The observed capture rate for solar neutrinos in the 37Cl detector is lower than the predicted capture rate. This discrepancy between theory and observation is known as the ‘solar neutrino problem’. I review the basic elements in this problem: the detector efficiency, the theory of stellar (solar) evolution, the nuclear physics of energy generation ...

The problems with solar neutrinos
AIP Conference Proceedings, 1995Nuclear fusion processes in the center of the sun produce neutrinos as well as photons. Detection of these neutrinos constrains both the intrinsic properties of the neutrinos, such as their mass and mixing, and the models of the sun used to calculate the solar neutrino flux.

A major crisis facing theoretical nuclear astronomers and physicists today is the apparently very low flux of neutrinos emitted by the Sun. Davis et al. report a measurement of 1.5 ± 1 s.n.u. (1 s.n.u. = 10−36 capture/Cl37/sec) which is a factor of 6 or so smaller than the theoretically predicted values.

Neutrino oscillations and the solar neutrino problem
European Journal of Physics, 1989Part of the interest in neutrino astrophysics has to do with the fascinating interplay between nuclear and particle physics issues — e.g. whether neutrinos are massive and undergo flavor oscillations, whether they have detectable electromagnetic moments, etc. — and astrophysical phenomena, such as the clustering of matter on large scales, the processes

THE SOLAR NEUTRINO PROBLEM AND BOUNDS ON SOLAR NEUTRINO FLUXES
Modern Physics Letters A, 1995We review the current status of the solar neutrino problem. A survey of the experiments and their results are given, and solar physics crucial to the understanding of these results are discussed. Semi-empirical methods are used to derive bounds on the fluxes of the three most important components (pp, 7Be and 8B) of the solar neutrino spectrum. The 8B

Solar neutrino experiments, designed to detect the neutrinos generated in the nuclear fusion processes in the Sun, provide the only direct way to test our basic understanding as to 'why the sun is shining'. For almost 20 years, the only experiment of this kind was the chlorine detector in the Homestake gold mine, South Dakota, USA, run by Ray Davis ...

Reexamination of neutrino oscillation solutions to the solar-neutrino problem
Physical Review D, 1991A deficit of solar neutrinos compared to the standard solar model prediction has been measured in both the Homestake and Kamiokande-II experiments, with quite different detectors. We analyze the parameter space for oscillations of two neutrinos to find regions that can explain both experiments.

One of the most intriguing problems in science is and has always been the understanding of our Sun. Despite their elusiveness, millions upon millions of neutrinos hit each human being every second. Unless a neutrino scores a direct hit on an atomic nucleus (which only rarely occurs), it passes through without leaving a hint of its passage.
