeV neutrinos, particularly the “cosmogenic” neutrinos produced during propagation of ultra-high-energy cosmic rays (UHECR) through the microwave background radiation. These n...
