Four-neutrino oscillation solutions of the solar neutrino problem [PDF]
Physical Review D, 2000 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]
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 ...

The Solar Neutrino Problem [PDF]
Annual Review of Astronomy and Astrophysics, 1995 The solar neutrino problem has persisted for almost three decades. Recent results from Kamiokande, SAGE, and GALLEX indicate a pattern of neutrino fluxes that is very difficult to reconcile with plausible variations in standard solar models.

Quantum Field-Theoretical Description of Neutrino Oscillations in a Magnetic Field and the Solar Neutrino Problem [PDF]
Journal of Experimental and Theoretical Physics, 2021 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.

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 signal expected from the solar luminosity. The observed $^8$B solar neutrino flux is in good agreement

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 JournalThe 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.

Neutrino Oscillations and the Solar Neutrino Problem [PDF]
, 2000 I describe the current status of the solar neutrino problem, summarizing the arguments that its resolution will require new particle physics. The phenomenon of matter-enhanced neutrino oscillations is reviewed. I consider the implications of current experiments -- including the SuperKamiokande atmospheric and LSND measurements -- and the need for ...

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.

Constraints on decay plus oscillation solutions of the solar neutrino problem [PDF]
Phys.Rev.D66:113008,2002, 2002 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. Decay of a massive neutrino mixed with the electron neutrino results in the depletion of the solar neutrino flux.
