Standard Solar Neutrinos [PDF]
Nucl.Phys.Proc.Suppl. 48 (1996) 335-342, 1996 The predictions of an improved standard solar model are compared with the observations of the four solar neutrino experiments. The improved model includes premain sequence evolution, element diffusion, partial ionization effects, and all the possible nuclear reactions between the main elements.

Is bi-maximal mixing compatible with the large angle MSW solution of the solar neutrino problem? [PDF]
Phys.Rev.D59:077301,1999, 1998 It is shown that the large angle MSW solution of the solar neutrino problem with a bi-maximal neutrino mixing matrix implies an energy-independent suppression of the solar nu_e flux. The present solar neutrino data exclude this solution of the solar neutrino problem at 99.6% CL.

Neutrino masses and solar neutrinos [PDF]
Physical Review D, 1992 It has been pointed out by Bahcall and Bethe and others that all solar-neutrino data can be explained by Mikheyev-Smirnov-Wolfenstein oscillations with $m({\ensuremath{\nu}}_{\ensuremath{\mu}})\ensuremath{\sim}{10}^{\ensuremath{-}3}$ eV consistent with ideas of grand unified theories (GUT's).

Detecting the upturn of the solar 8B neutrino spectrum with LENA [PDF]
Physics Letters B, 2014 LENA (Low Energy Neutrino Astronomy) has been proposed as a next generation 50 kt liquid scintillator detector. The large target mass allows a high precision measurement of the solar 8B neutrino spectrum, with an unprecedented energy threshold of 2 MeV ...

Âderna Fìzika ta Energetika, 2017 Solar neutrino oscillations are supported by KamLAND’s antineutrino measurements, but certain solar neutrino data – the observed shape of the 8B flux and the difference between day and night counting rates measured in Super-K – do not fit well with the ...

Helioseismology and solar neutrinos [PDF]
Solar Neutrinos, 2018 The studies of solar neutrinos and helioseismology have been closely intertwined since the first neutrino experiment and the first observations of solar oscillations in the sixties. Early detailed helioseismic analyses provided strong support for the standard solar model and hence a clear indication that the solution to the discrepancy between the ...

Solar Neutrinos: Where We Are, Where We Are Going [PDF]
Astrophys.J.467:475-484,1996, 1995 This talk answers a series of questions. Why study solar neutrinos? What does the combined standard model (solar plus electroweak) predict for solar neutrinos? Why are the calculations of neutrino fluxes robust? What are the three solar neutrino problems? What have we learned in the first thirty years of solar neutrino research?

Solar Neutrinos and the Decaying Neutrino Hypothesis [PDF]
Phys. Rev. D 92, 073003 (2015), 2014 We explore, mostly using data from solar neutrino experiments, the hypothesis that the neutrino mass eigenstates are unstable. We find that, by combining $^8$B solar neutrino data with those on $^7$Be and lower-energy solar neutrinos, one obtains a mostly model-independent bound on both the $\nu_1$ and $\nu_2$ lifetimes. We comment on whether a nonzero

Physics Letters B, 1994 We re-examine the neutrino decay solution to the solar neutrino problem in light of the new data from Gallex II and Kamiokande III. We compare the experimental data with the solar models of Bahcall and Pinsonneault and Turck-Chieze and find that neutrino decay is ruled out as a solution to the solar neutrino problem at better than the 98\% c.l.

Solar neutrino measurements in Super-Kamiokande-I [PDF]
Phys.Rev.D73:112001,2006, 2005 The details of Super--Kamiokande--I's solar neutrino analysis are given. Solar neutrino measurement in Super--Kamiokande is a high statistics collection of $^8$B solar neutrinos via neutrino-electron scattering. The analysis method and results of the 1496 day data sample are presented. The final oscillation results for the data are also presented.
