The steady vanishing of the three solar neutrino problems

Theory Division, Europian Organisation for Nuclear Research CERN, Geneva, Switzerland

Three problems have been claimed for solar neutrinos. First, it has been said for over 20 years that the flux of high energy neutrinos was substantially less than that predicted from solar evolutionary models. Second, it was claimed that there were violent fluctuations in the high energy neutrino flux and that their periodicity was close to that of the sunspot cycle. Third, recently evidence was presented that low energy neutrinos may also have a flux deficit. The second problem is shown to be unreasonable and in disagreement with the more recent Kamiokande experiment. The other two problems of flux are shown to be vanishing with time. This is not from a single cause but from a series of improvements of the input data to the models, to a better appreciation of the errors which had sometimes been significantly underestimated, and also some of the experimental values have increased with time indicating a learning curve for some of these very difficult experiments with very low statistics. Finally it is concluded that the evidence for any solar neutrino problem is not compelling.
