MSW mediated neutrino decay and the solar neutrino problem [PDF]

, 2001
We investigate the solar neutrino problem assuming simultaneous presence of MSW transitions in the sun and neutrino decay on the way from sun to earth.

Analysis of Solar Neutrino Data from Super-Kamiokande I and II [PDF]

Entropy, 2014
We are going back to the roots of the original solar neutrino problem: the analysis of data from solar neutrino experiments. The application of standard deviation analysis (SDA) and diffusion entropy analysis (DEA) to the Super-Kamiokande I and II data ...

Matter-enhanced three-flavor oscillations and the solar neutrino problem [PDF]

Physical Review D, Particles and fields, 1996
We present a systematic analysis of the three-flavor Mikheyev-Smirnov-Wolfenstein (MSW) oscillation solutions to the solar neutrino problem, in the hypothesis that the two independent neutrino square mass differences, {delta}{ital m}{sup 2} and {ital m ...

Solar Models and Astrophysical S-factors Constrained by Helioseismic Results and Updated Neutrino Fluxes [PDF]

The Astrophysical Journal
The ratio of metal abundance to hydrogen abundance of the solar photosphere, ( Z / X ) _s , has been revised several times. Standard solar models, based on these revised solar abundances, are in disagreement with seismically inferred results.

A possible solution to the solar neutrino problem: Relativistic corrections to the Maxwellian velocity distribution [PDF]

arXiv, 2001
The relativistic corrections to the Maxwellian velocity distribution are needed for standard solar models. Relativistic equilibrium velocity distribution, if adopted in standard solar models, will lower solar neutrino fluxes and change solar neutrino energy spectra but keep solar sound speeds. It is possibly a solution to the solar neutrino problem.

The Solar Neutrino Problem - An Update [PDF]

Phys.Rept.311:115-141,1999, 1998
The $^8$B solar neutrino flux as measured by Super-Kamiokande is consistent with the $^{37}$Ar production rate in $^{37}$Cl at Homestake. GALLEX and SAGE, continue to observe $^{71}$Ge production rates in $^{71}$Ga that are consistent with the minimal ...

Exotic Solutions to the Solar Neutrino Problem and Some Implications for Low Energy Solar Neutrino Experiments [PDF]

, 2001
In this talk, I review, from the phenomenological point of view, solutions to the solar neutrino problem, which are not provided by the conventional neutrino oscillation induced by mass and flavor mixing, and show that they can provide a good fit to the ...

Neutrinos from SN 1987A, Earth matter effects, and the large mixing angle solution of the solar neutrino problem [PDF]

, 2001
We study properties of the oscillation effects in the matter of the Earth on antineutrino 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 ...
