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

Four-neutrino oscillation solutions of the solar neutrino problem [PDF]
We present an analysis of the neutrino oscillation solutions of the solar neutrino problem in the framework of four-neutrino mixing where a sterile neutrino is added to the three standard ones.

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

Quantum Field-Theoretical Description of Neutrino Oscillations in a Magnetic Field and the Solar Neutrino Problem [PDF]
The processes of neutrino oscillations in an external constant almost homogeneous magnetic field are described in the framework of a new quantum field-theoretical approach.

Current Status of the Resonant Spin-Flavor Precession Solution to the Solar Neutrino Problem [PDF]
We discuss the current status of the resonant spin-flavor precession (RSFP) solution to the solar neutrino problem. We perform a fit to all the latest solar neutrino data for various assumed magnetic field profiles in the sun.

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

Constraints on decay plus oscillation solutions of the solar neutrino problem [PDF]
We examine the constraints on non-radiative decay of neutrinos from the observations of solar neutrino experiments. The standard oscillation hypothesis among three neutrinos solves the solar and atmospheric neutrino problems.

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

Solar Models with Helioseismic Constraints and the Solar Neutrino Problem [PDF]
Imposing a constraint of the sound-speed profile determined from helioseismology and updating the microphysics, we have revised our seismic solar model, constructed with the assumption of a homogeneous metal abundance distribution, and have shown that ...
