Neutrino Mixing and Future Solar Neutrino Experiments

Abstract

Possibilities of a model independent treatment of the data from future real-time solar neutrino experiments (SNO, Super-Kamiokande and others) are discussed. It is shown that in the general case of transitions of the initial solar ${\nu }_e$'s into ${\nu }_{\mu }$ and/or ${\nu }_{\tau }$ the total flux of initial 8B neutrinos and the ${\nu }_e$ survival probability can be determined directly from the experimental data. Lower bounds for the probability of transition of solar ${\nu }_e$'s into all possible sterile states are derived and expressed through measurable quantities.
