AbstractAn overview of the solar neutrino projects is given, with an emphasis on the complementarity of the different experiments (gallium, indium, heavy water,...) to solve the solar neutrino problem that was raised by the chlorine and the Kamiokande results. The separation of the different sources of neutrinos in the Sun would contribute significantly to the astrophysical understanding of the Sun. Some of the planned experiments could be able to pinpoint neutrino oscillations (within a wide range of parameters) almost independently of solar models. Projects which are particularly sensitive to a variation of the neutrino flux with time are also discussed.

Near Future

This review has four parts. In Part I, we describe the reactions that produce neutrinos in the sun and the expected flux of those neutrinos on the earth. We then discuss the detection of these neutrinos, and how the results obtained differ from the theoretical expectations, leading to what is known as the solar neutrino problem. In Part II, we show how neutrino oscillations can provide a solution to the solar neutrino problem. This includes vacuum oscillations, as well as matter enhanced oscillations. In Part III, we discuss the possibility of time variation of the neutrino flux and how a magnetic moment of the neutrino can explain the phenomenon. We also discuss particle physics models which can give rise to the required values of magnetic moments. In Part IV, we present some concluding remarks and outlook for the near future.

Good Agreement

The results of recent data from the 37 Cl , Kamiokande-II (K-II) and 71 Ga solar neutrino experiments are quantitatively analyzed. The results suggest that non-standard neutrino properties, instead of a non-standard solar model, are the correct explanation for the "solar neutrino problem." Assuming resonant neutrino oscillations, it is found that the "non-adiabatic" and "large angle" solutions are in quite good agreement with the data. The implications of these solutions for forthcoming solar neutrino experiments are discussed.

The Magnetic Field

We have considered the effect of the reduction of the solar neutrino flux on earth due to the deflection of the charged neutrino by the magnetic field of the solar convective zone. The antisymmetry of this magnetic field about the plane of the solar equator induces the anisotropy of the solar neutrino flux thus creating the deficit of the neutrino flux on the earth. The deficit has been estimated in terms of solar and neutrino parameters and the condition of a 50% deficit has been obtained: Qν grad H≥10−18 eG/cm where Qν is the neutrino electric charge, grad H is the gradient of the solar toroidal magnetic field, e is the electron charge. Some attractive experimental consequences of this scenario are qualitatively discussed.

Generic Description

In analogy with the classical Faraday effect for the electromagnetic wave, a Faraday effect for massive neutrinos is found to be somewhat generic description of neutrino oscillations when neutrinos traverse a dense medium with or without a magnetic field. It is found that the Faraday angle for solar neutrino problem as an illustration of the Faraday effect for a neutrino wave provides conceptually convenient parametrization of the various oscillations scenarios.
