Solar neutrino experiments and determination of the neutrino oscillation parameters

Abstract

This paper investigates present evidence and future tests for neutrino oscillations from solar neutrino experiments. First we analyze solar neutrino data (chlorine, Kamiokande, and gallium) in the MSW framework, including all effects that are known to influence neutrino evolution from production to detection sites, and compare our analysis with others. Next we quantitatively discuss the potential of future solar neutrino experiments (SuperKamiokande, SNO, and Borexino) for testing the MSW hypothesis, with special attention to those tests that are independent of the solar model (energy spectra, charged to neutral current ratio).
