STERILE NEUTRINOS AND FUTURE SOLAR-NEUTRINO EXPERIMENTS

It is shown that future solar neutrino experiments (SNO, Super-Kamioka nde and others), in which high energy neutrinos will be detected (most ly from B-8 decay), may allow to answer in a model independent way the question whether there are transitions of solar nu(e)'s into sterile states. No assumptions about the initial flux of B-8 neutrinos are mad e. Lower bounds for the probability of transition of solar nu(e)'s int o all possible sterile states are derived and expressed through measur able quantities.
