Two solar neutrino problems
Abstract
It is shown that there are two solar neutrino problems: (1) the incompatibility of the chlorine and Kamiokande solar neutrino experiments; and (2) the low counting rates in the gallium experiments. Eleven recently-published solar models give 7Be neutrino fluxes that lie within a range of +/-10% of the average value, a convergence that is independent of uncertainties in the measured laboratory rate of the 7Be(p,γ)8B reaction. If nothing happens to solar neutrinos after they are created (à la standard electroweak theory) and the operating solar neutrino experiments are correct, then the 7Be solar neutrino flux must be less than 50% of the solar model value. At least three of the four existing solar neutrino experiments must be wrong if. (1) standard electroweak theory is correct, and (2) the true 7Be neutrino flux lies within the range predicted by standard solar models.
